AquaKeeper vs ReefDrift

Track every tank. Catch problems early. Never miss maintenance. AquaKeeper is a clean, fast aquarium management app built by a hobbyist who was frustrated with existing options. No bloat. No outdated design. TEST KIT SCANNER Point your camera at an API, Red Sea, or Salifert liquid test kit. AquaKeeper reads the color against a reference card and logs the result for you — no more squinting at a color chart or typing numbers by hand. WATER TEST LOGGING Log pH, ammonia, nitrite, nitrate, phosphate, calcium, alkalinity, magnesium, salinity, and temperature. Beautiful charts show trends over 7, 30, 90 days or all time. Safe-range lines tell you instantly if a parameter is off. Tap any data point for the exact reading. HEALTH SCORES Every tank gets a 0–100 health score calculated from your recent water tests. See at a glance which tanks are thriving and which need attention — before small problems become expensive ones. SMART COACH AquaKeeper watches your recent tests, livestock, and tasks, then flags what actually needs attention — a KH that's been sliding for days, nitrate trending up, a water change running late. Plain-language insights land in your Today tab, not a dashboard you have to interpret yourself. LIVESTOCK TRACKER Log every fish, coral, and invertebrate with species name, purchase price, date added, and current status. Browse 200+ species with care guides, minimum tank size, temperature and pH ranges. Compatibility warnings alert you before adding a new inhabitant that may conflict with your existing livestock. MAINTENANCE SCHEDULER Create recurring tasks for water changes, filter cleanings, media replacements, and anything else your tank needs. The Today tab shows all overdue and due-today tasks across every tank in one view. Push notifications remind you before tasks slip. EQUIPMENT LOG Track pumps, lights, skimmers, heaters, and reactors. Log purchase date, price, and warranty expiry. Get highlighted warnings when warranties are approaching. See your total equipment investment per tank. PHOTO LOG Document your tank's journey. A photo timeline shows how your aquascape and corals have grown over months and years. Tap any photo for fullscreen view with pinch-to-zoom. iPHONE AND iPAD AquaKeeper works natively on iPhone and iPad — including a sidebar layout on iPad — with optimized layouts for both.

Log every reef parameter in seconds. ReefDrift calculates a Tank Stability Score — Stable, Watch, or Danger — the instant you save a reading. Catch a 0.3 dKH swing before it costs $500 in coral. No account. No cloud. Just your tank data, on your device. LOG THE BIG THREE AND EVERYTHING ELSE Alkalinity (dKH), Calcium, Magnesium — the parameters reef keepers obsess over. Plus Nitrate, Phosphate, pH, Salinity, Temperature, Ammonia, and Nitrite. Last values pre-fill automatically so a full test set takes under ten seconds, not one screen per parameter. TANK STABILITY SCORE ReefDrift calculates a Stable, Watch, or Danger score the instant you save a reading. The score weights every parameter against your target band and flags drift between sessions. A single alk swing from 8.4 to 7.1 dKH registers as Danger before you wonder why a frag is pale. Out-of-range chips light up on the dashboard immediately — no digging, no scrolling. DOSING CALCULATOR — WIRED TO YOUR TANK BRS 2-part, ESV B-Ionic, Red Sea Foundation, Aquaforest KH Coralline, and custom products. Enter tank volume and current reading; ReefDrift gives you the exact dose to hit your target. Works for alk, cal, mag, NO3, and PO4. The math uses your real tank volume, not a generic estimate. TREND CHARTS WITH TARGET-RANGE BANDS Every reading plotted on a line chart with your target band overlaid. See whether alkalinity is riding the top of the band, drifting toward the floor, or cycling after a large dose. Adjust the time window from 7 days to 12 months. MAINTENANCE LOG Record water changes, GFO swaps, ATO top-offs, carbon additions, and frag-tank moves. Cross-reference maintenance events against parameter charts to see what actually moved the needle. TEST REMINDERS Set a reminder per parameter or per task. ReefDrift sends a local notification on schedule — no server required. Never miss a Friday alk test again. HOME SCREEN WIDGET Your last three parameters and next task on your iPhone home screen or lock screen. See your tank status without opening the app. BUILT BY REEF HOBBYISTS We run SPS-dominant systems. We have watched a two-week alk drift destroy a $2,000 Acropora collection. We built ReefDrift because every existing option was either abandoned, clunky, cloud-first, or a bloated social network with a parameter logger bolted on. ReefDrift is ruthlessly focused: fast log, honest score, useful calculator. Nothing else. PRIVACY — YOUR DATA STAYS ON YOUR DEVICE No account. No cloud. No login. All readings are stored locally on your iPhone and never leave your device unless you export them as CSV. Nothing to hack, nothing to lose in a server outage.
