## What is Limnia?

Limnia keeps track of your aquarium so you can enjoy it.

Record the water, the livestock and the maintenance, and let the app warn you before a small oversight turns into a problem.


ONE PURCHASE, NO SURPRISES

• No subscriptions, no monthly fees.
• No ads and no in-app purchases.
• Buy it once and it is yours.


YOUR DATA IS YOURS

• No user account. No sign-up. No password.
• Limnia makes no internet connection: there is no server to send anything to.
• Zero analytics, zero advertising, zero tracking.
• Photographs are saved without their GPS location or metadata.
• Works on a plane, in the basement, and with no signal at all.


THE WATER, UNDER CONTROL

• Record pH, temperature, ammonia, nitrite, nitrate, hardness, salinity and more.
• Set your own normal and critical ranges, per tank.
• Charts over 7 days, 30 days, 3 months or a year.
• Alerts when a value leaves the range you set.

READ YOUR TEST STRIPS WITH THE CAMERA

• Photograph the strip and Limnia suggests the values.
• Save your brand's colour chart once and reuse it.
• It is a rough estimate, and the app says so plainly: it never replaces reading the strip with your own eyes.


80 SPECIES WITH REAL DATA

• Fish, plants and invertebrates for fresh, salt and brackish water.
• Temperature, pH, adult size and honest minimum litres — not brochure numbers.
• Compatibility notes written to tell you what can go wrong.
• Limnia compares the species with your tank and tells you if it fits, without inventing what it does not know.


NEVER MISS A WATER CHANGE AGAIN

• Maintenance routines at whatever frequency you choose.
• Reminders on your device, with no notifications from any server.
• A history of what was done, snoozed and skipped.


ALSO

• Notes with photographs: your aquarium logbook.
• Equipment records, with installation dates and servicing.
• Full backups that you store wherever you like.
• iPhone and iPad, with a sidebar on the big screen.
• Six languages: Spanish, English, French, German, Italian and Portuguese.
• VoiceOver, Large Text and dark mode.


WHAT LIMNIA DOES NOT DO

It does not diagnose disease or prescribe treatment. It compares your data with published ranges and warns you; the decision, and a vet's judgement when one is needed, remain yours.

One more thing: never release an animal or a plant into the wild. Limnia reminds you on every species entry.
