### 5/5 — Very handy app, with minor bugs

*2026-07-25*

Overall a very useful app, especially with the d2r release. The grail tracker is quite buggy though. I’ve had many cases where items previously marked as found just become not found after a while, which is really annoying. I hope the developer can get this issue fixed soon!

### 4/5 — Overall, pretty good app.

*2026-07-05*

Overall a great app. I love the Terror Zone reminders. In offline mode, occasionally the app doesn’t match what is in the servers. This has happened almost every time when the app says “The Pit” is going to be terrorized, it ends up being the Jail/Barracks in offline mode. Everything else I’ve enjoyed about the app.

### 5/5 — Simple and effective

*2026-06-20*

Easy to navigate, great extra features that you wouldn’t expect, has everything you need. Perfect sidekick app for the game. Been using it since it came out.

### 5/5 — Removed rune words

*2026-04-28*

The app is amazing, however you need to remove mosaic rune word, as blizzard has removed it from play.  Unfortunately I found that out after making it following your guide.

### 3/5 — Not worth it

*2026-04-04*

Most of the information here is available online.  I am concerned that it keeps pushing me to download “updates” in the app that are not coming through the app store.  Uninstalled.

### 1/5 — Awful

*2026-04-03, version 7.2.2*

The drop calculator is completely incorrect. There are missing items. The unique item list isn’t in alphabetical order and you can’t sort it. Waste of coffee money.

### 2/5 — Needs updating

*2026-03-17*

It looks like it used to be a good app, but with a lack of updates, it’s not any different th free ones. I want my 4$ dollars back. It looks well organized and the recipes look helpful but they only added some of the new stuff and they haven’t updated in years. Most instance the drop calculator tracker doesn’t have a terror zone option. These types of issues make it seem like it hasn’t been updated in awhile

### 1/5 — Buggy mess

*2026-03-02, version 7.0.1*

Terror zone no longer works. As well as app support link to report.

### 5/5 — Super

*2026-02-26, version 7.0.1*

Potrzebowałem prostego programu w którym wprowadzę swoje runy, a ten powie mi jakie słowa mogę ułożyć. Dostałem go. Działa. Jestem zachwycony. ;)

### 5/5 — Nice app

*2026-02-25, version 7.0.1*

If u like d2 worth to but this app its usefull 🫡
