What an Android app costs to build
Where Android budgets diverge from iOS ones: a device matrix that costs real money to test, a release model that gives you more control, and a category of hardware that exists nowhere else.
- $15K – $90K
- What most Android projects cost
- 10–13%
- QA as a share of what it has to test — plan for the top of it here
- $55 / hr
- Blended across design, engineering, QA, and management
The engineering that makes an app expensive is largely platform-neutral. Offline sync is hard everywhere. A twenty-year-old ERP is unhelpful in both directions. Android’s specific contribution to the bill is concentrated in two places: testing, which costs more here than anywhere else, and the class of project that can only be built on Android at all.
Both are worth quantifying. The first is a real premium that honest quotes include; the second usually means the platform choice was made for you years ago.
What Android projects cost
The same three shapes as any custom mobile work, with the QA share sitting at the top of its band instead of the bottom.
$15,000 – $25,000
Focused first version
About 9–15 weeks
One workflow, one kind of user, a new backend, and a device list you have deliberately kept short. Naming the three handsets that must work, instead of saying "Android", is the cheapest scope decision available on this platform.
$30,000 – $55,000
Production build
About 3–5 months
Several workflows, multiple user types, an admin application, and a real device set covering the extremes of your fleet. Background work and notifications push testing toward the top of the QA band.
$55,000 – $90,000
Complex build
About 4–6 months
Rugged handhelds, integrated scanners, belt printers, offline shifts, kiosk mode, or a device management platform in the middle. This is the most common Android shape in logistics, field service, and retail back-of-house.
These are the three shapes of project that show up most often. Treat the boundaries as soft: work lands between the bands constantly, and a project can sit at the top on one dimension and the bottom on every other. The calculator prices the description you give it instead of sorting you into a box.
Fragmentation is a line item, not a talking point
Three specific things cost money on Android. The enormous count of distinct device models that gets quoted in every article is a statistic nobody can act on; these three you can plan around.
- Screen geometry
- Aspect ratios run from squat tablets to very tall phones, display cutouts sit in different places, and foldables change size while your app is running. A layout that was only ever checked at one size will break somewhere, and it will break for a customer rather than during your test pass.
- Manufacturer behavior
- Several of the largest manufacturers ship aggressive battery management that kills background work in ways stock Android does not. An app that syncs in the background can pass every test on one handset and quietly stop working on another from a different maker. That class of defect is expensive to find, cheap to prevent, and invisible until a user mentions that "it stopped updating last month."
- OS version spread
- Android users update slowly and the installed base spans many years of releases. Permissions, background execution, storage access, and notification behavior have each changed between versions, so "supports Android 9 and up" is an engineering commitment rather than a line in a spec. Every version below your minimum is a customer you chose not to have.
The practical answer is a small physical device set covering the extremes of your actual user base, plus a cloud device farm for breadth. In the model behind this calculator QA runs at 10–13% of the work it has to test; on an Android-heavy project, plan for the top of that band rather than the bottom, and expect a small line of its own for devices.
The most valuable thing a client can bring to an Android estimate is a list of the handsets their people carry. "Android" is a $10,000 range. "Four hundred Samsung A-series and about sixty Zebra TC-series" is a number.
Kotlin, Compose, and what the toolchain implies
Kotlin is the default language for Android and has been for years. Java codebases still exist and interoperate cleanly, so an older app can be extended rather than rewritten. A codebase that is half one and half the other carries a permanent tax, and it shows up as everything being slower rather than as a visible problem.
Jetpack Compose is the modern way to build the interface, and like SwiftUI on the other platform it is faster for ordinary product UI than the XML layouts it replaced. The same caveat applies: a mixed codebase costs more than either pure approach. With an existing app the honest answer is usually to build new screens in Compose and leave the working ones alone until they need changing anyway.
The maintenance cadence differs from Apple’s in a way that matters for budgeting. Android’s major OS release is annual, but the churn underneath it (build tooling, Gradle, the support libraries) arrives more often than that. On top of it, Google Play requires apps to target a reasonably recent API level to stay updatable on the store. That is an annual engineering obligation with a deadline attached, and it is the most common reason a neglected Android app suddenly cannot ship a bug fix.
