One App. Coach and Client, In Sync.
As a fitness coach app, Tandem replaces scattered spreadsheets, voice notes and WhatsApp messages with a professional dashboard where everything lives: nutrition logs, workout plans, training schedules, health data and client progress — visible in real time.
For Coaches: Full Visibility Over Every Client
The Tandem coach dashboard shows you every client at a glance. See who is logging their meals, who skipped a workout, and who is consistently hitting their water intake targets. Dive into any individual client profile to review their full nutrition diary — including food photos, voice entries and manual logs.
Set personalised calorie and macronutrient targets (KBJU) for each client. Assign workouts with animated exercise demonstrations so technique is never lost in translation. Build and manage your weekly training schedule in the built-in calendar. Monitor live heart rate data and step counts from clients wearing Apple Watch.
For Clients: Everything They Need to Succeed
Tandem makes the client experience effortless. Clients log meals in seconds — a photo, a voice note, or a manual text entry all calculate nutrition automatically. They see their personalised workout schedule, follow each exercise with animated technique guides, and track their daily water intake with a simple tap.
Apple Watch integration pulls health data directly into the app: steps, heart rate, calories burned and activity rings. Clients see their progress in one clear dashboard — and so do you.
