I’ve been using the app for almost a week and I enjoyed every practise. What I find as a major letdown is unability to buy Dojo, offline access or different features separately. I am absolutely not interested in premium but I find offline access necessary. I would rather move to another app then buy premium. (As a bottom note I think it is a marketing advantage to offer separate offers and some bundles on top of it. ) Lastly I will more likely spend small amounts of cash repeatedly (buying separate features) then buying a huge pack.
