Kudos on the transparency, it's refreshing.
Striking how low the numbers are on the Mac App store. It seems it just doesn't work in the same magic insanely huge way that the iPhone store works
A criticism: my take is you never really got many downloads, even when you got those first few thousand. Lame stuff on Cnet gets tens of thousands of downloads. Popular but unprofitable shareware gets millions.
Were people telling you that 10k downloads was really awesome? Did you have any engagement metrics (usage of the app) suggesting people were going bananas with time in the app?
If anybody from the team is reading, it's not really any of my business but I'm going to ask it anyway on the off chance they feel like sharing: it looks like there's a time line of at least 12 months (probably more factoring in time to MVP) and a team of anywhere from 4 to 6. How did you guy's sustain your living costs during that time, consulting, credit cards & savings, incubator money, day jobs?
Shame, best of luck in the future!
I am wondering what those valuable lessons might be.
iterate quickly (as fast as possible). keep the burn rate low. hire the best possible. get advice from people who've been there. users want features, listen to them & deliver when you can, but always value their opinions. Second that, always be nice to users. customer service = marketing.
just to name a few.
and of course there were many more lessons, those were the cliffsnotes, or tl;dr version
