With transparency
Acuario Manager is new, so let's get straight to the point: this is what it really offers, without fine print or inflated promises.
Fish, corals, plants, and invertebrates with information sheets, photos, and compatibility warnings. The photos are from Wikimedia Commons under a free license, and their authorship is credited within the app.
The app and this website are translated into 106 languages so you can use it in yours, wherever you are.
It doesn't need internet for the essentials. Your data is stored on your device; it's only synced if you create an account to transfer it to another mobile device.
Your measurements, photos, and records live on your device. Start using it without an account; the account is optional and is only used for cloud backup.

How it works
The state of your aquarium as soon as you open it: how many parameters are within range, what is at the limit, and what is happening.
Tap a parameter and see its evolution by week, month or the entire history, with minimum, average, maximum and oscillation.
Your population with a profile and photo of each species. When you add a fish, coral, or plant, we'll alert you to potential problems before they occur.
No cloud or API keys required: respond with your own measurements, tasks, and residents. Fast and private.
How much salt for your water change, how much KH, calcium, and magnesium to dose for your volume. No manual calculations.
Save a photo every so often and see how your aquarium matures, with the date of setup and a before-and-after comparison.
