Not very easy to use and hidden charges

Been using this for 6 months.... While I like the reminders sent to my partner, I am not a fan of this app. Somewhat hard to use. No statistics. Pictures are not intuitive and pro version does not let you sync across your devices. I was charged AGAIN when trying to sync the data to my iPad. Clearly no way to transfer my data to new devices given that there is no login to identify yourself.
