Read full description

The HOTWORX application is indented for members of our HOTWORX Studio facilities. The purpose of this application is to encourage users to track their total amount of calories burned during a HOTWORX workout session, and to track their "1-hour after-burn." A HOTWORX workout is 40 minutes, and the after-burn is 1 hour. The total session time will capture the calories burned for a total of 100 minutes. This app integrates with the Health app.

About

Grounded Studios

Read full description

Grounded Studios is a Pilates pop-up in Atlanta. No permanent studio, no membership, no chain-gym energy. Every class lands somewhere different: a roastery, a garden, a farm. This app is how you keep up with where we're going next. SEE WHAT'S COMING Every upcoming class in one place, with the date, time, location, and what's included. The rooms are small and they sell out, so you can see how many spots are left before you book. If one's already full, join the waitlist and we'll text you when something opens up. COLLECT YOUR PASSPORT Show up to a class and you earn a stamp. Every class has its own, and they collect in a passport you flip through like the real thing. Add a photo to any stamp to remember the day, and save a page whenever you want to share it. FIND EVERY POP-UP A map of everywhere we've been around Atlanta, plus a view of just the spots you've made it to. Directions to the next one are one tap away. NEVER MISS A DROP Turn on notifications and we'll tell you when a new class is announced, when a waitlist spot opens up, and when you've earned a stamp. NO PASSWORDS Sign in with your phone number and that's it. Your bookings show up on their own, and any class can go straight to your calendar. Where we've popped up so far: The Holler, Eden Smoothies, Thrive Canton, Nix Generation, and a private farm outside the city. Come move with us, then stick around. groundedstudios.fit @groundedstudiosatl
