How do calculations work?

End a line with =. Everything after the = belongs to the App and is rewritten when you change the line. Percent: 100 + 10% =. Variables: price = 100, then price * 3 =. Functions: sqrt, abs, round, ln, log, sin, cos, tan, min, max, and √, ², ^.

How do currencies work?

Write the amount with the currency and the target: 100 usd in eur =, 0.5 btc in usd =. Words and symbols in English and Russian are understood. Rates come from our servers and stay on the device, so it works offline.

How do I sync to another device?

Settings → Sync key: copy it, enter it on the other device under “Connect to another device”, tap Apply. Both devices then share the notes. Keep the key private: it is the only thing protecting the notes.

I lost my key

Open Settings on any device that still has the notes: the key is shown there. Without a device holding the key, the notes cannot be recovered; write to us and we will see what can be done.
