They keep making updates, and they keep giving us more and more layers that we don’t use, causing more crashes and lagging, while completely ignoring the people who actually use the app screaming at the top of our lungs what we actually need. And then when we complain about this they say it’s “user error”. But when the entire industry is having the same issues it’s not user error it’s improper programing and maintenance. ### 1/5 — Terrible. Costing PGE millions of dollars *2026-04-03, version 3033.25350.2.8* I’ve used 4 similar apps over the course of my job, and this is by far the worst. Errors, crashes, lag, you name it. The switch to this program means it takes us approximately twice as long to do our job, which means it’s costing PGE (Pacific Gas and Electric) twice as much to run our program, which means the customers are eating it as rate increases. The only thing That annoys me more than this app is PGE’s decision to adopt it. ### 1/5 — Stake Holder Slop *2025-12-04, version 3033.25162.12.0* 👏👏👏 so glad that your stake holders are happy. Screw the guys in the field I guess. There is nothing “fix” this application besides scrapping it. Maybe we should use an already functioning application…oh wait can’t micro manage as efficiently. If I did this bad a job at my job I would be fired and blacklisted. ### 1/5 — The worst *2025-10-23, version 3033.25162.8.2* Just a terribly optimized and horribly executed map. I just might be better off using a paper map and a notebook. Everytime I have to use this app I legitimately want to rip my hair out. ### 1/5 — An awful replacement for Collector/Field Maps *2025-09-02, version 3033.25162.8.2* Why are the prescriptions and veg points separate data points? Why does everything take a gazillion years to load? It almost seems as if a focus group sat down to design the most user unfriendly, unreliable GIS app imaginable. The interface will strain your eyes, nothing makes sense. It may have been designed by a room full of chimpanzees sitting at computers randomly hitting keys. ### 1/5 — Sloth pro *2025-08-14, version 3033.25162.8.2* Always seem to have issues ### 1/5 — Worst mapping app ever *2025-08-13, version 3033.25162.8.2* Crashes all the time and is super slow. Takes up a monumental amount of storage space. Do not use if you have a choice! ### 1/5 — 0 star review but 1 star is the lowest option. *2025-08-04, version 3033.25162.8.0* By far the worst mapping app I have ever used. GPS inaccuracies, frequent data loss and more. If you’re looking for a mapping application that will compromise your production then you have came to the right place but your GPS is off by about 30 feet. ### 1/5 — Don’t try to run this on an older phone or iPad. *2025-07-31, version 3033.25162.8.0* They’ve been working hard to make this app stop crashing for years, and it’s finally at the point that most days it won’t crash. However, that effort resulted in an app that makes the phone run extremely hot, causing it to slow down so much that it takes minutes to do something that should take seconds. ### 1/5 — No. Just no. *2025-07-31, version 3033.25162.8.0* Complicates what should be simple. ## Frequently asked questions about Lemur Pro ### What does Lemur Pro do?
