Recently an application on the HN homepage caught my eye. It had the following properties:<p>* It was a personal tracker for arbitrary data. For example, you could record that you had a certain number of steps today, but you could also record that you read a book and what it was.<p>* It seemed to be primarily an iPhone app. I don't think there was an Android app, though there might have been.<p>* It was not a habit tracker like Loop.<p>* It hit the front page of HN sometime in the last month, but not in the last few days.<p>Unfortunately I put my phone down to play with my kiddos and forgot what it was, and perusing my history going back a few weeks along with Google searches hasn't turned up anything.
