ClassPass sells credits you spend on classes. Corvi is a free app for the classes you already take: check in, keep your streak, rate instructors, and see where friends train. Corvi does not book classes, sell credits, or take payments. You book with ClassPass or your studio, then check in on Corvi.
A free, ad-supported social app for class-based fitness. Find studios and classes near you, check in when you attend (verified by location), keep streaks and weekly goals, hit milestones, rate instructors after classes you took, and follow friends and instructors. Web app available now; iPhone and Android apps are coming soon.
A monthly subscription that gives you credits to book classes, gym time, and spa appointments at partner businesses. US plans run from $19 for 8 credits to $249 for 125 credits a month as of October 2026, and each class costs a variable number of credits depending on time, demand, and equipment.

Use ClassPass, your studio's app, or a membership. Corvi works with all of them.
Open Corvi when you arrive. Location verification makes the class count toward your streak and weekly goal.
See where your crew trains, rate the instructor, and celebrate milestones together.
Our guides cover the booking side honestly, with dated prices and sources:
Whichever way you book, keeping track is free. See everything Corvi does
No. Corvi does not book classes, sell credits, or take payments. You book with your studio, through ClassPass, or with any booking app you already use. Then you check in on Corvi when you arrive, which counts the class toward your streaks, weekly goals, and milestones, and lets your friends see where you trained.
Partly. Corvi covers the discovery and motivation side: finding studios and classes, tracking attendance, rating instructors, and training with friends. It does not replace the booking side. If you are leaving ClassPass, book with studios directly and use Corvi to keep track. If you are staying, use both together.
Yes. Book a class on ClassPass as usual, then check in on Corvi at the studio. Your check-in is verified by location, so it counts toward your streak and weekly goal. Corvi works the same way for studio memberships, class packs, and drop-ins, so your history stays in one place if you switch how you pay.
Corvi is free and supported by ads. ClassPass costs $19 to $249 a month in the US as of October 2026, plus tax, depending on how many credits you buy. You still pay your studio or ClassPass for classes; Corvi adds no cost on top.
ClassPass only records classes booked through ClassPass, and that history stays there if you cancel. Corvi tracks every class you check in to, however you booked it, and adds streaks, weekly goals, instructor ratings, and a feed of where friends train.
Track every class, keep your streak alive, and see where your friends are working out. Corvi is free.
iPhone and Android apps coming soon.
