### 1/5 — Can’t log in

*2026-04-16*

When I go to log in, the Validation Email link takes me to a “404 Page Not Found” screen. Would love to use it but it won’t let me.

### 5/5 — Amazing gene builder

*2026-03-22*

This builder was a life saver for when stories 2 came out years ago. I would love a stories 3 version with a gene builder environment skills as well

### 5/5 — Muito bom

*2026-03-16*

Perfeito

### 5/5 — 期待推出3代阿

*2026-03-08, version 1.3.1*

### 5/5 — 너무 감사합니다.

*2025-09-28*

계속 검색하다가 루리웹 댓글에서 이 앱 스샷을 봤습니다. 유전자 확률과 지도에서 몹 위치까지 너무 잘 해주셔서 유료도 질렀어요. 너무 감사합니다. 이제 크롬에 검색안해도 돼...

2025년이 된 지금까지도 너무 잘 쓰고 있습니다.
머리는 여전히 멍청해서 패턴을 외우지 못해 유용하게 잘 쓰고 있습니다.
감사합니다.

### 5/5 — A really great app

*2025-07-06*

This app is really great. Helps me plan my wacky builds and helps with gene placement optimization. I paid for the app. Just a dollar and some change. However, I’m a bit annoyed by this. You mean to tell me that EVERYTHING else in this app is free accept rate percentages??? Odd choice. Bold choice. Five stars otherwise.

### 5/5 — Muito bom

*2025-01-04*

Compatível com português, tem a lista de subquest e simulador com todos genes disponíveis

### 5/5 — 不曉得還有沒有更新空間

*2024-12-07, version 1.2.0*

但還是支持一下

### 5/5 — Love it! Very detail for getting monsties.

*2024-11-11*

I was wondering about this app. But it save all the time you need to search figure out what are their weaknesses and what not. I highly recommend on getting this app. It will be worth it to get it. Overall a great app.

### 5/5 — Worth to pay for full data

*2024-11-06, version 1.2.0*

Did try and it’s worth to pay.
