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 subscriptions, no account needed, and your data is never sold. Just tools that respect your attention.

The lineup

Two out. One on the way.

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

Zero Shot X

Dry-fire training timer

A premium dry-fire practice timer for competitive shooters. Your microphone detects the trigger break — no extra hardware — with par drills, custom drill sequences, and video review.

Row & stitch counter

A row and stitch counter for knitting and crochet. Count from a widget or your Lock Screen, keep your place in your pattern with a bar that moves as you count, and set "decrease every 7 rows" once.

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.

Pay once, or not at all

One-time purchases where it makes sense. No subscriptions, no dark patterns.

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.
