A mobile app studio · est. 2019

Mobile apps built
like infrastructure.

Aifinity is a small senior team that designs, engineers, and ships production mobile software for iOS and Android. We work with operators, founders, and product teams who care about how the thing feels in the hand.

Selected ships from the last 24 months.

Apps we designed, engineered, and shipped end-to-end. A handful of consumer titles, a handful of client builds. Full case studies on request.

“The first mobile shop we worked with that treated security UX as a product surface, not a checkbox.”

02 / Process

A studio, not an assembly line.

Every project moves through the same four phases. The same two senior people stay on it from the first conversation to the App Store review.

01 / Discovery

Find the real product.

Two weeks of paid discovery. We meet your team, audit existing surfaces, talk to customers, and write a short product memo with what we think the app actually is. You own the memo whether we continue or not.

2 weeks Fixed fee
02 / Design

Design through working software.

We design in Figma for direction and in TestFlight for truth. Every screen is prototyped in code before it ships. Weekly demos. Asynchronous feedback. No surprise reveals at the end of a quarter.

4–8 weeks Time + materials
03 / Engineering

Production-grade from day one.

Native Swift and Kotlin. No cross-platform shortcuts. Test coverage, CI, store metadata, crash reporting, observability, all wired in before the first internal build leaves the studio.

8–20 weeks Time + materials
04 / Launch & beyond

Stay on past the ship.

App Store submission, launch monitoring, the first six review cycles. Then a monthly retainer for ongoing engineering if you want it. Most of our clients keep us on past launch.

Ongoing Monthly retainer
03 / Studio

Eight people, no project managers.

A senior team of designers and engineers who write the code, sit in the customer calls, and read the App Store reviews. Remote, EU and US time zones.

We build mobile software the way good writers edit. Slowly, on purpose, and with someone over our shoulder who has shipped before.

Aifinity was started in 2019 by four engineers who wanted to make consumer apps without joining a venture-backed app factory. Today we are eight people. We have shipped sixteen apps to the App Store and four to Google Play. We work with three to five clients at a time and turn down most of what comes in.

i.

Native, every time.

Swift and Kotlin. No cross-platform compromise because the cost lands on the user, not us.

ii.

Senior hands only.

Nobody on our team has less than seven years of mobile engineering. We don’t outsource to juniors.

iii.

Ship, then keep shipping.

Launch is week one. We measure ourselves on the changelog at month twelve.

04 / Journal

Notes from the studio.

Field notes on mobile engineering, App Store readiness, and the parts of the work that nobody else writes about. Updated when we have something to say.

Apr 18, 2026 · 14 min

A field guide to App Store readiness for first-time mobile teams.

The thirty things we check before submitting a build. Half are review-board land mines, half are user-trust signals nobody talks about. With a printable checklist.

Why we still build for iPad, even when nobody asks.

It costs less than you think, signals more than you think, and gets noticed by the App Store editorial team. A short defence of the platform that founders forget.

Notes on shipping AVO Pro 4.0: what changed, what stayed.

A retrospective on the largest version we have ever shipped. New navigation model, new background engine, new pricing. What we got right and the two things we would do differently.
