### 4/5 — Good App - But would like more graphical data

*2022-11-09*

This is a very solid app and for the 294 boiler controller being so new to the market, I see this as a great start. It really feels like the Tekmar product line is finally joining the era of modern touchscreen technology. 

The feature or improvement that I’d like to see the most would be more and better quality historical run time and temp data, preferably in a graphical format, available in the app. 

It bothers me how the Boiler Supply Temp graph on the overview screen only shows me data gathered while I’ve had the app open and on that screen, updating in 10 second increments, and that I can only see number of “cycles” for each boiler. 

It would be very useful to see historical data on that temp graph going back hours, days or even weeks. Additionally it would be very useful if instead of “# of cycles” for a boiler, I could press on the cycles and open a new screen showing me time on, time off and cycle duration. Throw in an average cycle run time and average time between cycles to really give us a rich data set. This can help identify issues such as short cycling.. 

Good start though!

**Developer response:** Thank you for the wonderful feedback. I've forwarded your feedback to the developer.
