How to correctly wear your FITTR HART Ring For best performance and accurate readings, we recommend wearing your HART Ring on the index finger of your non-dominant hand. Middle and ring fingers work too, if that’s what you prefer. Just make sure that the ring fits securely and comfortably around the base of your finger - not too loose, not too tight. Note: the ring’s sensor should face the palm side of your finger and not the top. How to use the FITTR ONE app After activating the ring, please pair with the FITTR ONE app to start using. Not a medical device This ring is not a medical device and should not be used as a substitute for professional medical judgement. It is not designed or intended for use in the diagnosis of disease or other conditions, or in the cure, mitigation, treatment, or prevention of any condition or disease. Please consult your healthcare professional prior to making any decisions related to your health.

Strail is built from the ground up for Studios with large gym chains running multiple sessions and stretched to fit for personal trainer and fitness coaches as an afterthought. Manage clients, sessions, trainer payouts, fee collections, and studio activity from one mobile app. CLIENT MANAGEMENT: Keep every client's details in one place. Add profiles with photos or pick from 24 illustrated avatars. Import selected contacts in a single tap after granting permission. Track membership status, see who is active, paused, or archived, and keep private notes (goals, injuries, preferences) on each profile. PAYMENT TRACKING: Track monthly fees with clear status — pending, due today, overdue, paid. Mark a fee paid in seconds. When you change a session's fee, every active client's fee and unpaid invoice updates automatically. WHATSAPP REMINDERS AND INVOICES: Send fee reminders via WhatsApp in one tap. After payment, send a clean WhatsApp invoice receipt with session name, amount paid, and billing month — written confirmation for your clients. Both messages are fully customisable from Settings with placeholders for client name, studio, amount, due date, session, and billing month. WhatsApp open rates far exceed email or SMS, so your clients actually see the message. TRAINER MANAGEMENT: Manage trainers from the People tab. Track assigned sessions, mark absence or inactive days, and monitor monthly payouts. Trainer payout tracking is first-class. Mark payouts paid or unpaid with one tap, edit payouts on the fly, and view a full payout history without a spreadsheet. A built-in absence calendar gives you a month-at-a-glance view of every trainer's presence. SESSION SCHEDULING: Create individual sessions, group classes, fitness programs and coaching batches. Set days, timing, duration, location, fee, capacity, and assign trainer. Capacity badges and slot counters help you avoid overbooking. HOME DASHBOARD: A daily overview of your studio: pending fees, upcoming sessions and reminders — everything for daily operations. REVENUE DASHBOARD: A complete view of client fees, trainer payouts, monthly totals, and recent activity. Revenue breakdown for sessions. LIVE ACTIVITIES: Real-time studio and session updates on your Lock Screen and Dynamic Island without opening the app. PRIVATE ICLOUD BACKUP: Strail stores data locally by default.
