### 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.

### 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.

### 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.

### 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)

### 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

### 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.

### 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

### 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
