Teams who let us hold the release button
Shared logic written once, native where it matters, so iOS and Android stay in step release after release.
No demo-only branches. Each fortnight you get a signed build, a plain-language changelog and a short walkthrough.
Architecture notes, runbooks and a two-week pairing window are written in from the start, not bolted on at the end.
Most studios hand you a design file and a repo that disagree with each other. Pick a discipline to see how we staff it.
Swift and SwiftUI builds that respect the platform: Dynamic Type, VoiceOver, widgets, Live Activities and a submission that passes review the first time.
Kotlin and Jetpack Compose tuned for low-end devices, patchy networks and eight years of OS versions — not just the flagship in the demo video.
Flutter or React Native when a shared codebase genuinely pays — with native modules written properly wherever the bridge would cost you frames.
Research, flows, prototypes and a component library handed over as tokens and specs — not a folder of screenshots and a hopeful conversation.
Auth, sync, offline queues, push infrastructure and APIs that hold up under a launch-day spike — designed for the mobile client, not adapted from a web one.
Automated device-farm runs, crash budgets, staged rollouts and monitoring that pages a human — so the 11pm incident is boring instead of memorable.
Move the controls. The number updates live using the same model we use internally to quote work — so what you see here is what turns up on the proposal.
Focused MVP — one core job, done well
Estimates assume a single-language release and no regulated-industry audit. The two-week scoping sprint replaces this range with a fixed figure.
Send this to an engineerWe are not here to replace an in-house team. We join your board, your standups and your repo, take the work that has been sitting in the backlog since spring, and leave your people free to hold the roadmap.

A slide that says "80% complete" means nothing. A build on your phone means everything. From the second sprint onward, every fortnight ends with a signed artefact you can open, tap and complain about.

Each stage has an exit condition you sign off before we spend a rupee or a dollar on the next one. Click through to see what you get at the end of each.
We map the flows, name the risks, cut what will not earn its build cost and put a real number on the rest. You leave with a plan you could hand to any studio.
Flows, a clickable prototype and moderated testing. Every state gets drawn — empty, loading, error, offline — so nothing gets invented during the build.
The squad works in your repo, on your board. Every second Thursday you get a signed build, a plain-language changelog and a short walkthrough video.
Store listings, screenshots, privacy declarations and review responses. The rollout starts at 5% with automatic halt thresholds wired to your alerting.
Two weeks of pairing with whoever inherits the app, then either a reduced squad for the next release, a light support retainer, or a documented goodbye.

Crash-free session rate we hold as a hard release gate.
Engineers, designers and testers on the permanent bench.
Filter by platform. Ask us about the fintech and healthcare work under NDA — we will walk you through the architecture without the logos.
Rebuilt a five-year-old hybrid app in Flutter with an offline-first cart. Checkout abandonment fell by a third in one quarter.
Native iOS app for ward rounds, built for one-handed use with gloves on. Cleared a HIPAA review with no findings.
Kotlin rewrite for rugged handhelds on patchy rural networks. The sync queue survives a four-hour dead zone without losing a scan.
Widgets, Live Activities and a booking flow that survives a sold-out drop. Peak traffic day handled 41,000 concurrent sessions.
React Native app for inspectors with camera capture, signature flows and a report generator that works with no signal.
Compose rewrite with downloadable lessons for low-bandwidth regions. Install size cut from 94 MB to 31 MB.
We ask for these six months after the final invoice, when the honeymoon is over and the app is somebody else's responsibility.
The handover pack was the part that surprised me. Our two in-house engineers picked up the codebase in a week and have shipped four releases since without calling anyone.
They cut a third of our feature list in the scoping week and were right about all of it. That one conversation saved more money than the whole engagement cost.
Our compliance team is famously difficult. Nimblestack turned up to the review with the audit trail already written. First submission, no findings.
Every second Thursday there was a build on my phone. After eleven years of agency slides, that alone was worth the rate.
Every engagement is cancellable with thirty days' notice and quoted before we start. No change-request theatre.
For teams who need a real number before they can ask for budget.
A full cross-functional team owning delivery end to end.

Ask us directlyA focused first release usually lands between $80,000 and $220,000 depending on platform count, backend complexity and compliance load. The estimator above uses our real internal model, and the two-week scoping sprint turns that range into a fixed figure.
You do, from the first commit. Work happens in your repository and your design workspace wherever possible. There is no licence to buy back and no vendor lock written into the contract.
Often, yes. We start with a paid two-week audit covering architecture, test coverage, dependency health and store standing, then tell you plainly whether to continue the codebase or replace it.
Yes — listings, screenshots, privacy declarations, review responses and the staged rollout. It is included in the squad engagement rather than billed as an extra line.
Two weeks of pairing with whoever inherits the app, then your choice: a light support retainer, a reduced squad for the next release, or a clean exit with documentation and a recorded walkthrough.
Four hours of guaranteed overlap with your working day, written into the agreement. Everything else runs asynchronously through written updates, recorded demos and a shared board you can read at any hour.
Short pieces on scoping, store review and the parts of app delivery nobody puts in a case study.
