Android app development FAQs

• How much does Android app development cost?

  Our custom Android app development starts from $20,000, for a focused MVP that includes the design, the backend, an admin panel and the release on Google Play. The final figure depends on the scope, and it becomes a fixed price once you've tested the interactive prototype. When you bring the designs and a backend or API, an Android app on its own starts from $15,000.

• Do you use AI to build apps? Does that make them cheaper?

  Yes. Our developers work with AI coding agents such as Claude Code and Codex, AI drafts specs from our workshops and writes automated tests, and people review every change. Because we work at a fixed price, the time AI saves goes to you: a smaller senior team, a lower starting price (new apps from $20,000) and more of your product in each milestone. We don't sell hours, so there is nothing to discount.

• Is AI-written code safe and maintainable?

  Every change is reviewed by a senior developer before it is merged, covered by automated tests and built on the same architecture and conventions we use on every project. Your code and data are never used to train AI models. If you want a second opinion, our one-week code audit, from $1,000, reviews any codebase, ours included.

• How long does it take to build an Android app?

  Building a focused Android MVP takes about 8 weeks of development, split into three milestones. Every two weeks you get a demo call and a build you can install on your own Android phone. Workshops and product design happen first, under a separate contract, and end with the prototype you test before we fix the price. The last milestone closes with the Google Play release.

• Native Android or cross-platform?

  Native Android in Kotlin is the better choice when the app runs on dedicated devices, talks to hardware or needs deep Android features. Cross-platform with React Native or Flutter fits better when you need Android and iOS at launch and most screens are standard, because one codebase serves both stores. We make the call with you during product definition and put the reasons in writing.

• Can you take over an Android app built by another agency?

  Yes, our Android app development services include taking over apps built by other agencies and freelancers, in Kotlin or Java. It starts with a one-week code audit from $1,000. Then we move the signing key and the release pipeline to our team and ship the first fix release, usually within one to two weeks. From there the app runs under a maintenance plan with an SLA, and the audit fee comes off the first month.

• What happens when Google Play rejects or removes the app?

  When Google Play rejects an update or removes the app, we read the policy notice, fix what it points to or appeal through Play Console, and submit the app again. Under a maintenance plan, dealing with a rejection is included in the release work, not billed separately. We also keep the target API level, permissions and data safety details current, which are frequent reasons for a rejection.

• How do you keep the app working on new Android versions and devices?

  We keep Android apps working on new versions and devices under a maintenance plan with an SLA. We raise the target API level when Google Play requires it, update Kotlin, libraries and SDKs, and test on the devices and Android versions your users have. Critical issues are answered within 4 business hours and fixed within 1 business day. The plan starts from $1,500/month, with a 3-month minimum.

• Do you build apps for tablets, scanners and other Android devices?

  Yes, we build Android apps for tablets, rugged phones, barcode scanners and payment terminals, as well as for phones. Ontapp's bartender app, for example, runs on PAX POS terminals at venues and UK music festivals and takes card and cash payments. Every release is tested on the models your team actually uses, with QA and testing built into each milestone.

• How do I choose an Android app development company?

  Choose an Android app development company that can show you native Android apps on Google Play, gives you a fixed price before development starts, lets you test a prototype first and has a plan for Android updates after launch. As an Android app development agency, we fix the price only after you've tested the prototype, our Android work includes Glorify and Imobiliare.ro, and every app we build can stay with us under an SLA.

• Which time zone do you work in?

  Our team works 9:00-18:00 EET/EEST from Cluj-Napoca, Romania, which covers most of the UK and Western European working day. You get a demo call every two weeks, a shared Jira board and a dedicated Slack channel.
