Mobile app development services
Most mobile projects are not hard because of the screens. They are hard because of the state: what happens when the network drops, the device sleeps, the pairing fails, or the user reinstalls.
Companion apps are their own discipline
An app that talks to hardware is not a normal app. BLE connection state is not a boolean, pairing gets lost, the operating system kills background scans, and both platforms change their permission model regularly. A team that has only built API-backed apps meets these facts one at a time, in production.
Because we build the firmware too, we design the protocol between device and app as one thing. That removes the most common failure mode in connected products: two teams each implementing half of an under-specified protocol.
What we build
Cross-platform in Flutter or React Native where a shared codebase is the right economics, native where a platform capability or performance requirement demands it. We will tell you which applies rather than defaulting to whichever we prefer.
Device pairing and control, offline-first data with conflict resolution that has actually been thought about, push notifications, background sync within what each OS genuinely permits, and store submission — including the review-rejection cycle, which is a normal part of shipping rather than a surprise.
Design and handover
Interface design is part of the work, not a separate purchase. Screens follow each platform's conventions rather than fighting them, which is both faster to build and less confusing to use.
You get the repository, the build and signing setup, and store accounts in your own name. An app you cannot ship an update to without us would be a liability, not a deliverable.
Questions
What people ask before starting
Flutter, React Native, or native?
Flutter when you want one codebase and a consistent look you control, React Native when the team already lives in TypeScript and React, native when you need deep platform integration, sustained high performance, or the newest OS features on release day. For a BLE companion app any of the three can work — the deciding factor is usually which stack your team will maintain after we hand over.
Can you fix or take over an existing app?
Yes. We begin with a code and dependency review, because the usual finding is an app two or three OS versions behind on its dependencies, where the first job is getting it building and shipping again before any feature work is sensible.
Do you handle App Store and Play Store submission?
Yes, under your developer accounts rather than ours. That matters more than it sounds: an app published under an agency account is genuinely painful to move later. We will also handle the first rejection, which is common and rarely serious.
How do you deal with background BLE limits?
By designing around them from the start, because both platforms restrict background scanning and connection in ways that will not change to suit your product. In practice that means being explicit early about which behaviours are possible in background, which require the app in foreground, and which need a hardware-side change to work at all.

One technical call is usually enough to tell you whether this is straightforward, genuinely hard, or the wrong approach entirely. We would rather say so early than quote for the wrong thing.
