No need to clutter your phone with tiny apps. The Tukuk app collection opens instantly in the browser — use it once, close it, and come back when you need it.
Small apps that need no installation
Every phone is full of apps we use once in a while: a calculator, quick notes, a metronome, a timer. It is sad when each one eats storage and permissions. The Tukuk app collection (tukuk.org/apps) exists for exactly that — mini apps that run right in the browser. Open the link, use it, close it. No install, no forced updates, no noisy notifications.
What is inside?
Among the things you can try instantly:
- Calculator — quick math, including for everyday work.
- Notes — scribble ideas, stored locally on your device.
- Piano & Drums — play melodies and rhythms; there is a learning mode.
- Format converter — change files from one format to another.
- Background remover & Collage — simple image tools.
- Mini arcade — small games for a quick break.
All one page, one style, and lightweight.
If you like it, then install it
Want faster access? Any app can be "Added to Home Screen" as a PWA — it opens full-screen with its own icon, feeling like a regular app. On Android, some can also be downloaded as an APK from the app hub (tukuk.org/). But it is optional: you are never forced to install to use.
The "open and go" philosophy
The design is deliberately light: apps you do not use do not haunt your phone. When needed, search, open, finish the task. A life without managing 40 apps that each get used once a year — that is the promise of browser apps, and that is what we built.
