It’s a striking feature set but ultimately it’s behind a $10 paywall to really use. Its star feature is distance measurement which is the main reason to use the app over the many others but it’s limited to 1m without paying $10. I’d work on making the pro offerings better and unlocking unlimited distance measurement for free version.
Developer Response
Thanks for the honest feedback. I actually agree with you! Since I'm a solo developer, the Pro version is currently the only way to support my work and keep the app ad free.However, I am already working on more advanced Pro features. Once those are ready, I plan to unlock the distance limit for everyone in the free version. Thanks for your patience and support!
Fixed a bug affecting partial metering on certain iOS versions.
