ReefNote vs Recif

ReefNote keeps your aquarium on track: log every water parameter, flag anything out of range, and keep dosing and maintenance on schedule. Testing is fast. Pick a parameter, tap the value on a big pad with the right unit (dKH, ppm, SG), and save. Each parameter remembers its last value, so a routine round of tests takes seconds. WHAT YOU GET - Parameter log with target ranges: reef and freshwater presets you can edit per tank, with out-of-range flags the moment you save - Trend charts: every parameter over 30 days, 90 days, or a year, with your target band drawn behind the line and each point coloured by its flag - Dosing and water changes: repeat schedules with clear overdue and due-today states, one tap to mark done - Livestock registry: fish, coral, and inverts with photos, added dates, and notes - Maintenance reminders: a per-task reminder so nothing slips - Tank journal: one timeline that mixes your tests, doses, and events - Tank report: a shareable PDF of parameters versus targets, livestock, and schedule, plus a CSV of every reading (Pro) REEF OR FRESHWATER Set the tank type and ReefNote starts with common target bands for each parameter, then lets you tune every band to the numbers you keep.
