How It Works

Three steps to launching a Rails mobile app on your application

We handle the entire process. You focus on your business.

01

Preview your app

We build a working iOS and Android app preview from your live application in about a week. You see exactly how the app looks and feels before any commitment.

02

We build and launch it

Our team builds the iOS and Android apps, handles App Store and Google Play submission under your developer accounts, and ships the launch playbook with you.

03

Grow the channel

Push automations through Klaviyo or OneSignal, native analytics, and ongoing performance reviews. The app picks up your site updates automatically; our team runs the iOS and Android side.

Most app builders rebuild your frontend. We build the app on the one you already run.

Your existing frontend powers the app, with no second build to maintain.

What you get from custom-native

Rebuilding your Rails frontend in React Native, Swift, or Kotlin

Custom native means turning your Rails app into an API, then recreating every screen, route, ActiveRecord-backed view, and integration in a mobile framework. Hotwire, Turbo, ViewComponent, and the rest of your customizations, have shipped do not translate without being rewritten on the mobile side. A real engineering project that duplicates the frontend logic your Rails team already built.

Every Rails feature shipped twice across two codebases

Once two codebases exist, every feature ships twice: once in Ruby, once in Swift, Kotlin, or React Native. Devise auth flows, Pundit policies, Sidekiq background jobs, and the rest of your store flows, have to stay aligned across two stacks. Within months, mobile and web behave subtly differently and someone has to reconcile both releases.

Limited to what your Rails APIs expose to the native build

Custom native is constrained by what your Rails routes and APIs expose to a separate native frontend. Hotwire and Turbo Frames, server-rendered ERB views, ViewComponent libraries, and the rest of your customizations, has wired in do not translate to native without being rewritten on the mobile side.

A separate tech stack with its own team and release cycle

iOS, Android, and mobile DevOps engineers are a separate hiring track from your Rails team, with a different language, a different release cycle, and ongoing maintenance that runs alongside (not inside) your product roadmap. For context: custom-native runs $500K-$1M+/year fully loaded.

What you get from MobiLoud

Your live application is the source for both web and app

Your Rails application powers the iOS and Android app. Every controller, every ActiveRecord model, every Devise session, and the rest of your store flows, carries through automatically. One Rails codebase to manage, not two.

Every Rails route, gem, and integration keeps working

Whatever Rails gem, controller, route, ActionCable channel, or third-party tool your team has wired in continues to run inside the app the same way it runs on the web. The same routes serve the app and the browser; nothing has to be reimplemented for a separate mobile stack.

Build for the app on the same Rails stack you already use

Our platform bridges your live Rails application to iOS and Android. We apply direct customizations to the app experience when needed, handle native SDK integrations (scoped add-on on Enterprise), and run the iOS and Android side. Your Rails engineers build for the app on the same Ruby, ERB, and Hotwire stack they already use, with our team guiding on what works well in the app.

Live in 6 to 8 weeks, not six months

We build, QA, and submit the apps under your Apple Developer and Google Play accounts in roughly 6 to 8 weeks from kickoff. The Rails application you already operate is the production foundation, so version one is real production code, not a mobile prototype.

Your customer success manager grows the channel after launch

Customer success sets up the push automations through OneSignal or Klaviyo, runs the launch playbook (smart banners, install prompts, email announcements), and reviews app performance monthly against Rails peers in your category on Enterprise.

Three things working together: your Rails application, our platform, our team

Your live Rails application powers every controller, view, and integration you have already shipped. Our platform bridges web to native and brings the native features built in. Our team builds, ships, and operates the iOS and Android app.

The native features your Rails application alone cannot deliver

App Store and Google Play presence, push on the lock screen, and deep links into any Rails route. Native navigation, persistent login, and in-app payments are wired in, with analytics tied into GA4, Firebase, or your existing tooling.

Your mobile team, on subscription: builds it, runs it, grows it

Replaces the mobile team your Rails team would otherwise have to staff. We build the app, run the operational track (submissions, OS updates, certificate renewals, reviewer back-and-forth), and drive revenue on the channel through Klaviyo or OneSignal push automations, the launch playbook, and monthly performance reviews. Patterns proven across hundreds of brands.

What Rails teams actually need to know

An app channel for Rails applications, without the storefront rebuild

Apps and push are now one of the highest-engagement retention channels in ecommerce and B2B, and the brands using them well are pulling repeat orders out of a channel email and SMS cannot reach the same way. The question is not whether a mobile app makes sense for the Rails application you have already built. It is how to launch one without rebuilding the Rails frontend you have spent years investing in.

