Four short phases. No wasted motion. Every phase ends with a working artifact you can actually use.

Services

Six ways we build Android apps.

Every engagement lands as a small, well-behaved APK in your GitHub organisation with a clean release pipeline attached.

◉ 01 · Full build

Concept to Play Store.

Native Android app built lean. Kotlin, Jetpack Compose, MVVM. We target a small APK, low background footprint, cold-start under 900ms.

From £42k · 6–14 wk
◉ 02 · Feature sprint

One feature, done right.

Four-week sprint bolted onto your Android codebase. We match your style, merge clean, hand back tests. No new dependencies you didn't ask for.

£18k · 4 wk fixed
◉ 03 · Efficiency audit

Where the app is heavy.

Two-week deep read of your Android codebase. Report focused on APK size, cold-start, memory, battery, gradle build time. Prioritised for the next quarter.

£6.5k · 2 wk
◉ 04 · Rescue & rewrite

Get the app back on the rails.

Previous team left. App is unreleased or badly leaking. We stabilise, ship a version, then set the ground for a lean rewrite.

From £24k · Scoped
◉ 05 · Play Store launch

Submission and rollout.

You have an APK; we do the rest. Store listing, screenshots, feature video, staged rollout, first-week review-response process.

£4.5k · 2 wk
◉ 06 · Retainer

Long-term engineering.

Monthly capacity across your Android portfolio, used flexibly. Weekly async check-ins, quarterly efficiency review call.

From £8k / month · 3-month min
Programme

Four phases, short hops.

Every full build follows the same shape. We publish the shape so you can measure us against it.

01

Load.

Two weeks. Discovery workshop, product surface map, technical shape doc, prioritised scope for the build. You walk away with a written plan whether you continue or not.

◉ 2 WEEKS · £6.5K · REFUNDED AGAINST THE BUILD
02

Build.

Four to twelve weeks of engineering. Kotlin native, Jetpack Compose, MVVM. Weekly demo Fridays with a working APK, size and cold-start budget tracked from week one.

◉ 4–12 WEEKS · WEEKLY DEMOS · FIXED PRICE
03

Ship.

Two weeks of launch: store listing, screenshots, feature graphic, staged rollout, review-response process, monitoring dashboard shared with your product owner.

◉ 2 WEEKS · PLAY STORE SUBMISSION INCLUDED
04

Hand off.

Written handbook, architecture diagrams, live walkthrough with your team, 30-day post-ship support. After that: retainer if you want us, quiet exit if you don't.

What the clients say.

Loopfrog shipped an app that opens in half a second on our members' phones. Our old vendor's version took eight seconds to boot. Same hardware. That is the whole story.

They cut the APK by eighty-three percent and never once made us feel bad about the mess they inherited. Ninety-one percent crash reduction, six weeks, done.

Our carers run these apps on entry-level Android phones with 2GB of RAM. Loopfrog treated that as the first-class case, not the edge case. It shows.
