Tolfi · pronounced "TOLL-fee"

It doesn't motivate.
It decides.

Tolfi writes today's session, meals, and recovery targets from what your body actually did — live on your Apple Watch. Now invite-only.

Real screens · live on iPhone + Apple Watch Tolfi on iPhone — readiness rings, today's planned workout, and Start Workout Tolfi on Apple Watch Ultra — post-set confirm card with rep and weight steppers

Today's plan on the phone · set logging on the wrist — captured from the shipping app.

Three pillars · one brain

No competitor closes the loop. We do.

Most apps pick one. Tolfi reads all three — and acts on them. The triangle of program / macros / wearable, collapsed into one system that decides instead of describes.

  1. Pillar 1

    Training

    A rules engine + classical ML + on-device and cloud LLMs working as one system, running native on Apple Watch — rep detection, plate math, and a post-set confirm on your wrist. Methodology bundles you can read, not a black box. Calibration in session one; the block breaks when you plateau. Same engine on server and in your pocket.

    Push Past · RP-style · custom — same engine.

  2. Pillar 2

    Diet

    Photograph a meal or your fridge — Tolfi logs it, builds the plan from what you have, and re-solves today's macros around what your body did and what you burned this session. Not a food log dressed up as coaching.

    Photo logging · pantry-aware · adaptive macros.

  3. Pillar 3

    Biomarkers

    HRV, sleep, the body scanner, and a 4-week check-in close the loop. Recovery state adjusts today's plan — it doesn't just sit on a dashboard you ignore.

    Check-in re-anchors weights and macros every cycle.

Shipping now

Built, not roadmapped.

Everything below is live in the app today — not a promise. This is what the engine drives.

  1. 01

    Watch-native workouts

    Start, run, and finish a session from your wrist. Rep detection, inverse plate math, and a post-set confirm card — the phone's a backstop.

  2. 02

    AI coach — chat & voice

    Talk to Tolfi by text or full-duplex voice. It reads your actual training and diet, and never plans without the engine behind it.

  3. 03

    Photo food logging

    Photograph the plate. Tolfi identifies it, logs the macros, and folds it into today's plan.

  4. 04

    Adaptive meal plan

    A daily plan that re-solves around what you ate and what you burned this session — never punitive.

  5. 05

    Body scanner

    Composition, ratios, and a priority-advance trigger that feeds the recovery loop.

  6. 06

    Gym intelligence

    Tolfi learns your gym's machines and bars, so plate math and weights match the room you're actually in.

  7. 07

    Partner training

    Train with a partner: shared schedule, synced sessions, weights priced to each lifter.

  8. 08

    Exercise demo videos

    Every movement in your plan ships with a demo so form is never a guess.

Human coaches can drive Tolfi for their own clients through a separate web console.

What we stand against

If it isn't reasoned, it isn't worth following.

  • Generic plans dressed as personalization
    A real algorithm decides the next set, the next session, the next block — not a static template with your name on it.
  • A chatbot that makes up your plan
    Tolfi has an AI coach you can talk to — chat or voice — but the AI never plans alone: a deterministic engine holds the floor. The LLM explains and adjusts; the engine writes the plan.
  • Streak shame and gamification trash
    Adherence is hard. We don't punish slips — we adapt to them. The block shifts, the macros shift, the next session changes.
  • Hype without proof
    Methodology bundles are readable. The engine is the same on server and on device. Calibration learns your numbers in session one.
