Hi, everyone! We’re very excited to tell you that we have finally launched our Premium service. Please see the announcement here: https://turtlapp.com/2019/04/premium-launch/
Note that for the time being, the restrictions on profile sizes are not enforced because there’s not a good way to see the size of your profile in the current version of the app. Once this is fixed, we will start capping the free accounts at 50mb.
