Limnia: Aquarium Care Log

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.
