Tankside: Fish & Aquarium Care

Know how your tank is doing in five seconds. Tankside turns water tests into a clear answer and chores into reminders that actually fire. No account. No cloud. Nothing leaves your phone. WATER QUALITY, DECODED Log a test in seconds. Every reading is scored against a target range for your tank type, and the tank gets one status: in range, check this, or out of range. The tank scene tints with it, so you see trouble before you read a number. - 13 parameters: temperature, pH, GH, KH, ammonia, nitrite, nitrate, TDS, salinity, phosphate, calcium, magnesium, alkalinity - 5 tank types with default ranges: freshwater, coldwater, brackish, saltwater and reef, all editable - Ammonia, nitrite, nitrate and phosphate are never "slightly high": any exceedance is flagged - History charts with a target band and a trend ALERTS THAT EXPLAIN THEMSELVES An out-of-range reading raises an alert with a plain-English note: what the parameter is, what usually moves it, and what keepers commonly do next. Alerts do not stack: a second bad reading escalates the first, and a reading back in range resolves it. REMINDERS THAT SURVIVE A REBOOT Water changes, feeding slots, water tests and warranty expiry become notifications scheduled on the phone itself. They work offline, survive a restart and respect quiet hours. - Feeding schedules by time and weekday, ticked off with one tap - Recurring maintenance from daily to quarterly, or every N days - Logging a water change completes the matching task for you KNOW YOUR FISH A catalogue of 38 species and 16 plants with care ranges, temperament, tank size and group size, each with its own illustration. - Compatibility check before you buy: water type, temperature and pH overlap, temperament, fin-nipping, predation by size and every current tank mate - Groups, not just individuals: a shoal of twelve is one entry A LIVING RECORD Journal entries with photos and pinned notes. Equipment with warranties and service intervals. Per-tank statistics for water changes, maintenance time and spend. YOUR TANK, DRAWN Every tank is drawn, not photographed: an animated scene whose water carries the tank's status. Customise substrate, hardscape, plants, livestock and lighting, with 14 species, 10 decorations and 3 lighting moods. NO ACCOUNT. NO SERVER. NO EXCEPTIONS. Onboarding is three taps; there is nothing to sign up for. Your readings, notes and photos live in the app's private storage, and it works entirely offline: there is no online mode to fall back from. A backup is one file you keep where you like. There is no sync between devices: moving phones is a backup and a restore. FREE AND PREMIUM Free, for as long as you like: one tank, up to 10 living animals, water tests, alerts and guidance, reminders and feeding schedules, the catalogue and compatibility, the journal, equipment, the expense log, and 90 days of chart history. Premium adds unlimited tanks and animals, full chart history, expense insights, backup and restore, five extra accent colours and every decoration. The 90-day window is only a display limit: every reading you log is kept. SUBSCRIPTION Premium is an auto-renewable subscription, monthly (EUR 4.99) or yearly (EUR 39.99).
