What's new in PoolFu: Safer water guidance PoolFu tells you whether your pool or spa is safe to use, needs caution, or should stay closed for now, with clear reasons and a recovery plan. Smarter dosing decisions PoolFu now handles tricky chemistry situations more carefully, including high pH with low alkalinity, persistent pH rise in saltwater pools, and chlorine targets at any stabilizer level. Better hot tub support Spa guidance now better reflects how hot tubs behave, including pH, foam, non-chlorine shock, and bromine spas. Bromine guidance now uses a 4 to 8 ppm acceptable range. Clearer recovery plans PoolFu now separates immediate, deferred, and optional steps, so you can see what matters first and what can wait. Indoor pool refinements Indoor pools no longer show seasonal winterization controls, and PoolFu now cleans up older indoor-pool settings automatically. Fixes and polish Pool and spa videos imported from your photo library now keep their original format, service media cleanup is more reliable, and chemistry explanations have been refined throughout.

What's new in PoolFu - New indoor/outdoor toggle for your pool, set when adding or editing. - Stabilizer (CYA) guidance now adapts to indoor pools, covered pools, sunny pools, saltwater systems, and spas. Clearer chemistry guidance - In stabilized outdoor pools, chlorine targets stay steady based on the proven chlorine-to-stabilizer relationship, with pH and temperature explained separately as water balance, comfort, and consumption context. - In indoor pools and freshly filled water with no CYA buffer, high pH guidance is sharper because pH has a stronger effect on active chlorine there. Language improvements - PoolFu now reads more naturally across all nine supported languages. User experience improvements - Notifications now prompt at the right moment instead of staying quietly off. - The "Rate PoolFu" prompt only appears after you actually save a new water test.
