This is lovely,I thought about doing something similar but as a 'Dads taxi' app similar to Uber where my family can request rides. Partly because I sometimes struggle to remember where I supposed to be and when, but also because it might just be fun
Also helpful if you have teenagers and want to make it easy for them to not drink and drive
I really love the idea of an ecosystem of Apps Powered by Parents (APPs). Please reach out if you ever plan to implement it!
