Signed up. Added a few accounts. Tried adding a custom app and it wanted me to subscribe for $29 per month. I would happily pay for a service like this but not $300+ per year. As is, there is a free account or one targeted at businesses. What about an upgraded single user tier in the $50 per year range? Also, as others stated, permissions on Github, Dropbox, etc. seem excessive.
Agreed, right now I use a spreadsheet to track subscriptions, it works great. I think an app like this can replace and add value to a simple spreadsheet but $300 more dollars year to track services I already subscribe too is way to much. I would shoot for lower per year cost, around the $20 to $25 mark.
Seems like we'd have success also targeting this at consumers, for personal use. Something for us to think about.
