Not too simple, not too complex
I have tried several meditation timers. Some of them were just too complicated, and I spent my attention fussing with settings instead of meditating. Samsara is just right -- it has every feature I need, but no superfluous distractions. Also, there is no "online community" ( huge distraction in a competitors app).
I particularly like Samsaras graphic: a circular arc that gradually completes to a full circle. In addition to being elegant, it lets me see how much time is left without putting on my glasses.
