Just a quick update to this thread. The review timer will be displayed in the app in the next beta (and production) releases, which should be coming out for beta testing sometime next week!
P.S. Here’s how it’ll work. Continuous Review a separate button in the app. The continuous mode will display the study timer (the top bar is very bland without it), while due count review will continue to focus on due cards, not time. We’ll be cleaning up cheers and adding them back into the app in a future version (probably 3.3.7 if I had to guess) to give some more global time indicators for everyone.
After internal testing with the study timer, this is probably the best way to split it without horrible things happening to study time when you’re just focusing on due cards. Reason being, the study time needs to sync with the server (this is how we track progress on multiple clients, it is also how cards get sorted in your queue and keep track of total time spent per card). We can manually calculate some things on the client, but if the server doesn’t sync immediately while you’re studying due cards Skritter time just jumps around and makes no sense. Things go into a global queue, and some syncs can take upwards of a minute to complete if lots of people are studying at the same time. Eventually, it’ll correct, but it is very unpredictable when that’ll happen, and often requires leaving the session, waiting for sync, and then returning to study. Not fun. So… due count for focused study on due cards. Continuous more a more zen (time focused) study session.
Added bonus. This will also allow us to explore new ways to tuning card scheduling in the future, and will be the groundwork for supporting some kind of adding system similar to the website and older mobile clients.
