Concepts
The mental model behind Yarmill — instances, groups, plan vs. reality, and how the modules fit together.
The mental model behind Yarmill — read it once, and everything else builds on it.
Your instance
Your team has its own configured Yarmill environment — an instance — at its own
team URL (your-team.yarmill.com).
You sign in with your email and password. The mobile app also asks for the team URL, which you'll find in your confirmation email.
Plan and Reality
Yarmill is organized around two questions: what you planned, and what actually happened.
Coaches build the Plan; athletes (and coaches) record Reality — the training diary. Keeping them separate is what lets Yarmill show the gap between intention and execution, and turn it into Analytics.
There are actually three versions of training data:
- Annual plan — the season-start intention, entered by month or mesocycle.
- Plan — the operational plan, built week to week and adjusted as life intervenes.
- Reality — what the athlete actually did.
The Season review shows all three side by side.
Left side, right side
A day's entry — in Plan and in Reality — has two halves:
- Left (text) side — free-form description in your own words: the workout, the methodology, notes. Split into training phases (for example morning and afternoon; your instance configures these).
- Right (data) side — the numbers: minutes, kilometers, sessions, intensity zones. Some rows are calculated automatically and shown locked.
Reality can carry extra fields the coach doesn't plan but the athlete should record — RPE, notes, attachments — tucked under the day's ⋯ menu.
Copy plan and Import plan
Two actions move data between the worlds:
- Copy plan (coach) — planning on the whole group is your private sandbox. Athletes see nothing until you publish with Copy plan. Editing a single athlete's plan is visible to them immediately.
- Import plan (athlete) — copies the planned day into Reality with one click, ready to edit into what really happened. Some teams disable it so athletes write in their own words.
Auto-save
There is no Save button. Changes save as you type.
Significant changes (states, dates, values) are recorded in each module's Activity log with who did what, when.
Groups, roles, and what you can see
A group is the coach's organizing unit of athletes — athletes don't see groups. There are three account types:
- Athlete — sees and edits only their own data; views the plan but can't edit it.
- Coach — works with assigned groups: plans, publishes, reviews, and manages athletes' records. Staff like physiotherapists typically use coach-type accounts, and self-coached athletes get one so they can write their own plan.
- Administrator — manages people, groups, and permissions in Settings.
If a module or athlete isn't visible to you, it's usually permissions or configuration — ask your administrator.
Devices and HR zones
Athletes connect sports watches and other devices in Settings → Applications & devices. Recorded activities and sleep data then appear automatically under the day in Reality.
Watch data complements the diary — it doesn't replace writing the left and right sides. Heart-rate zones are set in Yarmill, per activity and with validity periods, so your time-in-zone stays consistent even when you change watch brands. See Devices & integrations.
Where you work
- Web app — the full feature set; where coaches and administrators live.
- Mobile apps (iOS/Android) — athlete-focused: today's plan, logging, watch data.
- PWA — "add to home screen" from the web app; the recommended phone experience for coaches, and works for athletes too.
Module pages note Where a task is done, so you always know which to reach for.
