Works great, but apparently not on iPhone 11s – iHandy Level Review

I’ve had my Field Biology class use this app for years for estimating tree heights. This year, several students had iPhone 11’s of one version or another, and we could not get it to work on any of them. Hopefully, this is a temporary problem, as this is/was easily the best clinometer app out there for accurate student use.
