Ratings and reviews

Has helped to speed up my crane assisted tree removals. Generally in the summer months it is pretty close to spot on. For residential trees. The app is only a general estimate so it's accuracy is season dependent but that is expected. The summer months are very close in all the locations I've used it.

It used to be a great app until they switch to the pro and now everything is measured in inches not feet. Which doesn't make very much sense to me I'm a crane operator and I've used it for the last couple of years but no longer hopefully they will change it back to the original

I'd give it a 5 star if I was able to input log length in feet AND inches, not just inches. Having to use inches solely is an inconvenience I can do without.
