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. -- Skeeterpot, 2025-03-29 ### *---- "Won’t load" Won’t load at all. Just a white screen -- Mel97b, 2025-03-06 ### *---- "Fix logging!" Same issue as many others have stated, unable to save a log -- Ivan8115, 2024-07-14 ### **--- "Dive Log Issue" 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 -- RunMad, 2024-07-04 ### **--- "Won’t let me log in new dives" 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. -- Que Viva Colombia, 2024-05-06 ### *---- "Can’t log in" Not able to log into the app, but able to log in on desktop. Emailed about this complaint and received no answer or help. -- mewolf11, 2023-08-25 ### ***-- "Feature requests" 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 -- GiriC29, 2023-07-10 ### **--- "Certificate number" When I try to view my certificate number, the app tells me to turn the phone to landscape to view it. When I do this, nothing happens. I’ve deleted the app and reinstalled it. How do I view my certificate number? -- Need my certificate #, 2023-06-05 ### *---- "Doesn’t work" Doesn’t populate with login -- Pabloctity, 2023-03-29 ### ***** "Incredible!" Absolutely incredible app…far exceeds anything offered by any other dive organization! -- Johan the Diver., 2023-01-29 ### *---- "Scam" They will charge you $10 per card to add previously earned cards to the app. -- Shopping Attorney, 2022-08-09 ### *---- "Beyond Useless!" While I love NAUI as a diver training organization, this app doesn’t reflect the quality of the organization at all. There was no way for me to access any of my dive training certifications— which is primarily why I wanted the app in the first place, or to locate local events and trainings relevant to me. Only international training and events show up. All I could enter was my name and address. There wasn’t even an area where I could enter my certification numbers for easier lookup and confirmation. I just got the eternal spinning wheel to nowhere. -- Bev53, 2022-03-07 ### *---- "Can’t login" I have an existing profile on Naui.org but I have never been able to login using the mobile app. -- lgfhjcvtf, 2021-09-29 ### ***-- "Dive Log information changes after closing app" When I log a dive in the dive log section and go back to check it later information has changed. The start time changes and the dive site field changes as well. Done know what is wrong with the app but it makes the dive log portion unreliable. -- kevin 327, 2021-07-14 ### *---- "Can’t select United States on account setup" On an iPhone X when setting up an account the US is behind the camera thing at the top and isn’t able to be selected. -- Thatguy38, 2019-12-25 ### ***** "Very useful" Great app to be able to access certain and other information on the go. Surprisingly user friendly and seemingly very well designed. -- thisnicknameistaken55, 2018-11-17 [View all NAUI reviews and detailed analytics on AppTail](https://apptail.io/account/signup?utm_campaign=ai-crawl&utm_content=reviews) ## NAUI Discovered Keywords - naui ## Apps Similar to NAUI - [UCF Mobile](https://apptail.io/app/ucf-mobile-Vrvc/united-states) - [University of Florida](https://apptail.io/app/university-of-florida-Uadd/united-states) - [Tennessee](https://apptail.io/app/tennessee-pzed/united-states) - [PADI Training](https://apptail.io/app/padi-training-dBwd/united-states) - [Seabook: Fish Identifier & Log](https://apptail.io/app/seabook-fish-identifier-log-JBId/united-states) - [Liberty MCCS Okinawa](https://apptail.io/app/liberty-mccs-okinawa-pMAe/united-states) - [Monroe County Sheriffs Office](https://apptail.io/app/monroe-county-sheriffs-office-wcXe/united-states) - [CSUMB MyRaft](https://apptail.io/app/csumb-myraft-HVbf/united-states) - [DEMA Show Mobile App](https://apptail.io/app/dema-show-mobile-app-dScg/united-states) - [EV Rescue - Electric Vehicles](https://apptail.io/app/ev-rescue-electric-vehicles-XKvl/united-states) ## NAUI Available In - [United States](https://apptail.io/app/naui-Cipf/united-states) - [Hong Kong SAR China](https://apptail.io/app/naui-Cipf/hong-kong) - [Brazil](https://apptail.io/app/naui-Cipf/brazil) - [Taiwan](https://apptail.io/app/naui-Cipf/taiwan) - [United Arab Emirates](https://apptail.io/app/naui-Cipf/united-arab-emirates) - [Canada](https://apptail.io/app/naui-Cipf/canada) - [Malaysia](https://apptail.io/app/naui-Cipf/malaysia) - [Australia](https://apptail.io/app/naui-Cipf/australia) - [Mexico](https://apptail.io/app/naui-Cipf/mexico) - [United Kingdom](https://apptail.io/app/naui-Cipf/united-kingdom) - [Saudi Arabia](https://apptail.io/app/naui-Cipf/saudi-arabia) - [Sweden](https://apptail.io/app/naui-Cipf/sweden) - [China](https://apptail.io/app/naui-Cipf/china) - [Switzerland](https://apptail.io/app/naui-Cipf/switzerland) - [South Korea](https://apptail.io/app/naui-Cipf/south-korea) - [South Africa](https://apptail.io/app/naui-Cipf/south-africa) - [Egypt](https://apptail.io/app/naui-Cipf/egypt) - [Indonesia](https://apptail.io/app/naui-Cipf/indonesia) - [Czechia](https://apptail.io/app/naui-Cipf/czechia) - [Netherlands](https://apptail.io/app/naui-Cipf/netherlands) - [Norway](https://apptail.io/app/naui-Cipf/norway) - [New Zealand](https://apptail.io/app/naui-Cipf/new-zealand) - [Peru](https://apptail.io/app/naui-Cipf/peru) - [Philippines](https://apptail.io/app/naui-Cipf/philippines) - [Portugal](https://apptail.io/app/naui-Cipf/portugal) - [Russia](https://apptail.io/app/naui-Cipf/russia) - [Thailand](https://apptail.io/app/naui-Cipf/thailand) - [Türkiye](https://apptail.io/app/naui-Cipf/turkey) - [Singapore](https://apptail.io/app/naui-Cipf/singapore) - [Austria](https://apptail.io/app/naui-Cipf/austria) - [Azerbaijan](https://apptail.io/app/naui-Cipf/azerbaijan) - [Belarus](https://apptail.io/app/naui-Cipf/belarus) - [Chile](https://apptail.io/app/naui-Cipf/chile) - [Colombia](https://apptail.io/app/naui-Cipf/colombia) - [Germany](https://apptail.io/app/naui-Cipf/germany) - [Denmark](https://apptail.io/app/naui-Cipf/denmark) - [Dominican Republic](https://apptail.io/app/naui-Cipf/dominican-republic) - [Spain](https://apptail.io/app/naui-Cipf/spain) - [Finland](https://apptail.io/app/naui-Cipf/finland) - [France](https://apptail.io/app/naui-Cipf/france) - [Greece](https://apptail.io/app/naui-Cipf/greece) - [Ireland](https://apptail.io/app/naui-Cipf/ireland) - [Italy](https://apptail.io/app/naui-Cipf/italy) - [Japan](https://apptail.io/app/naui-Cipf/japan) - [Kazakhstan](https://apptail.io/app/naui-Cipf/kazakhstan) - [Lebanon](https://apptail.io/app/naui-Cipf/lebanon) - [Nigeria](https://apptail.io/app/naui-Cipf/nigeria) --- ## About AppTail [AppTail](https://apptail.io) is a mobile app intelligence platform providing app analytics, ASO (App Store Optimization) tools, keyword tracking, competitor analysis, revenue estimates, and review monitoring for iOS App Store apps.