Push reaches customers where email and search cannot

Email open rates have fallen for years, and the promotions folder eats a large share of what does get delivered. SMS works but carries TCPA-style compliance overhead, costs that scale with volume, and a customer-experience cap before opt-outs climb. The retention-channel ceiling for B2B portals, Solidus and Spree merchants, and marketplace operators on Rails sits well below where it used to.

Mobile apps change the shape of the channel. An icon on the home screen, persistent login, push notifications direct to the lock screen, and the install itself as a signal of your best buyers and repeat accounts. Push reaches the customer where email and SMS cannot, and app users are already opted in by definition.

Across the ecommerce category, app users convert at 3-7x mobile web rates, spend 10-50% more per order, and deliver roughly 3x the lifetime value. For B2B and Rails-based commerce teams, the same pattern holds across the MobiLoud roster (Pharmazone, Sleefs, XCVI, JF Petroleum on WooCommerce): that have already done the work of getting auth, catalog, pricing, and checkout right on the web: the app captures the repeat behavior the application has earned.

Every other path rebuilds your application from scratch

The other routes to a Rails mobile app all ask the same thing: rebuild your frontend in a separate codebase. Custom native (Swift, Kotlin, React Native) means turning your Rails app into an API and replicating every route, every ActiveRecord-backed view, every Devise session flow, every Pundit policy, every Sidekiq job trigger, every ActionCable channel, and every Hotwire or ViewComponent your team has shipped, all in a different language and on a different release cycle. The team then carries the duplicated work going forward: every catalog change, pricing rule, B2B account flow, and checkout tweak ships twice.

The cost is real (custom-native runs $500K-$1M+/year fully loaded for an enterprise-scale Rails rebuild), but the deeper problem is the duplication itself. You are not paying for a mobile app; you are paying to maintain a second version of your Rails application, separate from the first one, with a different language and a different team. DHH and the Basecamp team made this argument publicly years ago, after building their own Rails mobile apps the hybrid way.

Your stack stays the source; our team owns the iOS and Android side

MobiLoud is the combination of a native platform and a service team. The platform bridges your live Rails application to an iOS and Android app and brings the features a native app needs built in: push notifications via OneSignal callable from any Rails job or scheduled task, deep links into any Rails route, persistent session login, native navigation, smart banners, in-app payments, and analytics tied into GA4, Firebase, or your existing tooling. The native integrations you would otherwise build once-per-app are built into the platform once.

Together, your existing Rails application plus our platform is a custom mobile app experience, built on the Rails stack you already operate, not a second one you rebuild from scratch. Every gem, every controller, every ActiveRecord model, every Devise session, every Pundit policy, every Sidekiq job, every ActionCable channel, and every Hotwire, Turbo, or ViewComponent view that ships on the site shows up in the app automatically. Auth runs through your existing middleware. Payments run through whatever processor you have wired in. The same routes serve the app and the browser.

Your Rails engineers build for the app the way they build for the web application: Ruby, Rails, the gems they already use, Hotwire and Turbo, on the release cycle they already run. Our team guides on the app-specific patterns and applies direct customizations to the app experience when something needs to look or behave differently in the app. The native SDK integrations that come up infrequently (custom payments, native analytics, a third-party tool that needs a native bridge) we handle from our side, and we run the iOS and Android operational track: builds and submissions under your developer accounts, OS update cycles, certificate renewals, SDK rebuild deadlines every quarter, and store policy.

"I was able to spin up an app in two months. We weren't limited by the app builder."

Brent Stimmel, VP of IT at JF Petroleum Group, on launching their WooCommerce mobile app on MobiLoud.

After launch is where the channel actually compounds

We are focused on the results we see Rails customers achieve regularly. The launch playbook is where we start: install prompts on your application, smart banners on mobile web, QR codes, email and in-app announcements to your existing customer or buyer base, and an app-user incentive to drive the first wave of installs. The push strategy gets built into the integration we set up (abandoned cart, reorder prompts, back-in-stock, account-level promotional campaigns), running directly out of OneSignal and callable from any Rails job or scheduled task.

On Enterprise, the work continues past setup. Your customer success manager runs monthly performance checkpoints against peer Rails and ecommerce brands, builds analytics dashboards on the app channel, reviews what is working in the category, and proposes what to try next. Included monthly development time covers app-side tweaks, custom platform integrations, and direct support for your Rails team when something needs an app-side fix. The push strategy gets refined as the channel grows.

MobiLoud has served 2,000+ brands. The pattern above is what the channel delivers when it is launched and run properly. The fastest way to know whether it works for your Rails application is the free preview: we build a working version of your Rails mobile app from your live application in roughly 5 to 7 working days, so you can see exactly how it looks and feels before you commit to anything.

