How to Create an App for Free: What's Free and What Isn't

This guide is for students, indie hackers and founders who want to build an app without spending money, or with as little as possible. You'll get an honest breakdown of what's genuinely free, which costs you can't avoid, and a step-by-step zero-budget plan that takes you from idea to an app real people can use.

TL;DR: You can design, build and test an app for free, and you can publish a web app or progressive web app for free. Publishing to the stores is not free: Google Play charges a one-time US$25 fee and the Apple App Store requires the Apple Developer Program at US$99 per year. Free tiers also come with limits that bite as you grow, so plan your exit from each one.

The honest answer: which parts are free?

The short version: building is free, distribution through the stores is not. If you need zero cost all the way to real users, ship a web app first.

Step 1: Validate the idea for free

Before any tool, confirm people want it. Free validation methods:

1. •Ten conversations. Find people with the problem in Reddit threads, Discord servers, LinkedIn or your own network. Ask about the last time they faced it and what they did.
2. •A free landing page describing the outcome, with an email signup form. Many site builders and form tools have free tiers.
3. •A pre-launch post in a relevant community showing a mockup and asking for feedback.

If nobody cares at this stage, you've saved weeks. Our full guide on how to make an app covers validation thresholds and MVP scoping in more depth.

Step 2: Scope it so free tiers are enough

Free tiers are generous for small apps and hostile to big ones. Keep version one narrow:

• •One core job. A habit tracker that tracks habits. No social feed, no chat.
• •Few screens. 5–10 screens is plenty for a first release.
• •Avoid expensive features: video streaming, large file uploads, real-time chat, heavy AI calls and SMS verification all have per-use costs that free tiers don't cover for long.
• •Prefer email or social sign-in over SMS codes, which usually cost money per message.

Step 3: Design the screens for free

You have three free routes:

• •Paper and a phone camera. Sketch every screen, photograph them, and link them in a free prototyping tool. Underrated for speed.
• •Figma's free plan. Enough for a small project, with free community UI kits for iOS and Android.
• •AI design tools with free tiers. Generate screens from a description, then refine. Free allowances are usually small, so write your screen list first and spend generations carefully. We compare what each free tier actually includes in free mobile app design tools and their hidden limits.

Whichever route you take, floow's free design tools need no account and cover the assets every app needs:

• •App icon generator for every required icon size.
• •Splash screen generator for launch screens.
• •App Store screenshot generator for store listings.

Step 4: Pick a free build path

If you can't code

Start with a PWA built in a no-code tool, or a no-code builder's free plan. Publish it as a web app with a link people can add to their home screen. When people use it and you need the stores, that's the point to pay.

If you can code a little

Expo with React Native is the most forgiving free path to real iOS and Android apps. Flutter is equally capable if you prefer Dart. Both are open source, and both let you test on your own phone at no cost.

Step 5: Add a free backend

Most apps need accounts and data storage. Two backend-as-a-service options have free tiers that cover small apps:

• •Firebase (Spark plan): authentication, Firestore database, hosting and analytics. Some features, like Cloud Functions, require the pay-as-you-go plan.
• •Supabase (free tier): a Postgres database, authentication, storage and edge functions. Free projects can be paused after a period of inactivity, so it suits active development and small live apps.

Set up billing alerts or usage limits from day one if you ever attach a card, so a sudden traffic spike doesn't surprise you.

Step 6: Test for free

• •Android: install debug builds directly on your phone or share an APK with friends, at no cost.
• •iOS: with a free Apple ID, Xcode lets you install your app on your own iPhone, but the signing expires after 7 days and you need to reinstall. TestFlight for external testers requires the paid program.
• •Web and PWA: share a link. This is the fastest free way to get real users.

Run five short test sessions with people who match your target user. Watch them use it without helping. Fix what confuses them.

Step 7: Launch, free or close to it

Free launch: web app or PWA

Host it on a free tier, connect a free subdomain, and share it. Add a web app manifest and icons so users can install it to their home screen. On Android, Chrome can prompt users to install a PWA; on iOS, users add it via the Share menu in Safari.

Cheapest store launch: Google Play

A one-time US$25 registration fee gets you a Google Play developer account. New personal accounts must run a closed test with a group of testers for a set period before publishing to production, so start recruiting testers early.

Apple App Store

The Apple Developer Program costs US$99 per year. Apple offers fee waivers for eligible nonprofits, accredited educational institutions and government entities, but not for individuals. Budget for it once your app has proven traction on the web or Android.

Free tier limits that catch people out

1. •Store fees. The biggest misconception: no route puts an app in the App Store for free.
2. •Branding on free plans. Many builders add their badge or use their domain until you upgrade.
3. •Usage caps. Database reads, storage, bandwidth and function calls can run out with even modest traffic.
4. •Paused projects. Some free backends pause inactive projects, which breaks a live app.
5. •No code export. Some no-code free plans don't let you take your app elsewhere, which matters if you outgrow them.
6. •SMS and email sending. Verification texts and transactional emails are usually metered.
7. •Commercial use terms. Some free hosting tiers restrict commercial use; read the terms before charging customers.

FAQ

Can I really create an app for free?

Yes, you can design, build, test and launch a web app or PWA without paying anything. Publishing to the app stores costs money: a one-time US$25 for Google Play and US$99 per year for the Apple App Store.

What is the best free app builder?

It depends on your skills. Non-coders can start with the free plans of no-code builders like Glide or FlutterFlow, or build a PWA. If you can write some code, Expo (React Native) and Flutter are free, open source and produce real iOS and Android apps.

Can I publish an app on the App Store for free?

No. Apple requires membership in the Apple Developer Program, which costs US$99 per year, to distribute on the App Store or through TestFlight. Fee waivers exist only for eligible nonprofits, educational institutions and government entities.

Can I make money from a free app?

Yes. Common models are in-app purchases, subscriptions and ads. Apple and Google take a commission on digital purchases made through their stores, and both run reduced-rate programs for smaller developers, so check each store's current terms.

Do I need a Mac to create an iPhone app for free?

To build and submit a native iOS app with Xcode, you need a Mac. Cloud build services, such as Expo's, can build iOS apps without one, and a PWA can run on iPhone with no Mac at all.

Design it with floow

Before you build, get your screens right: describe your app on floow.design and get editable iOS, Android or web screens you can export to Figma or code. Try: "Design a 5-screen PWA-friendly habit tracker: welcome, sign in with Google, today's habits list, add habit form, and weekly progress chart. Simple, friendly, mint and white, works on small phones."
