Buyers should beware this apps licensing terms. Buying a "lifetime" license is a sham in that it only allows use for the app of your current iDevices. Once you change devices, you will find that you cannot remove your old devices and register your new ones, therefore rendering the word "lifetime" a sham. I approached the developers in a friendly fashion (three times) and was rewarded with a "blah blah" reply each time. I had bought a family "lifetime" licence in March of 2020 and used up all my devices. On my new iDevice I had need of the app and was forced to purchase another "lifetime" license, spending NZ$88 on each occasion. Does it work? Yes. Is it value for money? NO. Many apps allow removal of old devices and registration of new ones. This app does not and based on on use per dollar I would never purchase this product again.
