Store description excerpt
The tank you look at every day is the one whose small changes you stop noticing. SUIKEI keeps your tank's photos, care logs and water readings together, so you can look back on how it grew. One tank is free for as long as you like — photos, care and readings, all of it. And for 45 days from the day you add your first tank, every Premium feature is open too. No ads, anywhere. ■ What you can do with SUIKEI ・Log a water change or a feeding in two taps Quick enough to do standing at the tank. "When was the last water change?" is easy to answer later. ・Look back on your tank in photos Photos are filed by month, so plant growth, your fish, and layout changes read as a record of the tank growing. ・Fixed-point photos, the same angle every time The previous photo is ghosted over the camera, so you shoot from the same spot at the same angle. Put past and present side by side and the small changes are obvious. ・Water readings in the units you already use Enter them exactly as your test kit shows them. NO₃ and NO₃-N, °dH and ppm, specific gravity and salinity convert automatically, hydrometer calibration temperature included. ・No ads, even on the free plan Not while you log, not while you look back. Time with your tank should be quiet. ■ Free, for as long as you like ・One tank ・Recording and editing photos, care logs and water readings, with no limit on how many ・Fixed-point photos ・Your oldest photo and your newest, side by side ・Time-lapse of up to 10 frames ・Export and delete your data For 45 days from the day you add your first tank, the Premium features are open as well. After those 45 days, one tank keeps going, free. ■ SUIKEI Premium For keeping several tanks, or following the changes more closely. ・As many tanks as you like ・Compare any two days you choose ・Time-lapse across every photo ・Several fixed points per tank — front, side, top ・Cloud backup Monthly: JPY 480 / month Yearly: JPY 4,800 / year (JPY 400 per month) ■ About purchases ・Payment is charged to your Apple ID. ・It renews at the same plan and price unless cancelled at least 24 hours before the period ends. ・The renewal is charged within 24 hours before the current period ends. ・Cancel from the subscription settings on your device. Cancellation is not possible from within the app. ・If you buy a paid plan during the 45-day free period, the unused part of that period ends at that point.
