Hanna Lab

It does what it needs to, and a good job at that. BUT my only recommendation would be to add the timers during testing into the app, as well as adding timers in the photometer for all timed steps, such as the 30 second shaking for magnesium. If you have a 3 minute timer for waiting at the end of the magnesium test, you can do 30 seconds to time you shaking the reagent.

Great app with all the functions I need, I would update to five stars if they add a dark mode so I can save battery.

I’ve been using the app for about a year and it’s remarkable! Calibration is quick and I find it easy to read. I do wish that there were a few more customization options regarding data logging and calibration slope display.
