Mobile Apps

Android apps that work across the devices people actually own

Android’s challenge is variety. An app that flies on a recent flagship can be unusable on the three-year-old mid-range handset a large share of UK users actually carry. We test against realistic device profiles, because that is where the reviews come from.

The problem this solves

Teams build and test on one high-end device, ship, and then collect one-star reviews about crashes and battery drain from users on hardware they never tried. Background work restrictions and OEM battery managers make this worse and are rarely accounted for.

What you get

Kotlin and Jetpack Compose

Modern Android with Compose UI, coroutines and the recommended architecture components.

Real-device testing matrix

Tested across low, mid and high-end profiles and multiple Android versions, so performance problems surface before your users find them.

Background work that survives

WorkManager scheduling that tolerates Doze mode and aggressive OEM battery managers — a very common cause of "notifications stopped working".

Play Store compliance

Data safety form, target API level compliance and permissions justification. Google enforces target API deadlines annually and delists apps that miss them.

Google Play Billing

Subscriptions and in-app purchases with server-side verification.

Staged rollout

Release to a small percentage first, watch crash-free rate, then widen — so a bad build reaches few people.

How we work

  1. Scope

    Features, minimum SDK and device matrix agreed, fixed price.

  2. Design to Material guidelines

    Platform-appropriate patterns from the start.

  3. Build

    Two-week cycles with internal-testing builds.

  4. Device testing

    Real-device sweep plus automated instrumentation tests.

  5. Staged rollout

    Percentage rollout with crash monitoring.

  6. Support

    Thirty days included, then an annual target-API compliance plan.

What you should expect

  • Verified performance on mid-range hardware, not only flagships
  • Background tasks and notifications that survive OEM battery managers
  • Play Store data-safety and target-API requirements met
  • Staged rollout with crash-free rate monitored

Built with

  • Kotlin
  • Jetpack Compose
  • Coroutines

Mainstream, well-supported technology — chosen so you can hire for it and so another team could take the project over.

Android App Development — your questions

Including the ones about cost, which most agencies leave off the page.

Typically £14,000 to £28,000 for a focused native app. Android can cost slightly less than iOS to submit but slightly more to test properly, because the device matrix is far wider. Fixed price after scoping.

We normally set a minimum SDK covering roughly 95% of active UK devices, which currently means going back several versions. Supporting older releases is possible but each one adds testing cost, so we make the trade-off visible with real distribution data.

Because several manufacturers ship aggressive battery managers that kill background processes regardless of Android’s own rules. It is a real and well-known problem. We handle it with WorkManager, high-priority messages where justified, and clear in-app guidance for the handsets that need a settings change.

Google requires apps to target a recent Android API level to remain discoverable on Play, and raises that bar annually. An app that misses the deadline stops being available to new users. We include the current requirement at launch and cover future ones in the maintenance plan.
