I imagine you'd have to log and it finds a pattern. Problem is it can be related to factors the app doesnt have data on.

Another potential idea is biometrics I.e. what sports watches do. Not sure if that stuff is voodoo or real tho.

For a first version, i imagine relying on week's data of user logs and pattern would be a good start. If can potentially iron out other factors that can affect the energy levels.
