Independent apps.
Made for everyday use.

NNRZONE is an independent studio. Each app starts with an everyday need, like finding the chords to a favourite song or knowing whether today's meals were on track, and keeps the answer one tap away.

More apps are on the way. They'll all live here.

Your data stays yours

No sign-up walls. What you log lives on your phone unless you choose to back it up.

Works offline

Songs, logs and reports load fast and keep working without a signal.

Free to use

Supported by light ads, never by selling your personal data.
