One Tap.
Endless Possibilities.
Five beautifully simple apps built around one idea: powerful things shouldn't take more than a tap.
Five apps. One philosophy.
Every app in the One Tap family is designed to strip away friction — so you get the result, not the busywork.

Scan, edit, merge and sign PDFs in a single tap — every document tool you need, none of the clutter.

Turn your favorite photos into stunning collages in seconds, with layouts made for how you actually share.
One Tap Banglish
Type Bangla in English letters and watch it convert instantly — fast, accurate, built for real conversations.
One Tap Hisab
Track expenses, split bills and manage everyday hisab — without ever opening a spreadsheet.
One Tap Work Proof
Capture timestamped, location-tagged photos that prove the job is done — no more disputes, ever.
Built for people, not for feature lists.
Every product decision runs through the same six filters before it ships.

Software that respects your time.
Go One Tap is a small, focused studio building everyday productivity tools for the moments between meetings, classes and commutes. We believe the best software disappears — it does the job and gets out of your way.
Since our first release, that philosophy has shaped everything under the One Tap name: one clear purpose per app, one obvious action per screen, and one tap between you and the result.
- Independently built and maintained
- Privacy-first by default, not by settings menu
- Trusted by users across five product lines
One place for every policy.
Each One Tap app has its own privacy policy, written in plain language.
