Still a great and reliable app for saltwater aquarium hobbyists
I took a break from the hobby after my tank crashed in 2022. Only recently got back into it, and I'm so glad that the app is still functional.
Waste of money
Doesn’t save any of my testing days. I am currently cycling and can’t compare my days. 😡
Fantastic app with some minor issues
First of all, I just want to say this is the best app I have found for tracking parameters as well as keeping information on all of my tanks. One of the biggest issues I found with other apps is that they only let you have one or maybe two aquariums able to be stored or if you have more they make you pay. As we aquarists know we typically have at least two, probably more tanks, so this app caters to us. The first issue I have with this app is probably something they could fix and it’s the default parameters that appear when you go to log them. Only nine parameters are showing at any one time and if you want to see other ones, you need to change which ones appear. It’s unfortunate that ammonia and nitrite are set to default to appear since most people don’t commonly check them. Every time I want to check/see my phosphate levels I need to go under the visibility filter and swap out either the ammonia or nitrite and then select phosphate in its place. Kind of annoying because it’s something I have to do multiple times a week. If they let us change the default parameters, this issue would be solved. The only other minor complaint I have is under the databank of fish and corals sometimes they don’t have what I’m looking for. They just need to have an update where they include more fish, coral, and invertebrates. Overall, the app is pretty fantastic and worth the minor charge for it. I never pay for apps, but this is one that I am glad I purchased.
Does not live up to hype
I was expecting so much more, compatibility of specific species of fish and inverts, recommended tank sizes, dosing recommendations. This is simply a tracking tool with limited encyclopedia of livestock. A paid app should offer more than, “Not much is known…”
Measurements
Is there a way to switch from liters to gallons?
Great App
Amazing app with all the bells and whistles I need. Would it be possible to get landscape for this app as I use it on my iPad?
Crashes
Installed then tried to setup an aquarium. After saving aquarium info tried to click on aquariums to view and app crashes and closes. Tried uninstalling app and reinstalled but same thing. Useless app I paid for.
Beautiful App
I actually love this app and the look is so much more modern and friendly than other alternatives. I just wish so badly I could share and access the data across multiple devices. When I test the tank I want my boyfriend to see results on his phone and when he tests I want those records too. I don’t know why but this is something all of the best thank management apps seem to be missing. I mean, it’s 2023 people… love the app though.
Pointless
I purchase this app thinking it would be a nicer UI vs AquaticLog which I’ve been using since I set my tank up. So I had my iPad out trying to enter the info from AquaticLog to Pocket Marine. Phone died so I went to use my iPad thinking it would just sync like AquaticLog and well let’s be honest almost ALL Apple apps thus the reason it has such an amazing following. So needless to say when I went into the app on my iPad there was nothing there. None of the info I had spent the last hour or so entering was in the Pocket Marine iPad app. So what exactly is the point of having it on both?
Okay, needs fine tuning
Some species of fish are missing and there is no way to contact the developer. I personally need black and white ocellaris clownfish
Not bad
It doesn’t appear as though you can change to imperial units? I can’t find a way to contact a developer. This would be a massive help to us goofs in the US lol. Edit: I’m an idiot. Thanks for the help!!
Unable to safe a aquarium
I’m allowed to input all information for new aquarium but when I go to safe it app shuts down and no aquarium saved. So unable to add livestock or test results.
Great App still needs some improvements
This is an awesome app! It tracks just about anything you would need or want to track. There are some improvements that would push this over the 4 stars -Test Diary:Allow users to set the “preview tiles” in the testing diary as a default view for them. I don’t test all the app’s’ default parameters and am forced to manually configure what I want to see as a “quick view” every time I enter test results - Test diary: graph is great. However it would be great to see multiple parameters as an overlay of each other to get a better view of balance. For example I’d like to see PO4 and NO3 to see how they correlate with each other in one graphic view. It would also be nice to have the ability for us to export to an excel spreadsheet as well Habitant diary: it would be awesome if we could enter the fish store’s name and info in our user database so when we do add new livestock, the “where purchased from” can be a drop down for frequently used shops instead of manually entering in info with different variances for the same store. Other than that, this is an awesome app. Thanks for making it!
App crashes when trying to set up an aquarium
I’m new to this app. I’m looking for something to help guide my water testing and maintain a record of results. App seems to be a good tool for this, and appears to have many useful features. Unfortunately, it crashes when I attempt to set up a new aquarium. As long as you track testing for only one aquarium, the crash does not affect the apps usefulness.
Decent
I genuinely like this app and the information that is provided within. However, there are an absurd amount of spelling mistakes. To me, that is just a little unprofessional and tacky, and sometimes I question the validity of the information given, due to the spelling mistakes. But overall, is a good app, I’ll continue to use it.
Great App but..
The app is amazing and full of great things but it’s missing the most important thing which to export data or at least being able to create an account to store all the data of tests, that way if you get a new phone you can import all your data, for now if you get a new phone you loose all your data which makes it useless. I really hope that this could be fixed ASAP!

Great app for reef/marine enthusiasts
This app is a great resource for new refers like myself. A great add to this would be to be able to add fish etc to an aquarium directly from the encyclopedia entry.
Avoid. Numerous bugs & usability issues.
Wow, really surprised a paid app that is so highly reviewed and has been around for many years is filed with so many bugs. I’ve used the app for a few hours and was left very frustrated. e.g. when trying to edit the targets / range of temps for viewing the trend graphs, and selecting say 75 degrees Fahrenheit for the low, it picks a random degree Celsius and then crashes. If you scroll the never ending list of values to finally reach 35ppt that starts at 11, it crashes. This is reproducible. Come on! It’s like no one actually uses this app or tested its UX. I can’t be the first app user who switches values from C to F or gets annoyed with an endless scroll for 5-10 seconds just to select 35, 34.9, or 35.1 ppt, every time. This app takes much longer than an spreadsheet or even paper and pencil. Lots of room for improvement; avoid for now.
