I am working on the second version of WhatDinner [0]. Initially marketed it as 'Tinder to decide what to eat’ and focussed on couples and families, but then only a fraction use it in family mode.
So, now I am changing the concept and helping users generally decide what to eat (documenting it here [1])
Thank you! The main difference is that DO charges per app, we charge per server. So with us you can buy one server and host as many apps on there as you can fit and only pay for the server, not the apps. We're also cheaper (but lack features like autoscaling)!
