### 5/5 — Highly recommended

*2024-11-21*

Great resource

### 4/5 — I like it

*2024-09-27*

Pretty good. Ads are non-intrusive, which is great. It’s a good quick reference for when I’m on the go. 

Only thing so far that I wish it had was the option to copy the 1.9 thread promotion messages with the placements and required fps like foe.tools has.  Not having that feature has made crafting such messages by hand very difficult on mobile, so more often than not I just wait until I’m home to do it on my desktop, which has caused my usage of this app to decrease. If that feature could be added, I’d probably be using it more while I’m on the go.

### 5/5 — Easy, helpful app

*2023-09-23*

The title pretty much says it all.  This is now my “goto” for quick reference on my GBs upgrade path.    I love this little app.

### 5/5 — Useful app

*2023-05-26*

Helps

### 5/5 — Works just perfect.

*2022-08-29*

Great tools and very handy

### 5/5 — Very helpful

*2022-08-14*

I like this app. It is very useful and has helped me level several great buildings faster.

### 2/5 — Needs copy and paste

*2022-01-23*

If this app had a copy and paste feature it would be more useful. I’m sticking to FOEtools

**Developer response:** Hey, thanks for your feedback. Copy and paste feature has been introduced in the latest version of the app. I encourage you to revisit the app and reassess :)
