Quick answer: Can I really make an app for free?
- Building can be free: no-code free plans, MIT App Inventor, Firebase Spark, Supabase Free.
- Publishing costs money: Google Play US$25 once, Apple US$99 a year.
- Free tiers end at usage limits, inactivity pauses, branding, custom domains and SMS.
- Your time is the real cost — budget weeks, not hours.
Key takeaways
- 'Free' is a stage, not a business model. Plan the first paid step before you need it.
- Free backends are genuinely generous for prototypes — Firebase gives 50,000 Firestore reads a day; Supabase gives a 500 MB database.
- Read the limits that bite first: Supabase pauses free projects after a week of inactivity; phone (SMS) login costs money almost everywhere.
- Builder free plans often add their branding, cap users or block publishing to stores.
- If the app works, a small paid plan is cheap compared with rebuilding on a different platform later.
"Free" is the most clicked word in app-making searches and the most misleading. You genuinely can build a working app without paying anything. What you cannot do for free, for long, is publish it widely, grow it, and keep it running. Here is exactly where the money starts — so you can plan for it instead of being surprised by it.

The short answer
| Stage | Free? | What it really costs |
|---|---|---|
| Learning and prototyping | Yes | Your time |
| Building a small app | Yes, on free tiers | Your time; free-tier limits |
| Publishing on Google Play | No | US$25 once4 |
| Publishing on the App Store | No | US$99 a year5 |
| A web app or PWA | Mostly | A domain (a few hundred to a few thousand ₹ a year) |
| Growing past free limits | No | Paid builder, backend and service plans |
The free toolkit

Free builders
MIT App Inventor is free and block-based, built for learning to make Android apps3. Many no-code builders also have free plans for prototypes — typically with their branding, user caps or no store publishing.
Free backends
Firebase's Spark plan needs no payment method and includes daily quotas such as 50,000 Cloud Firestore reads and 20,000 writes1. Supabase's free plan includes a 500 MB database per project2.
Free hosting
Static sites and PWAs can be hosted free on several platforms, and Firebase Hosting includes 10 GB of storage on Spark1.
Free design and testing
Free tiers of design tools, Android emulators, and real-device testing quotas on many services.
Where "free" ends: the limits that bite first
| Limit | Typical trigger | Typical next step |
|---|---|---|
| Database size or reads | A few hundred active users | Backend's first paid tier |
| Inactivity pause | A week without traffic | Paid tier, or keep a scheduled ping |
| SMS / phone login | First real users | Pay per SMS, or use email or Google sign-in |
| Builder branding | Showing it to customers | Builder's starter plan |
| Store publishing | Launch | US$25 Google Play; US$99/year Apple |
| Custom domain and email | Launch | Domain and email plan |
A realistic ₹0 → paid path

- ₹0 — learn and prototype with a free builder or MIT App Inventor and a free backend.
- ₹0 — test as a web app or PWA with real users; no store fees needed. See what a PWA is.
- ~₹2,100 once — publish on Google Play (US$25), running the 14-day closed test new personal accounts need6.
- Low monthly cost — the first paid tiers when you outgrow the free limits or need to remove branding.
- ~₹8,500 a year — add iOS (US$99) when your users or revenue justify it.
The cost nobody counts: your time
A "free" app built over twelve weekends is not free if those weekends could have earned money or tested three other ideas. Be honest about the trade:
- Use free tools to learn and to test demand fast.
- Pay for tools as soon as they save you more time than they cost.
- Hire help when the app needs features beyond the tool, security you cannot verify, or speed you cannot provide.
Can a free app make money?
Yes — through ads, in-app purchases, subscriptions, or by supporting a business that earns elsewhere (a clinic's booking app, a coaching centre's fee tracker). But by the time an app earns real money, it almost always runs on paid tiers. That is a good sign, not a failure: the tiers cost far less than the revenue they support.
Key terms, defined
Free tier — a no-cost plan with usage limits. Backend — the server side that stores data and handles logins. Spark plan — Firebase's no-cost plan. Blaze plan — Firebase's pay-as-you-go plan. PWA — a progressive web app, a website that installs and behaves like an app.
Frequently asked questions
Can I make an app for free?
You can build and test one for free. Free plans of no-code builders, MIT App Inventor, and free backend tiers such as Firebase Spark and Supabase Free cover prototypes and small apps. Publishing costs money — US$25 once for Google Play and US$99 a year for Apple — and growth usually means a paid plan.
What is the best free app maker?
For learning and simple Android apps, MIT App Inventor is free and beginner-friendly. For data-driven apps, no-code builders with free plans work for prototypes. For a free backend, Firebase's Spark plan and Supabase's free plan are generous. The best choice depends on whether you need stores, data and custom logic.
Is publishing an app on Google Play free?
No. Google Play charges a one-time US$25 registration fee for a developer account. There is no annual fee. New personal accounts must also run a 14-day closed test with at least 12 testers before publishing to production.
What are the hidden costs of a free app?
Store fees, a custom domain, removing the builder's branding, more users or storage than the free tier allows, SMS for phone-number login, email sending, paid integrations, and the time you spend building and maintaining it. Many apps also eventually need a developer for features the free tool cannot do.
Can a free app make money?
Yes — through ads, in-app purchases, subscriptions or by supporting a business that earns elsewhere. But a free plan rarely supports earning at scale; by the time an app makes money, it usually runs on paid tiers that cost far less than the revenue.
Is Firebase free for apps?
Firebase's Spark plan is free with no payment method and includes daily quotas — for example 50,000 Cloud Firestore document reads and 20,000 writes a day. Some features, such as phone authentication by SMS, need the pay-as-you-go Blaze plan.
