"Excellent app! Dumpy level user's friend."
I'm an archaeologist and was looking for something to calculate elevations while using a dumpy level on site. This is an excellent app and speeds up calculating so I can get on to other work faster. I've only bought the one year, but will definitely pay for a lifetime subscription when it ends. $35 is pricey for an app, but it works and that's worth it over years of excavation.
