Independent app studio

Sharp, private apps that do one thing well.

RandomFuse is a small studio building focused apps for iPhone and Android — no ads, no ad tracking, no account needed, and your data is never sold. Just tools that respect your attention.

The lineup

Four out. More on the way.

Each one is single-purpose, offline-first, and built to be the best at exactly what it does.

Woolpip
Row & stitch counter

Punchjar
Work hours tracker

A time clock for hourly workers. Clock in from your Lock Screen or a widget, watch your hours, overtime and pay add up as you work, and fix a forgotten punch without guessing.

How we build

Fewer features. Done right.

The same convictions run through everything we make.

Private by default

No ads, no ad tracking, and we never sell your data. No account needed: where an app offers one, it's optional. Each app's privacy policy says exactly what it shares, and why.

Free to try, fair to keep

Try every app free. Pay a fair price, shown up front, only if you rely on it: a one-time unlock or a plain subscription you can cancel anytime. What’s free stays free.

Offline first

The work happens on your device. Every app works without a connection, and your data is never locked in someone's cloud.

Single-purpose

Each app does one thing and does it better than the bloated alternatives. No clutter, no scope creep.
