Adaptive training log

Keep the plan.
Adapt the day.

You already train. What you don’t have is a plan that survives a bad night’s sleep, a 45-minute gap and a busy squat rack. Didit adjusts the session you’re about to do — and shows you exactly why.

THE ONE RULE

A fact and a suggestion should never look the same.

Most training apps blur the two, so you stop trusting either. In Didit your own history is quiet and neutral. Anything the app proposes sits on green, carries its evidence, and says how sure it is.

Amber never means the app is unsure of itself — it means you should look twice.

THIRTY SECONDS BEFORE YOU TRAIN

Three taps, then it’s your call.

Say how the day is going
Energy, time you actually have, which gym, anything that hurts. Four taps, no typing needed.

Read the evidence, not the verdict
Didit leads with what it is working from — each fact with its source — then the prescription and how sure it is.

Nothing is required, ever
Skip the check-in and you get the plan as written. Skip the whole setup and Didit works as a fast, plain log until you’ve built enough history for it to have an opinion. It won’t invent loads it hasn’t seen you lift.
○No check-in? You get the plan as written.
○No wearable? Suggestions lean on your logged sets.
○No history yet? It logs, and stays quiet.
CALENDAR

A 45-minute session is never 45 minutes of your day.

Connect your calendar and Didit places sessions in the gaps that actually exist — then sizes each one door to door, counting the travel, the warm-up and the shower. That’s why it never offers you a 60-minute session in a 60-minute gap.

Plans around your week
Sessions land in real gaps, not in the middle of a meeting.
Counts the whole trip
Travel, warm-up, cool-down, shower and food — configurable once.
Shrinks the session, not the point
Short window trims accessories and protects the main lift.
Moves when your week moves
A late meeting reschedules the session instead of killing it.

Reads iCloud, Google and Outlook calendars. Buffers are set once in your profile and can differ per gym.

Your calendar shows a 92-minute gap. Only 45 of it can be spent under the bar — so Didit trimmed the two lowest-priority accessories, not the bench work.

Runs, rides and classes arrive as endurance load, so Didit knows what your legs already did.

APPLE HEALTH

One integration instead of one per device.

Whatever already writes to Health — your watch, a chest strap, a ring — Didit reads from there. Sleep, HRV and resting heart rate become the recovery signal behind each suggestion; your cardio arrives as endurance load; finished strength sessions get written back so Health stays complete.

Each direction is a separate permission, granted in Apple’s own sheet and revocable in the Health app. Turn recovery off and Didit stops citing it — the adaptations keep working from your logged sets.
