Stage 03 · Building
Native-quality mobile apps people actually keep on their home screen.
Crafting reliable, consumer-grade mobile apps across iOS and Android from a single, efficient codebase.
The problem
The app keeps slipping, feels second-rate next to the competition, and building it twice for iOS and Android doubles the cost of every single fix.
How Sumago approaches it
UX-led design paired with cross-platform engineering — reach without doubling the build.
Who this is for
If any of this sounds like .
Mobile App Engineering is usually the answer to one of these four conversations — not to a feature list.
- 01
Every fix has to be built twice
Separate iOS and Android teams means two backlogs, two release cycles, and a feature that lands on one platform months before the other.
- 02
The app feels second-rate next to the competition
It works, but it doesn't feel considered — and users compare it to the best app on their phone, not to your last release.
- 03
The release date keeps moving
Store submissions, device fragmentation, and manual QA turn every launch into an event nobody can schedule around with confidence.
- 04
Nobody can say why users leave
Installs look fine, retention doesn't — and with no crash reporting or analytics wired in, the reasons are guesswork.
What you get
The artifacts an engagement .
Tangible things your team owns at the end — not a slide deck describing them.
- 01Store-ready iOS and Android builds from one codebase
- 02Release and versioning pipeline
- 03Crash reporting and engagement analytics wired in
- 04A design system the app can grow into
What changes
The difference this makes to .
Not what gets built — what it's worth once it's in people's hands.
Cross-platform reach
Higher engagement & retention
Faster time-to-market
The stack
One codebase, .
Cross-platform where it pays for itself, native where it genuinely matters — so reach never costs you two of every engineer.
