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.

Great if it Worked Properly

This app seems amazing at first, plenty of neat tools to help you out especially if your a beginner or newer to the hobby. I have 3 tanks and while trying to set up separate tank profiles for each one, the app does not allow me to enter filter, lighting, or even how large the tank is. Instead it keeps telling me to find “Hardware Specs” however I can’t find it anywhere. There’s a 99% chance I’m a moron tho so who knows.

Response from developer

Hardware specs is in my tank, click on more from the options at the top (where journal, care etc are), then click on Lab, then hardware specs. You can enter your lighting and tank specs in there. Each tank is set up separately so the analysis is separate for each tank. You can switch between tanks at the top of my tank (where the names are). that will also allow you to set up hardware specs for each tank. There is also guides in the library on how to set up the hardware and the rest of the app. If you still can't find it, I can walk you through it if you drop me an email Dave@aqualensapp.com

Super helpful for beginners

It’s a new app, that the owner listens to users and is making tweaks/adjustments. Simple and easy way to track the water chemistry of your tank. Health features use AI to analyze pictures of plants and fish to give a diagnosis.

Response from developer

CJ, thank you so much for the thoughtful review and for all of your incredibly helpful suggestions. I’m actively listening, and honestly, many of AquaLens’ newest features have come from your ideas. I’m glad the water chemistry tracking feels simple and easy to use, and I’ll keep refining the AI health tools for plants and fish so they get even more useful over time. Really appreciate you being part of shaping AquaLens.
