ATTENTION!
This version is out of date. The 2021 version is ready, which knows a lot more, please download it. (You can find it in the 'More apps from developer' list with blue icons.)

The 2021 version can also handle 8 wallets. Recorded content can be sent by mail. (The free version only manages 2 wallets from which data from the first wallet can be sent. There are no other restrictions.)

Version 2021 already handles well the previous problems caused by the differently set font size of the phones.

Both versions are ad-free!

Further functional description can be found in the 2021 version data sheets.
(The free version is still being reviewed by Google and will not be released yet.
