MyThermowatt allows you to control the temperature of your water heaters remotely, via Smartphone or Tablet. You can minimize waste by heating the water only when necessary, for example while heading back home from work, after practicing sports or before arriving to the vacation house. You can turn the water heater on or off wherever you are, manage its temperature and its switch-on/off times and always be updated on its operating status. The correct usage allows a consumption saving of over 15%. MyThermowatt also allows you to intervene promptly in case of malfunctioning of the water heater, by sending you a notification with specific instructions to solve the problem, in order to avoid a cold shower when returning home!

Verdict
The clearest difference is update cadence: MyThermowatt at every 2 months against A2O's every 11 months. A2O's advantage is iOS requirement (13.0 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.
