How we build apps
Ads never interrupt
No ads while you measure, tune, play or spin. Full-screen ads only at natural breaks, and never on launch.
Pay once, not monthly
One small purchase removes ads for good. No subscriptions.
Your data stays with you
No accounts. What you create stays on your phone unless you choose to share it.
Works offline
Everything that does not strictly need the internet works without it.
