01

The challenge

Coaching apps are either simple trackers with no human, or spreadsheets a coach maintains by hand. Neither scales real, personalised coaching.

02

What we built

Dextra pairs certified coaches with app-based tracking: workouts with instant PR alerts, nutrition, weekly check-ins, and an AI performance report that briefs the coach on each client.

We handle the product end to end — the iOS and Android apps, the coach dashboard, the AI reports, and a payment stack built for the Tunisian market. It's our flagship product and our proof that we ship.

03 · Inside the product

What the product does.

Dextra pairs real certified coaches with app-based tracking — workouts, nutrition, and weekly check-ins in one place. Not just a tracker; a transformation system. It's Singleton's flagship product, live on the web, iOS and Android, in English, French, and Arabic.

  1. 01

    Workout tracking

    Real-time session logging with instant personal-record alerts — sets, reps, load, and progression.

  2. 02

    Weekly check-ins

    Coach-sent questions with photos, measurements, and notes, reviewed every week.

  3. 03

    Metrics dashboard

    Weight, body fat, waist, load, sleep, calories, and streaks — the full picture in one view.

  4. 04

    Personalized programming

    Certified coaches build custom programs for each client, not templates.

  5. 05

    AI performance reports

    Coaches get a weekly AI briefing on each client's PRs, volume, and consistency.

  6. 06

    Payments built in

    Flouci, D17, Click to Pay, and bank transfer — built for how Tunisia actually pays.
