iOS and Android app development, from idea to the stores.

Mobile apps, native and cross-platform

We build native and cross-platform apps for iOS and Android. Where it fits the product, one codebase serves both stores, which keeps the two apps in step and the budget in check. Where a feature needs the platform itself, we build for the platform.

Either way, the goal is the same: an app that is easy to learn, pleasant to use, and built on a codebase that holds up from the first release to version ten. Since 2017 we have delivered 60+ projects across nine industries, from fintech and health tech to gaming, e-commerce, and entertainment.

How a mobile project runs

1. Plan. We test the idea, decide what the first release will and will not do, and write it down. Everything cut here is something nobody has to debug later.
2. Design. UX flows, wireframes, and the interface, designed around what your users need on a small screen with one thumb.
3. Build, in daily increments. A senior squad designs and builds in parallel, and every day ends with a new build of the app that you can install and hold in your hand.
4. QA and store prep. We test on real devices, run a performance pass, and prepare the store listing, screenshots, and review notes.
5. Launch and after. A production build for the App Store and Google Play, submitted or ready for you to submit, plus a clean handover. Then we read the data and keep improving the app, if you want us to.

A calm launch day

Store review is the one step of a mobile launch that nobody controls, us included. What we can control is everything before it. We remove every avoidable reason for a rejection before anything is submitted: the listing, the screenshots, the review notes, and the testing on real hardware rather than only on simulators.

The review itself runs on the stores’ clock. Our job is to make sure that when it starts, there is nothing left for it to find.

No day ends without something you can touch.

A new app in two weeks

If you are launching something new, 2Sprint takes you from idea to a store-ready iOS and Android app in 14 days, starting at $5,000. You get a business and finance plan, a finished product built by a senior team dedicated to you, and full access to 2Sprint, the AI workspace we run every project in.

Some apps are bigger than 14 days, and that is fine. A sprint is still a good way to validate the first release; after that we continue under a fixed-price, time and materials, or dedicated-team arrangement. The full calendar is in how a two-week sprint works, day by day.

Related work

Our two public case studies are web products, but both were built to live alongside mobile apps:

• AdQuest gives app owners verified in-app actions instead of clicks. Its Quest SDK runs inside publisher apps, including through a WebView, and AI restyles it to match each host app.
• TwoSprint is the workspace where our 2Sprint clients follow their app being built, every day.

Both are our own products. More on how we work is in the journal.

Questions

Do you build for both iOS and Android?

Yes. We build native and cross-platform apps and ship to both the App Store and Google Play.

Will you submit the app to the stores?

You get a production build for the App Store and Google Play, submitted or ready for you to submit. The review itself runs on the stores’ clock, so we prepare everything that could cause a rejection before submitting.

How do you price a mobile app?

Pricing depends on scope, complexity, timeline, and team. We offer fixed-price, time and materials, or dedicated-team options. The two-week 2Sprint starts at $5,000. All contracts and payments are in US dollars.
