A private diary and session planner for independent personal trainers: plan your day, prep each client, run and record every session.

Your whole training day in one place
Trainer's Day is built for self-employed personal trainers who juggle a paper diary, a notes app and a head full of client details. It puts your bookings, your clients and your session notes together, so you can see the day ahead, walk into every session prepared and record what happened before the next client arrives.
Plan the day. Today and Week views show every booking at a glance. Repeat a booking weekly, mark cancellations and no-shows, and let the app warn you about double bookings and clock changes.
Know every client. Each client has a record with contact details, preferences, private notes and their full session history. A pre-start questionnaire captures goals, experience, availability, equipment and any movements to take care with. Fill it in yourself, hand your phone to the client, or send the questions by text.
Prep, run and record. Before a session, the prep screen shows what you did last time, talking points and an equipment checklist. During the session, log sets, reps, load, effort and notes, pre-filled from the programme or from last time.
Free, with an optional Pro upgrade
The diary, clients, questionnaires, prep, session records, reminders and exports are free, with no limit on clients or bookings. Trainer's Day Pro adds a programme builder with a 75-exercise library, reusable templates, suggestions informed by each client's questionnaire, automatic session briefs built from your own records, and progress views. Your first programme is free, and programmes stay usable if you ever stop Pro.
Trainer's Day helps you organise your own professional judgement. It doesn't give medical advice or decide whether an exercise is safe.

Frequently asked questions
Is Trainer's Day free?
Yes. The diary, clients, questionnaires, session prep, records, reminders and exports are free with no limit on clients or bookings. Trainer's Day Pro is an optional subscription that adds the programme builder, templates, session briefs and progress views.
What happens to my programmes if I cancel Pro?
They stay viewable, editable and exportable. Your first programme is free and can't be taken away.
Do my clients need the app or an account?
No. Clients don't have accounts. They can fill in the questionnaire on your phone or reply to questions you send by text. If a client wants a copy of their details or wants them deleted, you can export or delete them in the app.
Does it work offline, and on more than one phone?
Yes. A copy is kept on your phone so it works without signal, and it syncs through your Google account when you're back online.
Does it give medical or safety advice?
No. Suggestions are advisory and based on what you and your client have recorded. Trainer's Day never says whether an exercise is safe or unsafe; that's your professional call.
