Read full description

Float Seattle is the member app for Float Seattle — five float therapy studios across the Seattle area. See your practice. Your visits, your streak, the mix of what you book, and how many membership credits you have left this cycle. It fills in automatically from your studio account — there is nothing to enter. Book without hunting for a tab. Pick a studio, a service and a time. Your next float sits at the top of the app with the address and directions, and how long you have left to change it. Everything you need before you arrive. Real opening hours for all five studios, what each one offers, what it costs, and how long it takes. Wednesday closures included, so you never turn up to a locked door. A practice between sessions. A guided breathing timer and a private float journal. Both work offline. Your journal never leaves your phone. No account needed to look around. Studios, pricing, the breathing timer and the journal all work without signing in. Connect your Float Seattle account when you want your own visits to appear. Greenlake · Greenwood · Bellevue · South Lake Union · Renton Landing
