### 1/5 — Won’t work

*2025-12-30, version 1.3.0*

DO NOT BUY, benchmarks stopped loading. Absolutely ludicrous to charge so much for PUBLIC information in the first place.

### 1/5 — Worked one day..

*2025-11-26, version 1.3.0*

Now won’t load any markers. $29 down drain!

### 1/5 — No options priced wrong.

*2025-05-24, version 1.3.0*

Price said $29.  It charged me $44. They are not clear on what the app will do. To see anything you have to be zoomed in close on the map for something to show up. There very little information given and there’s no way to mark that you’ve found the marker. Do not buy.

### 5/5 — Great app. Just what I needed. Work the money

*2022-10-16, version 1.2.7*

The title says it all. This is really a great app. I got every penny’s worth of what I paid. I’m a Geocacher who has always wanted to be more into benchmarking but there’s no easy way to pull up a datasheet in the field, and this app solves it all. Thank you to the creators for putting this together. I am giving a very rare and well deserved 5 star.
