Android product line
Four Android products. Four jobs. One engineering practice.
The story
The difficulty
Ship several distinct Android products — finance tracking, GPS capture, screen recording, and a puzzle game — each with a clear job, store-ready quality, and no shared “template app” feel.
How we worked
We did not start with a shared UI kit and then invent four names. We started with the job: money awareness, visual proof, a walkthrough, a daily puzzle. Native Android, store-ready packaging, and a privacy story that matches what is actually on the device. The shared part is discipline — architecture, release, listing copy — not a single layout copied four times.
The path we took
A short roadmap — what had to happen, in order, before the work could go live.
- 01
Name the job
One sentence per product. If two products shared a sentence, one of them was not a product yet.
- 02
Ship the spine
A first version a person can use without an account wall, unless the job actually needs an account.
- 03
Package for Play
Title, description, Data Safety, and screenshots that show the real interface.
- 04
Keep them separate
Four listings. Four information designs. No “suite” that nobody asked for.
- 05
What can grow
Each listing can deepen. We do not promise rankings. The next slice is whatever the live product teaches us.
Where it stands
Treasure, MapSeal, Recora, and Sudoku are live on Google Play. They are recently launched first-party products. Downloads and rankings are not published here because those figures change and we do not invent them.
If you are still curious
The questions this work usually raises.
These are the next things people ask. Read them, open the live work if there is one, then tell us which part you want for your own project.
Why not one app with four modes?
Because a treasurer, a site engineer, a teacher recording a demo, and a commuter with a puzzle are not the same visitor. Mixing them would have made a catalogue, not four tools.
Is this client work or our own?
These are products we designed, built, and published ourselves. That is the proof we take into a conversation about a similar Android job.
What would a fifth product look like?
Another clear job, another native board, another listing. Bring the job. We will tell you if it is a product or a feature.
