Avoid at all costs
Taking advantage of their mentally vulnerable userbase to make their cancellation process intentionally unclear and abusive. Misleads consumer into signing up for two seperate subscriptions, one for the actual app and one for "workbooks", glorified ebooks that you must pay concurrently for. Did not remind me of autorenewal, did not indicate that I still had an active subscription when I cancelled the main one, when I was charged surprisingly for several months at a time, lied about giving me a refund! They told me to close my paypal case and they would provide a partial refund. It has been over a month, and this has not happened. Deliberate scam or extreme negligence?
