### 2/5 — Regret using app to log dives

*2026-05-30, version 4.4.3*

I’ve just return to my dive logs in the app to determine the weights I used last time, which I left in the notes. Now that the dive logs are frozen after being verified by a buddy, I’m unable to see anything more than the first two lines of the notes section, essentially rendering the information useless.

This is extremely disappointing and will force me to recalibrate my weights and play the guessing game again.

How did this ridiculously obvious issue get past QA functional testing??

### 1/5 — Annoying app

*2025-03-29, version 4.0.8*

App wouldn’t open at dive shop to show certification despite being on Wi-Fi. Using the dive logs was annoying as some dives wouldn’t save and others I couldn’t update. Using my dive card and paper logs are WAY easier than this subpar app.

### 1/5 — Won’t load

*2025-03-06, version 4.0.8*

Won’t load at all. Just a white screen

### 1/5 — APP não encontra minhas certificações com a NAUI

*2024-11-24, version 4.0.8*

Simplesmente não serve para ver as certificações, que consigo ver no site brasileiro da NAUI

### 1/5 — Fix logging!

*2024-07-14, version 4.0.7*

Same issue as many others have stated, unable to save a log

### 2/5 — Dive Log Issue

*2024-07-04, version 4.0.7*

The app won’t let me make edits to my dives in the dive log. When I go into a dive to edit, the save icon stays greyed out. When I tap X to close it asks me if I want to save. When I click yes, it just spins and locks up and I have to close the app down. When I open the app back up the edits are not there. iOS 17.5

### 2/5 — Won’t let me log in new dives

*2024-05-06, version 4.0.7*

I did not dive for almost a year and the app won’t let me save new dives. It just gets stuck after I try to save.

### 1/5 — CRIAR CONTA

*2023-12-29, version 4.0.6*

Impossível criar uma conta no aplicativo

### 1/5 — Can’t log in

*2023-08-25, version 4.0.3*

Not able to log into the app, but able to log in on desktop. Emailed about this complaint and received no answer or help.

### 3/5 — Feature requests

*2023-07-10, version 4.0.3*

Like the app, especially the planning tables. A few suggestions/requests

1. It would be good to have the same info on the app as the NAUI dive logs (physical version). This includes visibility, surface and water conditions, etc.
2. It would be good to have some way to enter gear info so it is personalized
3. It would be good to have a way for a dive buddy to verify via QR code.
4. Integration with a dive computer so dive logs can be imported
