How it works

The way app development should have worked in the first place.

01 · Your team

Ask

Say what to fix or build, in the tools you already use.

02 · The AI workflow

Build

The workflow makes the change, runs the tests and the code review.

Bug fixesCopy changesNew screensStore rejectionsPush notificationsLoginPaymentsIntegrationsOnboardingCrash fixes
03 · You, on your phone

Try

A build on your phone. Approve it, then it ships.

triplefive is run by Alvar Aronija, a senior mobile engineer. No account manager, no outsourcing. He reads every release, and the workflow runs in production on Gymply, triplefive’s own app.

What you get

It’s “no developer to chase” better.

One fixed price instead of a hire or an agency. You approve every build.

Builds on your phone

Every change arrives as a test build with a note.

An engineer signs every release

Alvar reads every change before it ships.

Fixed monthly price

Pick how many changes a month. Held for twelve months.

Any React Native app, any state

Bare or Expo, any version, with or without tests.

Everything in your accounts

Code, workflow and record stay yours.

Month to month

Thirty days’ notice. No lock-in.

Report to merged fix in one working day. Three decisions from a person. This is what The First Fix puts on your app.

Questions

Frequently asked questions.

What counts as a change?

One request in plain language that becomes one test build. “The reps and weights aren’t visible” is a change. “Redesign the workout screen” is several — we’ll tell you how many before we start.

Our app was built by someone else and it’s a mess. Does that matter?

No. Any React Native app, any state, is the base price. We add what’s missing — tests, CI, builds — as part of The First Fix, and we don’t judge whoever came before.

What do you need from us to start?

Access to the repo, App Store Connect and Google Play Console in your company’s name, one person who can approve a build, and a phone with TestFlight. Nothing starts until those exist, and if they can’t be arranged within ten working days there’s no invoice.

What happens when the workflow can’t make a change on its own?

It goes to Alvar, and it counts as two changes. Store rejections and logic bugs always go to him. You’ll know within two working days which kind it is.

Who’s responsible if AI-written code breaks something?

Alvar. He reads every change before it’s built and signs every release. You approve every build on your phone before it ships.

Can we pause or stop?

The plan is month to month with 30 days’ notice. Everything is in your accounts, so stopping means you keep everything — the next engineer picks it up from the repo.

Is our code used to train AI?

No. It runs through Claude under commercial terms that don’t allow that. It’s used for your app and nothing else, and our copies are deleted within 30 days of ending.

Do you work with Expo? Old React Native versions? Flutter?

Expo and bare React Native, any version. Not Flutter or native-only apps.

How is this different from hiring a developer or an agency?

A developer is a salary before anyone directs the work; an agency bills hours whether a fix is small or not. Here the workflow does the routine work, Alvar’s time goes to reading and signing, and the price is fixed. There’s no account manager.

We’re not in Sweden. Does that work?

Yes. We work across the Nordics and in English; prices are in SEK, invoiced ex VAT.
