No longer free. Was never warned that it was a trial for only a week. I've been using it for months. It also has ads. Pay 5 bucks once to check things off and get back ups. Given the lack of communication in changes, just find a free app that does the same unless you really like this one. General PSA: Don't click ads on any app, many contain viruses/malware for phones and companies don't vet there sponsors ever.

I had purchased the app ald now my data cannot be transferred to new device. The instructions mentioned after backup on old phone then open Backup & Restore on a new phone. However there is no way to open this function without purchasing the apps first even on a new phone. Hugely disappointed
