The One Answer Question Thread
I like CubeTimer, you can save multiple sessions, so I have a session for each puzzle and start new ones every month. It keeps track of best mo3, mo5, ao5 and ao12. It also has scramblers for all WCA puzzles plus 8x8 - 11x11. It will keep track of BLD, OH and feet solves from other solve types on the same puzzle. No other timers I've tried have the ability to save and store this many sessions.