Water Parameters seem off
The app looks good, but see some issues and not quite sure how to address. 1. If you enter a temp reading of 78.2°F, the indicator is Red, you you enter 25.6°C, the indicator is Green. Using any value of F does not change the indicator to Green. Using the the converted value of C to F does not work. 2. What values are used to indicate Red vs Green? This is not published anywhere on the app. 3. If ammonia levels of .25ppm is considered safe, why is my level of .04 showing up with a Red indicator?
Review
Loves this app!!! Please keep it updated!!
Poor
You can’t transfer data to a new phone which makes this app useless
Nice App
I really like this app. Has a lot of information on hand about different Inhabitance. It would be nice if we could turn off some test if you don’t use them so they don’t show up when you email. It would also be nice to be able to sync between multiple devices. Auto tank calculations would be a nice additional feature.
Improvements
Great app really helped me a lot however most of the information is on my I pad I’m unable to sync to my I phone and I’m not inputting test results and fish and coral stocks twice. Otherwise very useful tool
Loved app until 4 months of test results deleted
I have been loving this app since I’ve had it over 6 months. Just today, the app got rid of 4 months of test results for no reason. What is the point if glitches and deletes all of my saved tests and resets the default ranges.
Great Tool
Wish there was a way to share data between devices. Other than that it is a great tool to keep track of measurements and tasks.
Sådär...
Snygg och härlig app att använda. MEN... varför nollar den alla resultat man inte skriver in? Super störande. Man gör ju inte alltid alla test alla dagar. Så dem dagar när du hoppar över något test blir dessa reggade som 0. Löser dem detta så får den betydligt högre betyg då jag verkligen gillar den!
Add wish list!
Love the app, but hoping creators will add a wish list! I want to be able to favorite fish.
Great concept
I thought it would be more informative as far as species go. If you are getting it to help you with info on fish, coras, and other stuff you might want to keep looking.
Great app but needs an update
Great app, nice design and quite a handy app however, it is quite buggy. Everytime I try to edit targets (high/low) the app crashes and closes. Only 1 aquarium saved, yet it keeps asking to set which aquarium you are making changes to. If you only have one aquarium then it should default to that or not ask. Unable to edit/personalise home screen. Wish there was a way to track spending e.g. add price of products bought like sand/filter/dosing chemicals etc
Yesssssssssss!
Honestly I don’t have anything Major to complain about. The only thing I can say is it automatically assumes that you have a sump.
Fantastic App
What a great App for running a Marine fish tank. Easy to use and looks great. I hope a tropical version of this App is created as I run one of these too.
Love it, but have a question
Love this app and have been using since restarting (2 months) from a farrow tank of 2 years. Have been using the app to document tests, list fish wish list, and other important research. Can I sink my phone and iPad version? UPDATE: Quick response from developer that there is a plan to allow sincing between devices in the near future. Very satisfied here.
Shame previous feedback not acting on.
This app is ok, it can be a bit fiddly putting test results in. It keeps track of all your testing but shame the previous review wasn’t acted on as they are right, it would be useful to more easily compare today’s readings with previous days.
Worth it!
Really great app to help log, monitor, create a critters diary, and several other parameters of your saltwater system all in one place!
It is ok ... but solid value for money
I think it works ok and seems to track the info well I wish the graphing showed the target range so I knew If I was in or out of range And the directory of coral is not as good as I thought
Soft corals section crash
Soft corals section crashes
Need some help !!
How to change liter and temperature to gallon and Fahrenheit in the details page. I see an image in your website about us page where the blue tang picture shows in gallons and Fahrenheit but I don’t see an option in the app to change this setting. Excellent work on the app overall. Brilliant Design!!
Awesome app
Crashes on me when I got to soft corals
Good for basics
This app is good to keep track of inhibitants and aquarium maintenance. However, when you put in more than one of the same species of fish at the same time, it only shows up as one fish. Ex: my trio of scissortails only showed up as one fish even though I entered three on the quantity. It also doesn’t take into account the different fish of the same type in comparability. Ex. Wrasse are not compatible with wrasse. You don’t have an option to add what kind of wrasse and sometimes they are perfectly safe together depending on species. Good for basics. Not good for details. Hope this helps.
Good app but still room for improvements
After trying out all the available reef keeping apps I’m sure this is the one with the best UI and design, others look plain and outdated, but the thing is, I don’t get why the parameters shown on the main page can’t be changed all at once, there could be a default setting to choose certain parameters on the 9 squares, or just show the first 9 you record in. For me, I don’t usually test my NO2 and NH3, and it’s a bummer I have to change them to PO4 and something else all the time. Another thing is the graphs aren’t that easy to read, you need to drag and drag to find the right parameter and then drag once more to check out the whole timeline
Needs more fish species info... and needs a little editing.
The image for the Picasso trigger is incorrect. Would love to have more species in the information area. Like: Doryrhamphus excisus, strawberry crab, Monodactylus argenteus, Blue Ribboned Demoiselle, Halloween hermit crab... etc Also it would be nice to be able to see the full extent of the notes input in the inhabitants diary. And have the data be backed up some how in case of a phone crash (caused by dropping it in the tank accidentally.)
It’s not finished
Doesn’t have info on some popular species of fish and corals
