You can use it by yourself, but it works really well if you invite another person (or people) to join the turn, then any turn changes are synced in real-time to each other.
You can also track chores for kids etc and whether you've paid them their pocket money.
I haven't figured out a pricing model yet so for now it's free, tbh not costing a lot for hosting at the moment, any ideas welcome.
Would love feedback good, or bad! If you're in Wellington NZ could swap you a beersies in exchange for your critique.
