## Most critical reviews (8 lowest-rated)

### 1/5 — Readability Poor

*2023-12-22*

The app only lacks a more readable user display.  The llight characters on a light background are very hard to read.

**Developer response:** Please update to version 2.0 with a completely redesigned interface, with several screens that facilitate the use and visualization of data. Added precision and funcionalities.

### 1/5 — Doesn’t work. iOS 16.1

*2022-11-08*

Doesn’t work. iOS 16.1

**Developer response:** We have just released version 1.3.5 which fixes the problem. Please update the application.

### 1/5 — 5 crashes in 1 minute

*2022-11-02*

Purchased the app and gave it a try, iPhone 13 Pro with iOS 16.1.

Didn’t fetch time or location, and tapping into the fields to enter data manually abruptly ended the app, repeatedly. Obviously, not updated on the newest OS version. I‘m asking for my money back!

**Developer response:** We have just released version 1.3.5 which fixes the problem. Please update the application.

### 1/5 — Won’t open

*2021-07-18*

App won’t open on iPhone 11 with OS 14.6.  I want a refund!

**Developer response:** The issue has been corrected. Please update to version 1.3.0

### 1/5 — Not worth the money

*2021-03-14*

Took a chance and found it wasn’t worth the money. Zero instructions and no support via the app or on the developer’s website.
Spend your money on something else.

**Developer response:** Please upgrade to version 1.2. User guide and support have been added.

### 5/5 — V2 Update

*2024-10-12*

Excellent upgrade.  Very easy to understand with some great new features.  I highly recommend this app.

**Developer response:** Please update to version 2.0 with a completely redesigned interface, with several screens that facilitate the use and visualization of data. Added precision and funcionalities.

### 5/5 — Latest Update - Big Improvement

*2024-10-01*

Replaces the need for your physical almanac. Gives you all the data you need to calculate your LOP.

### 5/5 — Sorry and please cancel my previous message

*2022-02-05*

Dear support,

Kindly ask you cancel my previous message and sorry. Before your apps doesn’t work properly. Now all works perfectly. Thanks.

**Developer response:** Thank you very much for your update. 

Best regards