Questions Rails teams ask before they launch a mobile app

Get Your Free Preview

Yes. Rails is a Ruby framework that runs on the server, so it cannot be compiled to iOS or Android directly. What works is a different mechanic: the iOS and Android app uses a system WebView to render your live Rails application, with native navigation, push notifications, deep linking, and persistent login on top. From the user's perspective, it is an app installed from the App Store or Google Play. From your engineering team's perspective, it is the same Rails codebase, deployed once. Basecamp's mobile apps, built by the team that created Rails, use the same hybrid pattern.

No. The app uses the same Rails routes your web application already uses, including Devise sessions, Pundit authorization, controller actions, and any business logic. There is no separate REST or GraphQL API contract to maintain for the mobile side, and no parallel data layer to keep in sync. If your Rails app already responds well on a mobile browser, the app uses those same responses inside the WebView.

Hotwire, Turbo, Turbo Frames, Turbo Streams, and Stimulus all run inside the app the same way they run in a mobile browser. ActionCable websocket connections work as well, so real-time updates (chat, notifications, live order tracking) carry through. ViewComponent libraries render the same. The native side adds what the web alone cannot deliver: push to the lock screen, persistent login that survives session cookie expiry, deep links into any Rails route, and native navigation around the WebView content.

Push is delivered through OneSignal, integrated into the platform out of the box (Klaviyo is available for Rails commerce stacks on Solidus or Spree). You can trigger sends from the OneSignal dashboard, or call the OneSignal REST API from your Rails backend using any HTTP client (Faraday, HTTParty, or a Sidekiq job). Standard ecommerce and SaaS triggers (signup welcome, abandoned cart, back-in-stock, reorder prompts, transactional updates) are all wired the same way email or SMS would be from a Rails mailer or ActiveJob.

React Native and Flutter are full mobile frameworks. You rebuild the UI layer in the framework's language and wire it back to your Rails backend through APIs. That is a legitimate path if you have the team to staff, retain, ship, and grow a mobile codebase alongside your Rails work. MobiLoud is the alternative when you want to offload the entire mobile channel to a partner who builds it, maintains it, and drives revenue on it, with patterns proven across hundreds of brands. Your Rails engineers keep shipping the web; our team replaces the iOS and Android team you would otherwise have to staff, and the customer success motion compounds the channel after launch.

Performance tracks your web app. Modern WebViews on iOS (WKWebView) and Android (system WebView) are essentially the same rendering engines as Safari and Chrome, with comparable JavaScript execution and rendering speed. Turbo Drive and Turbo Frames feel fast inside the app for the same reason they feel fast in a mobile browser. The performance gap vs a fully native app shows up in heavy animation and complex gestures. For most Rails use cases (B2B portals, Solidus or Spree commerce, marketplaces, SaaS), the gap is not perceptible to users.

MobiLoud Business is $1,499/month with a $5,000 setup fee and a 10,000 MAU fair-use cap. For teams above that or with custom requirements (dedicated success manager, SLA, SDK integrations, multi-region, custom contracts), Enterprise is custom-priced. Building a custom native mobile app for a Rails application typically runs $500K-$1M+/year all-in. The MobiLoud subscription covers build, design, App Store and Google Play submission, push setup, ongoing maintenance, and OS updates as part of the service. For most Rails teams, the managed service is faster and cheaper than the blended cost of running an in-house mobile team alongside the Rails work.

Yes. Many Rails teams come to us after a year or two of operating a custom-native app and finding the maintenance load (OS updates, certificate renewals, SDK rebuilds, drift between mobile and web releases) heavier than the value it returns. The replacement path is a working preview built from your live Rails application, a side-by-side comparison with the existing native app, and a planned migration of the App Store and Google Play listings under your developer accounts so reviews and install base carry over.

You own everything around the app. Apps are submitted under your Apple Developer and Google Play Console accounts, so the listings, reviews, install base, analytics, and users are all yours. MobiLoud retains IP in the platform and code that builds the app. The app itself, the store presence, and the user relationships are yours. If you ever move to a different solution, the listings, reviews, and users stay with you.

We work with enterprise security and legal teams routinely. Standard documents are available on request: a Data Processing Agreement (DPA), General Data Protection Regulation (GDPR) compliance, insurance certificates. Service Level Agreement (SLA) and uptime monitoring are available as an Enterprise add-on. SOC 2 Type II is on our roadmap. Your customer data lives on your existing Rails app, not on MobiLoud servers. Your security and legal counterparts get the full documentation on the call.
