One codebase, both stores
Flutter or React Native for the shared product, with native Swift and Kotlin modules where performance or device APIs demand it.
Store submission handled
We prepare listings, privacy declarations and review responses, and we stay on the account until the build is live.
SaaS and MVP focused
Auth, subscriptions, push, offline sync and an admin dashboard come as a tested foundation, not as change requests.
Instrumented from release one
Analytics, funnels and crash reporting are wired before launch so the second sprint is driven by real user behaviour.

Frequently asked questions
1. Cross-platform or native — which should we choose?
Flutter or React Native covers around nine out of ten products and saves roughly 35% against two native builds. We recommend native only for heavy camera, Bluetooth, AR or background processing work.
2. What happens after the app is live?
You get four months of free maintenance covering OS updates, store policy changes and crash fixes. After that, most clients keep a small monthly retainer for feature releases.
3. How much timezone overlap do we get with your team in United Kingdom?
Four to six hours of daily overlap with United Kingdom business hours as standard, including a written standup before your morning and a live call whenever you need one. Escalations are answered within two hours during Mon-Fri, 9am-6pm GMT.
4. How does a dedicated developer engagement actually work?
You get named engineers, not a rotating pool. We agree the squad, run a two-week onboarding sprint against your codebase, and bill monthly per engineer with a 30-day notice period. You approve every hire and can swap a profile within the first two weeks.
5. What does the offshore collaboration workflow look like?
Your board stays the source of truth — Jira, Linear or Azure DevOps. We work in your repo with pull-request reviews, ship to a staging URL every Friday, and send a one-page weekly report covering what shipped, what slipped and what we need from you.
