Please fix the login retention

I’m giving this app 2 stars only because of the annoying login behavior. It does not use standard app behavior in that it forces you to re-enter your login info every time! Apart from that I like the app.

EMA App is improved, needs more

The EMA App v3.0.1 is much better than its predecessor. I am glad to see the update, better capability, and a little better interface.

It still needs improvements. For the Data page in Day view, the energy as displayed is not very useful. A more useful plot would be the cumulative energy production for the day.

For selecting the date, it would be good to have a single click to return to today’s date.

Another feature that would be nice to see is a way to compare performance on two days using an overlay. Could have two consecutive days, two days a year apart, or user-defined days. This could apply to other time periods as well.

The app should be getting regular updates.

Much improved

This app has been improved so much that I am satisfied with current version. It gives me the same information I can get from EMA website, including module performance, which is very helpful to identify a faulty microconverter. Good job!
