## Most critical reviews (8 lowest-rated)

### 1/5 — Not helpful

*2019-05-05, version 2*

Thought it would give dosing based on ammonia, nitrite and nitrate readings but only gives same dosing instructions as bottle.

### 2/5 — Ok but...

*2019-09-22, version 2*

It’s ok but I can’t get it to work with my camera, or my calendar. Also the reports are not easy to read. 
I’m looking for something that will tell me at a glance when I last did a water change, and which of my tanks are due, or especially overdue, for a water change.

### 2/5 — Needs to be updated new aquavitro products!

*2016-04-11, version 2*

I just downloaded this app and was hopeful it would help calculate the doses of nutrients for my new tank. I hope it will be updated with the new product line soon.

### 3/5 — Nice app but needs improvement

*2023-05-19*

It would be great if all the Seachem products were available in the app to help with dosing of aquariums.

### 3/5 — Good, but needs work.

*2020-06-27*

When using the calculator for acid and alkaline buffers, it tells you to add a negative amount. I’m assuming this is wrong?

Love my seachem products tho!

### 4/5 — Gh and kh

*2020-07-25, version 2*

A simple correction is to make the dosing available in dkh and dgh since this is the most common units used in all API tests

### 5/5 — Great app

*2016-09-14*

This is a wonderful app for recording your day to day parameters and also dosing recommendations well worth the download !!!!!! Thanks seachem !!

### 5/5 — Nice app

*2015-08-08, version 2*

Very convenient app, no need computer to calculate dosage. Please add dKH or PPM option.
