Really helpful app for new fish keeper

I like this for a lot of reasons, it’s a great way to keep my testing logs organized. I appreciate a way to track all the plants I have added and my livestock in one place. I love the advice I’m getting with my test results and fertilizer dosing. I am still exploring the app and finding new things.

Game changer for fish nerds

It had been maybe 8 years since I had an aquarium. This app has been a life saver for me. I’m doing a fish in cycle so I’ve been checking my water parameters daily. This app helps keep me organized and helps track my stock. It’s definitely worth the money.

Cheers Mate! Thanks and hope you enjoy it...

Cool App - But buggy, and not very intuitive

This app is quite cool , I like where it’s going, but it seriously needs to be polished. There are some buggy features , for instance, the AI overview tells me my nitrites have spiked when I’ve recorded 0 nitrites. Some buttons are redundant, like journal log can also be a water test, and you can scan water test, or navigate to another tab in the app and log the water test manually. This leads to some major confusion about what features are in what part of the app, it is quite easy to find a feature, and then totally forget how to navigate to it again. It took me a while to find out how to update my equipment or modify my tank inhabitants.

I do quite like the time series plot for water parameters. I would not pay for a subscription to this app until it becomes more polished and the bugs worked out, but I think it is well on its way there.

Response from developer

Thank you for the thoughtful and detailed feedback. You’re right that AquaLens needs clearer navigation and more polish. I’m evolving the app quickly based on user feedback, which has sometimes resulted in features appearing in multiple places while I gradually move functionality into improved workflows. I’m actively consolidating these paths and making equipment, inhabitants, and water-test logging easier to find. The incorrect nitrite-spike warning is especially concerning, and I’m investigating it. AI insights should always reflect your recorded data accurately. I’m glad you’re enjoying the water-parameter charts, and I appreciate you recognizing AquaLens’ potential. Feedback like this helps me prioritize the improvements needed to earn your subscription.
