“I have to say i am amazed to see you actually changed what i suggested in my previous review, you have my respect! I tried many different apps but this one is absolutely the best for my reef tank”

Absolutely perfect app

“I reeally like this app. Has a lot of information on hand about different inhabitants. It would be nice if we could turn off some test if you dont use them so they dont 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”

“Its a good app. Worth the price. I only wish they had a settings page where you could change the dark background to white with black type. Its difficult to read in some light conditions”

Good but...

Brilliant App

“This app has been fantastic for keeping all of my test results! Great UI and simple to use. Two suggestions from me, currently you can editan individual dates results to reorder them but id like to be able to make the re-order happen across all of my results. Even using haptics to holds and drag to re-order would be better than individual scroll down menus. Secondly, the graphs for results have the latest results on the left running with the oldest to the right. Every graph and table we read runs left to right with the current result being on the right. Thanks and keep up the great work and updates!”

Great for record keeping!

I use the app lots of times when im in the LFS to check details for fish and others. Great database. One question: I use the app on my iPhone and iPad but data does not get transferred from iPhone to iPad (ie fish that was bought etc.) Is there a way to accomodate this? Keep up the good work!”

Great app anywhere

“Great app, very helpful as a beginner in marine side of things. All i would say is it would be a bonus if there was a way to sync between a couple of devices or do a log in for the diary etc. as i have it on my iphone and iPad and to update the list of what i have in the tank has to be done on each seperatelybut thats something that maybe in the future?”

Worth every penny

“Love this app and have been using since restarting (2 months) from a fallow tank of 2 years. Have been using the app to document tests, list fish wish list and other important research. Can i sync my phone and iPad version?

Update: Quick response from developer that there is a plan to allow syncing between devices in the near future. Very satisfied here.”

Love it but have a question

“The app is very helpful but when i click on the soft corals tab the app crashes

Edit: The developers were very helping in helping me fix the issue and now the app is fully functional. This app is a must have in terms of keeping track of your reef.”
