Working well now. ### 2/5 — A little disappointed. *2018-05-16, version 2.3.3* I got this app to help my 11 year old son track out new tank. I especially got it for the reminders that are shown to be able to add. Well I can’t add reminders, and there is little to nothing more than I can get from a free app. ### 4/5 — A few remarks and suggestions! *2016-01-26, version 1.8.3* First of all, this app rocks congrats on a very informative app and visually pleasing app! Some remarks and observations below: - fish disease and remedies and medications - setup photos or videos on how to layout rocks, corals and frags. - reef monitoring equipment and devices - dosing pumps and common doses per unit water volume I have a lot more ideas but let's see if these ones are doable and I will share more ! Thanks again and good luck ! ## Most critical reviews (10 lowest-rated) ### 1/5 — Waste of time *2025-02-06, version 3.0.17* The app is useless. It keeps locking up and freezing. I have lost weeks of tests and notes. ### 1/5 — Used to be great… Until the awful redesign *2023-12-14, version 3.0.10* Use to be a great app until the awkward redesign, with parameters on cards that have to be jerkily scrolled through to access, rather than them all being on one screen. PLEASE bring out a classic view option soon, as I am now stuck with a couple of years worth of data on a clunky & awkward app. ### 1/5 — Prefer old UI *2023-10-26, version 3.0.6* The new UI doesn’t feel as intuitive as the previous versions I’m use to. ### 1/5 — Crashing *2020-04-16, version 2.8.6* Accidentally added two tanks in setup. When I go to delete one, it crashes the app each time. ### 1/5 — Marine box *2020-04-04, version 2.8.6* A lot of issues!!!! ### 1/5 — ehhh *2020-02-10, version 2.8.4* waste of money if you ask me, you can google all of this stuff. i thought this app would be cool and interesting, good ideas but needs work. ### 1/5 — Data lost *2019-12-14, version 2.8.2* After 6 months monitoring my reef all data disappeared. The support do not solve my problem. I do not recommend. ### 1/5 — All data gone *2017-04-25, version 1.9.1* iPhone 7 running 10.3.1 and after the update, two years of data gone. My Tank not available, only the option to create a new one. A year and a half of data all gone. Do not update! ### 2/5 — App Problems *2025-04-14, version 3.0.17* No ability to write notes. Reminders portion does not work correctly and it will not allow repeat reminders activate. Instead the app shuts down. No response from developer from questions asked. ### 2/5 — There is no cloud save *2021-10-30, version 2.9.10* There is no cloud save like it says that is the reason of me buying this app but what i add on my iPhone i can’t see it on my iPad when i open the app on it. Disappointed ## Most praised reviews (10 highest-rated) ### 5/5 — Love it. Can love it more *2021-11-04, version 2.9.10* Great app. Couple of things I would love to see. Adjust tank water volume, as it calculates volume when you add a tank but can’t change the volume to account for sump, sand and rocks Snapshots aren’t saving Ability to chose preferred range for parameters, especially Alk. I run at 11 dkh and it is off the graph. In Alk, auto convert entries. So if I test at ppm I don’t have to open the calculator to convert to dkh Stock solution dosing calculator. Ie using Redsea B stock solution instead of the powder calculation(or 1/3 b liquid) ### 5/5 — Responsive developer and great app *2021-04-16, version 2.9.7* I use this app to log all my tanks nitrogen cycle progress and keep track of other parameters. It’s great. Also there was a minor bug in the app and I dealt with the developer directly and they had it fixed within a week. They were communicative and persistent in solving the issue. Well worth the money to have a convienient app like this at my finger tips to track my water parameters and other things. Highly recommended app to enhance the hobby. ### 5/5 — Feedback *2020-08-14, version 2.9* Why no Seachem 2 Parts? Just added the app and am trying to set it up for my reef ### 5/5 — I love this app *2019-10-09, version 2.8.1* Best salt Water app ever 👍🏾 ### 5/5 — Decent app *2019-05-01, version 2.8* Many apps for recording data for marine fish can be quite expensive or poor if free. This app for a small fee performs quite well compared to free ones. I would like to see a few more tweaks to make it even better. Perhaps option to add price, date and place of purchase for equipment, Corals, and livestock. Also the ability to select the range for parameters when testing. The conversion section is very useful. ### 5/5 — A melhor e mais completa calculadora para o reef *2018-05-24, version 2.4.3* De todas as ótimas funcionalidades do app, o destaque fica com os logs e a calculadora. Sem falar que o suporte prestado pela equipe é rápido e preciso. Parabéns ### 5/5 — 10/10 *2018-03-30* Great app and top developer listens to what his customers want and implements it Anyone with a reef tank this app is perfect and good value keeps all you need in one spot! Thanks ### 4/5 — Can’t seem to sync with other devices *2021-11-06, version 2.9.10* This app definitely has potential. I started it on my iPad, but I can not get any information to transfer to my iPhone for the life of me. When I try to share it, it doesn’t really do anything but open it on my iPhone. Other than that, it is a pretty good app. Holds a lot of info. ### 4/5 — Marine box *2021-02-27, version 2.9.6* Very good app you can keep up on your parameters look back on the parameters the only thing that may be confusing when you calculate for supplement it doesn’t tell you if it’s weekly or daily ### 4/5 — Seems great so far *2019-08-28, version 2.8* I’ve only been using it for a couple of days but so far I really like it. The only thing I haven’t figured out is how to do recurring reminders. Is that possible? If not, the reminders are less useful. Could totally be user error here. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
