Our biggest update ever.
Photo albums: send up to 30 photos in one message. They display as a clean album grid, tap any photo to view full screen and swipe through.
Live streaming leveled up: full screen video with chat overlaid on top, see how many people are watching, and admins can see who is in the stream. Streams are protected against screen recording with watermarks throughout.
Reef Cam: a built in camera filter for blue reef lighting. Shoot your corals through an orange or yellow filter with adjustable intensity, no more holding a physical filter over your phone. Members can save filtered photos to their camera roll.
My Tank 2.0: log your entire test session in one screen, see trend charts with your ideal ranges, set test reminders, and see mini trend lines right on your tank page.
Plus smoother navigation, admin improvements, and reliability fixes throughout.
