Scam warning!
Initially this app was amazing and I had written a great review. Then today I tried to access it and my settings had gone, and the app was asking me to pay an extra 6 pounds to add them back - despite the fact that I had already paid 8 pounds to purchase the app in the first place. The app itself has no contact details or support link, and the "support page" linked form this page is a dodgy Google doc. Needless to say I’ve requested a refund. Stay away.
