While we're talking about voice overs, let's talk about the one that actually matters - try turning on Voice Over mode and navigating the app the way a visually impaired user would. It is completely and utterly unusable.
I have folders with a few different groups of friends for sharing music and web links. Really a great tool - I'm sorry it didn't work out commercially, but I am so excited to see this open sourced!
The really strong guy at the gym has probably figured out the importance of rest. If you just watched him dead lift a ton of weight, odds are very good that he didn't dead lift the day before, even if he was at the gym working on something else. He also probably takes an entire week of active rest after every 6-8 weeks of heavy lifting. He's working his ass off, but he's also being smart about it.
This was the primary weak point in the implementation. Expecting users to recognize that they can click on the static-looking fields on the card (or relying on them to use tab to move between fields) does not pass the grandma test. It'd be great if you detected when a field had been fully filled out and moved to the next one automatically.
