I've just started using Focusmate today and love it - working online alongside one other person for a 25, 50 or 75 minute chunk. Brilliant idea - you chat for 20-30 seconds, sharing your goals and then the same again at the end, saying how you got on - you're on mute otherwise so just see them beavering away whenever your concentration is flagging.
However, I realise I'd really like one for students - ideally masters/PhD students (ie same as me)... not essential, just think I would like the vibe.
Any ideas?
