Naamly Client

Features
Read full description

Naamly Client is the member app for fitness studios, gyms, and training facilities that run on Naamly. Sign in with the phone number your studio has on file and everything you need is in one place — your schedule, your visit history, your documents, and your payment methods. BOOK IN SECONDS Browse your studio's live schedule, filter by session type, and see exactly how many credits you have left before you commit. If a session is full, join the waitlist and get notified the moment a spot opens. Add any booking to your device calendar, Google Calendar, or Outlook with one tap. KEEP TRACK OF YOUR TRAINING Your dashboard shows what actually matters: total visits, sessions this week, your 4- and 8-week counts, and a consistency bar that makes streaks easy to see at a glance. Full attendance history is always a tap away. MANAGE THE WHOLE FAMILY Switch between the contacts linked to your account and view a combined family schedule, so you can see everyone's sessions without logging in and out. STAY IN THE LOOP Announcements and messages from your studio arrive as push notifications and stay collected in one place, so you never miss a schedule change or a closure. DOCUMENTS AND MEDIA View and upload waivers, agreements, and forms. Watch training videos, listen to audio, and open PDFs without leaving the app. PAYMENTS AND MEMBERSHIP Add or update cards and bank accounts securely through Stripe — including ACH, BECS, and ACSS debit. Buy session passes, review your subscriptions, and set a default payment method. YOUR PROFILE Update your details, address, and profile photo with a built-in cropper, and change your password whenever you need to. Naamly Client requires an active account with a studio that uses Naamly. If you are not sure whether your studio is on Naamly, ask at your front desk. This is the beta release. Some features are still being refined, and we would genuinely like to hear what is not working for you — reach us at sriram@naamly.com.
