It's OK, does what it says. No good for logging more than one tank, not possible. Also really irritating if you mess up the second photo because you can't click back and retake it, instead it just resets the whole test. Would be nice if it also worked for the ammonia test strips. To be really worthwhile there needs to be a way to view all the saved data better, maybe a graph vs time?

Very easy to use, but when you save the results it should show the time, not just the date, because if you so several tests in a day, after a partial water change etc, it can be quite confusing, which test it which, when they all have the same date and they look exactly the same. otherwise it is a fantastic, easy to use and very accurate water quality tester. Many Thanks

Great little app, 5 stars from me. The Tetra test strip and app combination are by far the quickest, easiest and most reliable way to test your water. Just be sure the lighting environment is stable and the green boxes are aligned correctly on test strip and your readings will be accurate everytime. The most recent update has improved the ability to examine previous test results for comparison easily, you can now also add more than one tank.
