    Tell us the goal

    A rough note through the form on what you sell and what needs to change.

    We study your market

    How people find you today, where inquiries get lost, then a call in your working day.

  3. 03

    A written plan

    The work, who does it and how it is measured. Nothing starts until you approve it.

How we check an app developer before you meet them

Every developer passes four checks before you meet them: a technical test, a code review, a spoken interview in English and a reference check. Then you interview them yourself.

01

Apps they have worked on

Code and store releases they have shipped, reviewed by a senior colleague.

02

A practical task

A small screen or fix built on the platform you need.

03

English and references

A spoken interview in English, and a reference check with people they have worked for.

04

Your interview

You interview the developer about your app, and approve them before they start.

What hiring app developers from us means

Native apps are built with each platform's own tools. Google names Kotlin its preferred language for Android, with Jetpack Compose for interfaces, and Apple's SwiftUI is its framework for building interfaces across its devices. Our developers work in whichever your app uses.

By the hour or part-time: many apps need work only around OS updates and occasional fixes. See hourly developers for how hours are agreed and logged. Hourly work is bought in blocks of 40 hours, and part-time is a steady 80 hours a month.

Want the app built for you instead? See our mobile app development company page, outsourced web development or all our software development services.

Cost

What an app developer costs

We do not publish rates. We quote after we understand the role.

What affects the cost

  • iOS, Android or both
  • Seniority
  • Hourly, part-time or full-time

How we price

You see the rate and the terms in writing before anything starts. Every engagement is covered by an NDA, and the contract assigns the code and every deliverable to you once paid for; we keep no rights in it.

Questions buyers ask us

  • Yes. You buy hours in blocks of 40 and use them on the tasks you approve, which suits OS updates and occasional fixes. See hourly developers.

  • Yes. You can hire for one platform or both: Swift and SwiftUI for iOS, Kotlin and Jetpack Compose for Android.

  • Yes. Our Android developers work in Kotlin, with Jetpack Compose for interfaces.

  • You do. We work from your repository and release from your App Store and Google Play accounts.

  • Hourly work is bought in blocks of 40 hours. Part-time is 80 hours a month, and full-time about 160 hours a month. Every engagement runs month to month, with no long lock-in.

  • Yes. The first week is a paid trial on a real task from your backlog, so you can judge the developer before you go on.

  • Tell us, and we replace them within 10 business days at no extra cost.

  • Hourly work is bought in blocks of 40 hours; part-time is 80 hours a month and full-time about 160 hours a month, all month to month with no long lock-in. Every engagement is covered by an NDA, and the contract assigns the code and every deliverable to you once paid for; we keep no rights in it. You interview and approve every person before they start, and the first week is a paid trial on a real task. The people you hire are online at least 4 hours a day inside US Eastern time. If someone is not the right fit, we replace them within 10 business days at no extra cost. Every developer passes four checks: a technical test, a code review, a spoken interview in English and a reference check (for designers, a practical design test and a review of past work take the place of the first two). You get an estimate before work starts, hours go into a shared weekly timesheet that you approve before we bill, and the block you buy is your monthly cap unless you add hours in writing. Staff augmentation ends on 30 days' notice, with a handover.

  • Our developers work from India and are online at least 4 hours a day inside US Eastern time, with the rest of the overlap agreed to suit your day. We are available round the clock, 24x7, as per your location.
