Software that
respects you.
No ads. No accounts. No dark patterns. Just tools that do what they say and stay out of your way.
Simple by design
We strip things out until what's left is only what matters. That's not a philosophy — it's just good taste.
Zero ads. Ever.
Your attention isn't inventory. We get paid when you choose to pay us, not before.
Your data stays yours
Everything stays on your phone. No accounts, no servers, no one reading your notes but you.
Built to grow with you
Start free. Pay when it's worth it. No countdown timers, no guilt trips.