Field hardware, which mostly does not exist on iOS
Rugged handhelds from Zebra, Honeywell, and Datalogic. Integrated barcode and RFID scanners. Belt and vehicle-mounted printers. Devices locked into kiosk mode by a management platform so the user cannot leave your app. Warehouses, delivery fleets, utilities, and retail back-of-house run on this hardware, and this hardware runs Android.
- $5K – $9K
- Talking to a physical device, before the surprises
- $10K – $19K
- A shift that has to keep working out of signal, and reconcile after
It changes an estimate in three specific ways. The scanner is normally addressed through the manufacturer’s own SDK instead of the camera, which is faster and far more reliable but adds an integration and a hard device dependency. Kiosk or lock-task mode means your app is the entire user interface, so every error state you would normally let the operating system handle is now yours. And a mobile device management platform sits in the middle of deployment, so releases go through someone else’s process on someone else’s schedule.
The testing has to happen on the real hardware in the real environment: cold storage, gloved hands, a loading dock where the Wi-Fi gives up ten meters from the door. This is the most common reason an Android project lands in the top band. It is also why those projects are worth building, because the thing they replace is usually paper.
Staged rollouts and the Play release model
A Google Play Console account is $25 once, against Apple’s $99 a year. That is the smallest of the differences between the two stores.
- $25 once
- A Google Play Console account
- $99 / yr
- The Apple Developer Program, for comparison
Review exists on Play and has become slower and stricter than it was a few years ago, so plan for it the way you would on iOS. The advantage arrives after approval: you can release to a small percentage of users, watch the crash rate, and halt the rollout if something is wrong. For an app that staff use to do their jobs, that control pays for itself the first time it saves a shift.
Play also provides internal, closed, and open testing tracks, so getting builds to pilot users takes no separate service and no separate approval. Combined with staged rollout, this is the part of Android a well-run project plans around from week one.
Why a project starts on Android
Android-first is usually a consequence of a decision somebody already made.
The fleet is already Android, because the hardware is cheaper per unit, the management tooling is established, and the rugged devices only come this way.
The audience is international. Outside a handful of wealthy markets Android holds the clear majority, and an iOS-only launch there is a launch to a minority.
The product serves the general public at scale, where reach matters more than average revenue per user.
The device has to be locked down, kiosked, or provisioned in bulk, which is routine here and awkward on the other platform.
If two or more of those are true, the platform question is already answered and the budget conversation should move on to the parts that are still open.
Common questions about Android app cost
How much does it cost to build an Android app?
A focused first version is usually $15,000–$25,000. A production Android application with several workflows, multiple user types, and an admin portal is usually $30,000–$55,000. Builds involving rugged handhelds, integrated scanners, offline shifts, or kiosk mode generally start around $55,000 and run to $90,000 or beyond.
Is Android more expensive than iOS?
Usually by a little, and the difference is testing. The engineering is the same; the device and OS matrix is wider. On a typical business app the gap is single-digit percent rather than double. It widens when the app does background work, uses sensors or the camera heavily, or has to run on hardware you did not choose.
How many Android versions and devices do I have to support?
Fewer than you think, if you decide deliberately. Supporting the last four or five major OS releases covers the overwhelming majority of active devices, and every version below your minimum is a smaller and smaller group. The bigger lever is naming the specific handsets your users carry. A defined device list turns an open-ended QA commitment into a finite one.
What does Google charge to publish an app?
$25 once to register a Play Console account, with no annual fee. Google takes a commission on digital goods and subscriptions purchased inside the app; physical goods and services delivered outside the app are exempt. Play does require your app to target a recent API level to remain updatable, which is a small annual engineering obligation rather than a bill.
Can one codebase serve both Android and iOS?
For most business applications, yes, and it is usually the right call. A shared cross-platform codebase costs about 35% less in application development than two separate native apps, which works out at roughly 15% of the whole project. Design, QA, backend, and store submission are unchanged; those still happen twice, or once each, regardless.
