How It Works

Three steps to launching a Flask mobile app on iOS and Android

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 app 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 Flask frontend in React Native, Swift, or Kotlin

Custom native means recreating every Jinja2 template, every route, and every integration in a mobile framework, then wiring it back to your Flask backend through a REST API. A real engineering project that duplicates the frontend logic your team already shipped, and a first version your users mostly experience the same as your existing web app.

Every Flask feature shipped twice across two codebases

Once two codebases exist, every feature ships twice: once on the web stack and once in Swift, Kotlin, or React Native on the mobile side. Flask-Login auth, Flask-WTF validation, business logic, 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.

Limited to what your Flask-RESTful endpoints expose to the native build

Custom native is constrained by what your Flask routes and Flask-RESTful endpoints expose to a separate native frontend. Blueprint logic, Jinja2 server-rendered views, Flask-Admin panels, and the rest of your customizations, do not translate without being rebuilt 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 Python and Flask team, with a different language, a different release cycle, and ongoing maintenance that runs alongside (not inside) your product roadmap. For context: enterprise-scale mobile teams run $800K-$1.5M/year in-house, or $500K-$1M+/year through an agency.

What you get from MobiLoud

A managed iOS and Android app on your existing Flask application

Your live Flask app powers the experience and every flow your users already know. We deliver the iOS and Android app, the platform behind it, and the team to run it. Your engineers keep shipping on Flask, with our team handling the iOS and Android side.

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

Our platform bridges your live Flask app 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 Flask engineers build for the app on the same 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 Flask app you have already shipped is the production foundation, so version one is real, not a mobile prototype.

Your auth, APIs, and payment flows work inside the app

Whatever Flask extension, Blueprint, route, or endpoint your team has wired in continues to run inside the app the same way it runs on the web. Flask-Login sessions, Flask-SQLAlchemy queries, Celery jobs behind the scenes, and the rest of your store flows.

Push notifications, deep links, persistent login, ready out of the box

Push through OneSignal or your own provider, deep linking into any Flask route, persistent session login, and the rest of your store flows. The mobile features your Flask app does not already deliver.

Three things working together: your Flask app, our platform, our team

Your live Flask app powers every screen and every flow your users already know. Our platform bridges web to native and brings the native features built in. Our team builds, ships, and operates the iOS and Android app.

Our team

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

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

Your Flask stack

Your auth, APIs, payment flows, and business logic all run inside the app

Your live Flask app powers the storefront. Flask Blueprints, Flask-SQLAlchemy models, Celery jobs, and the rest of your store flows, run inside the app. Your existing engineers build app tweaks with the same Flask skills, no second codebase to maintain.

Jinja2 templates, Flask Blueprints, Flask-RESTful, any Flask pattern Every pip package and custom extension keeps working No second codebase for your business logic

What Flask commerce teams actually need to know

An app channel for Flask commerce teams, without the rebuild

The question is not whether a mobile app makes sense for the Flask application you have already built. It is how to launch one without rebuilding the Flask app 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, custom Flask commerce, and marketplace operators sits well below where it used to.

Mobile apps change the shape of the channel. An icon on the home screen, persistent session 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. The pattern holds across teams that have already done the work of getting auth, catalog, pricing, and checkout right on the web: the app captures the repeat behavior the site has earned. John Varvatos sees 10x revenue per app user vs mobile web. Pharmazone runs 63% of online revenue through the app channel. XCVI runs 4.8x revenue per user on the app vs the mobile web.

Every other path rebuilds your application from scratch

The other routes to a Flask mobile app all ask the same thing: rebuild your application in a separate codebase. Custom native (Swift, Kotlin, React Native) means replicating every Flask route, every Flask-SQLAlchemy model, every Blueprint, every Celery-driven workflow, and every Jinja2 template 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 (in-house mobile teams run $500K-$1M+/year fully loaded; agencies $500K-$1M+/year for an enterprise-scale Flask 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 Flask application, separate from the first one, with a different language and a different team.

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 Flask app to an iOS and Android app and brings the features a native app needs built in: push notifications via OneSignal callable from any Celery task or Flask view, deep links into any Flask route, persistent session login, native navigation, smart banners, in-app payments, and analytics tied into Firebase or your existing tooling. The native integrations you would otherwise build once-per-app are built into the platform once.

Together, your existing Flask app plus our platform is a custom mobile app experience, built on the Flask application you already operate, not a second one you rebuild from scratch. Every pip package, every Flask-SQLAlchemy model, every custom Blueprint, every Flask-Login flow, and every Jinja2 template that ships on the site shows up in the app automatically. Auth runs through your existing Flask-Login or Flask-Security setup. Payments run through whatever processor you have wired in. The same routes serve the app and the browser.

Your Flask engineers build for the app the way they build for the site: Python, Flask, the pip packages they already use, 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.

"The app's been invaluable to us. The cost we're paying versus what we're getting back is tenfold."

Nick Barbarise, Director of IT at John Varvatos, on running a MobiLoud-powered iOS and Android app on Salesforce Commerce Cloud.

After launch is where the channel actually compounds

We are focused on the results we see Flask commerce customers achieve regularly. The launch playbook is where we start: install prompts on your site, 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 Celery task or scheduled Flask job.

On Enterprise, the work continues past setup. Your customer success manager runs monthly performance checkpoints against peer Flask and commerce 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 Flask 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 Flask app is the free preview: we build a working version of your Flask mobile app from your live web app in roughly 5 to 7 working days, so you can see exactly how it looks and feels before you commit to anything.

Questions Flask teams ask before they launch a mobile app

Get Your Free Preview

Yes. Flask itself is a Python WSGI 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 Flask app, 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 Flask codebase, deployed once.

No. The app uses the same Flask routes your web app already uses, including any auth Blueprint, Flask-Login session, and business logic. There is no separate Flask-RESTful contract to maintain for the mobile side, and no parallel data layer to keep in sync. If your Flask app already responds well on a mobile browser, the app uses those same responses inside the WebView.

Push is delivered through OneSignal, integrated into the platform out of the box. You can trigger sends from the OneSignal dashboard, or call the OneSignal REST API from your Flask backend using any HTTP client (requests, httpx, or a community Flask extension). Standard ecommerce and SaaS triggers (signup welcome, abandoned actions, re-engagement, transactional updates) are all wired the same way email or SMS would be from a Celery task or a Flask view.

React Native and Flutter are full mobile frameworks. You rebuild the UI layer in the framework's language and wire it back to your Flask backend through APIs. That is a legitimate path if you have the team to staff, retain, ship, and grow a mobile codebase alongside your Flask 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 Flask 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. If your Flask app loads fast on mobile Safari and mobile Chrome, the app feels fast. The performance gap vs a fully native app shows up in heavy animation and complex gestures. For most Flask use cases (custom ecommerce, B2B portals, marketplaces, internal tools with commerce flows), 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 an enterprise-scale Flask application typically runs $500K-$1M+/year through an agency. In-house, an iOS/Android team is $500K-$1M+/year fully loaded. 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 Flask teams, the managed service is faster and cheaper than the blended cost of running an in-house mobile team alongside the Flask work.

Yes. Many teams reach us after building a custom native app on top of a Flask backend and finding the maintenance load (separate codebase, separate team, OS update cycles, store policy churn) heavier than expected. The replacement path is a working preview built from your live Flask app, side-by-side comparison with the existing custom app, and a planned migration of the App Store and Google Play listings under your developer accounts so reviews and install base carry over. Most replacements ship in 6 to 8 weeks once scoped.

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 Flask app, not on MobiLoud servers. Your security and legal counterparts get the full documentation on the call.
