Been working on this for about a year. Basically my first real 'startup' since I launched Tinychat nearly a decade ago.
Essentially, this is google analytics for where you have been. It makes use of a local database on the phone itself so you have control over your data. The only external calls it makes are anonymous ones to either google or foursquare to get names of places if you stay there for more than 15 minutes.<p>This app was created to answer questions that are not possible to easily answer now, like "What are my top 10 restaurants in miami" or "when was the last time I was at the dentist". While perhaps the audience for such data isnt as large as social platforms, I believe that there is enough utility in this for it to succeed.<p>The app itself is built in react (so android version coming in next few weeks) and makes use of custom geofence zones to accurately (in testing, more accurate than any other app in the ios app store) get your location and track your path with minimal battery drain of about 3-5% per day. All this done in the background.<p>Right now, the analytics options are just getting started but we are building out a full suite of detailed 'drill downs' for people to explore their data, even with the ability for you to write your own queries if you choose.<p>Id appreciate any comments or criticisms, be as harsh as you want- This app was a huge undertaking and if there are shortcomings I want to hear them.
