Local first
Your everyday records belong on your device. Export and backup are there when you need them.
Independent software for ordinary life
Software that respects people.
Mauna Apps makes useful tools without turning people into a product.
Our first product
Adult-ish
Adult-ish is a free, local-first Android app for daily health and task management: weigh-ins, calorie logging, daily tasks, reminders, and an offline sky explorer.
It is designed for the small things that add up. Records stay on your device. There are no ads, subscriptions, premium upsells, accounts, or cloud-hosted primary data.
How we work
Built to stay on your side.
No enshittification
No advertising, surveillance business model, premium tier, or deliberately worse free version.
Less friction
Useful software should respect your time. We aim for clear, dependable tools with fewer unnecessary steps.
Honest limits
We say what a tool does, what it does not do, and when your device or a permission limits it.
Community-supported development
One complete app, free for everyone.
Adult-ish is free in full. Optional support will help sustain its development, never unlock a better version of the app.
We are building in public conversation. People who support the work will be invited into closer discussions about priorities, while feedback and the full app remain open to everyone. We will share practical ways to participate when they are ready.
