Short answer: in 2026 an agency or freelance team charges somewhere between $15,000 and $150,000 to build a mobile app, and takes two to twelve months to deliver it. An AI mobile app builder does the same job for a subscription measured in single or double digits a month, and you have the first version on your phone the same day. The gap is real, and so are the things the cheap number leaves out. Both halves are below.
How much does it cost to build an app the traditional way
The ranges agencies publish for 2026 are consistent with each other: a simple app is quoted at $15,000 to $60,000, an on-demand or marketplace app at $60,000 to $120,000, an e-commerce app at $50,000 to $150,000, and anything called enterprise at $150,000 and up. Those are not padding. They are what it costs to pay people to do the following, one after another.
- Discovery and design: a few weeks of workshops, wireframes and a clickable prototype.
- Two codebases, or one cross-platform codebase, written by hand, then reviewed and tested.
- A backend: accounts, a database, file storage, hosting, and someone to keep it running.
- Quality assurance on real devices, then store listings, screenshots and review rounds.
- Changes after launch, billed by the day, because every change goes back through the same people.
How long does it take to build an app
The same sources put a simple app or MVP at two to four months, a medium app at four to seven, and a complex one at seven to twelve or more. That is calendar time, most of it waiting for the next person in the chain. It is the number that decides whether an idea gets tried at all.
What the same app costs with an AI mobile app builder
Here is our own price list, stated with what it buys, because a number on its own is useless. Every template is free: a finished app with sign-in, a database and file storage, on your phone with your name on the icon, no card. An app written from your own description costs about fifteen credits. A change afterwards, asked for in plain English in the app’s chat, is a few credits. New accounts start with five free credits. The plans differ only in how many credits they include: Basic is $5 a month with 50 credits, Pro is $19 a month with 250 credits, Business is $49 a month with 1000 credits. Every plan builds the same apps the same way.
On time: a template is on your Android phone in about ten minutes, waits included. An app from your own description takes longer, because it is planned and written from nothing while you watch the preview build, but it is the same sitting, not the same quarter.
The fees no builder can waive
Two costs belong to the stores, not to whoever builds the app, and they turn up in every route. Apple charges $99 a year for the developer account that any iPhone install needs. Google charges a one-off $25 for a Google Play developer account, and only if you want to be on the store: installing on Android phones from a link needs no account at all. Both accounts have to be yours, in your name or your company’s.
The costs a cheap quote hides
- The backend. Some builders make the screens and leave you to rent and wire up a database. Here the backend comes with the app; on the free plan it sleeps after an hour of quiet and wakes in about a minute, and paid plans keep it awake much longer. When you outgrow it, you move it into your own Supabase account and own the data end to end.
- The changes. An app is never finished. Ask what a change costs before you ask what the build costs. Here it is a few credits, not a day rate.
- The phone. A builder whose output runs in a browser tab is not a mobile app builder, whatever the price. Ask whether the thing installs with its own icon.
When the expensive route is still the right one
If the app has to pass a regulator’s audit, talk to hardware, or plug into systems your company already runs, a team that owns those integrations earns its fee. For an app with screens, sign-in, data and a backend, which is most apps, the agency price is paying for a process you no longer need. Anything in between, a map, a booking flow, a marketplace, a delivery app: start here first and find out for a few credits whether the idea needs the big number at all.
The question is not whether $40,000 is fair for an app. It is whether you want to find out if your idea works before you spend $40,000 on it.
