Really enjoy that you can create your own entrees as I get new fish, new coral, products etc. I keep everything tracked in here. Really makes everything easy to look back. Worth the few bucks ### 5/5 — Great app *2020-02-24, version 1.2.1* Very simple to use, allows for setting up multiple tank profiles, keeps a activity log, and input of pictures. Adding an event is simple and has alot of preset options or create a custom entry. ### 5/5 — Great App *2019-06-30, version 1.2.1* I’ve been using reef tank pro for about two years and keep records on three tanks. The thing I like most about the app is you can create custom types of data. As an example, I’ve created an entry for equipment purchases, equipment maintenance, fish purchases, water changes etc. you just have to use your imagination. ### 1/5 — Bad app *2017-02-27, version 1.2.1* No way to manually input the information for water test readings ### 1/5 — OK app *2017-01-26, version 1.2.1* There are no instructions on how to use this app. The app is OK but needs a lot more work to even make it worth while. It's basically a excel spreadsheet in a app form. Bad purchase in my end. Save your money and go with an app that is an it more user friendly. ### 5/5 — It's great *2014-12-16, version 1.1.2* I would obviously like to see iCloud sync, but it's not a requirement. This tracks the necessaries and that's what I need most. ### 2/5 — No Syncing with Other iOS Devices?? *2014-03-25, version 1.1.2* Would have given this app a 4-5, but an app these days that doesn't sync across your devices?? Really??? Maybe the author will step up and fix this issue. Like the app otherwise. ### 3/5 — It's ok *2014-02-24, version 1.1.2* For 5 bucks I expected a lot, I'm a little let down. The interface is not intuitive, although once you've used it for awhile it's easy enough. My biggest complaint is that you can (after much effort) export your data as a .csv file but can't import that file into the same app on a different devise. I use my iPad at home to record my system's parameters but would like to have my data available on my iPhone when I'm on the go. ### 1/5 — Should of saved my money *2014-01-31, version 1.1.2* Easier to write your information down in a book. Save your money buy a copy book. ### 5/5 — Good app *2013-10-08, version 1.1.2* I find this app works out great for what I'm wanting to do. It can be a little difficult if needing to go back far in dates but if you can keep up with the graph then it's pretty nice. Good purchase. ## Frequently asked questions about Reef Tank Pro ### What is Reef Tank Pro? Reef Tank Pro is an iOS application designed for tracking and logging aquarium water parameters.
