Yes, possibly you are correct and there is no algorithm in the app.
The application syncs constantly the progress with the server: if you are offline, then it pushes collected data back to server when the connection is available, and (regularly!) retrieves lists of cards to repeat or learn.
Anyway, it looks rather unlikely, since the only option for them to monetize Decks in this model is ads. And ads and API just don’t work together.
I won’t donate for changes I never asked for.They could made a poll to see if people is with or against it but no they though consumers will accept forced bad changes like big website are doing(youtube,facebook).
I suspect that Memrise had grand ambitions for its company and hired too many employees too fast, forgetting that it was the simplicity of the platform and wide user base that made it valuable. Now, with profits stagnating, it has realized that it will either need to expand into new markets, or painfully downsize.
Sad but very true. Anyone can make a business out a site like this but with retards at the helm this demise was very much inevitable. Most of us saw it coming (not this particular move but the platform’s general death), I reckon. (After all, IMHO the new versions of the official courses are worse than their predecessors, a change rolled out not so long ago.) Memrise got a bit too big for it’s boots and with a nice, inflated sense of worth bigged itself up, hired way too many people for their needs and started ‘fixing’ what wasn’t broke until death was assured… As @Waffletoaster said, there are easier ways for a company to commit corporate suicide – guess they just wanted it painful and messy.
Yes, sad about Memrise, had a nice community creating free courses and this is how they then support that. I doubt they will survive after this, but good luck.
