Help & Guide

Trainingszettel lets you build workout plans and log every set with your thumb — completely private and local in your browser. No account, no cloud, no cookies.

Quick start

1. Create a profile

On first visit you land on the profile picker. Create a profile with a name (plus optional emoji and color). You can have multiple profiles on the same device for different people or training styles.

2. Land on „Today“

After picking a profile you arrive at the „Heute“ (Today) launch screen. From here you can start a free workout or pick one of your templates instantly.

3. Log your sets

In the workout screen just tap the big buttons. Adjust weight/reps, mark sets done — that's it. The rest timer starts automatically if you have it enabled.

The „Today“ screen

Your daily hub. You see:

• Your own templates (sorted by „due“)
• Built-in starter templates (Push, Pull, Legs, etc.)
• The „Start free workout“ button
• A resume prompt if you have an unfinished draft

Tip: If you haven't exported in a while you'll see a backup reminder here. Your data only lives in this browser!

Logging sets

The core of the app. The workout screen is optimized for the gym:

• Large, thumb-friendly targets that work even with sweaty hands or gloves.
• „Last time“ values are pre-filled automatically (ghost values).
• Warm-up sets are supported (they don't count toward PRs or volume).
• Rest timer with configurable default and auto-start option.
• When you're done, tap „Finish workout“ — everything is saved locally and you get a summary.

Working with templates

• Templates are reusable workout plans.
• Create them from the „Vorlagen“ (Templates) screen or directly after finishing a workout („Save as template“).
• You can reorder, add or remove exercises inside a template.
• When you start a template it automatically seeds the best last-known weights/reps for you.

Weekly plan & rotation

Under “Plan” you decide which days you train what — then “Today” shows you exactly what’s up.

• Weekdays: assign one or more templates to each day (e.g. Mon + Thu legs, Tue + Fri arms). Days without a template are rest days.
• Rotation: your workouts in a fixed order, independent of the weekday — after each finished workout the next one is up.
• On “Today” you start the planned workout with one tap. Finished workouts are marked as done.
• Your plan references your templates — edit a template and the plan picks up the change automatically.

History & Progress

Under „Verlauf“ (History) you see all finished workouts in chronological order. Tap any entry for full details.

The „Fortschritt“ (Dashboard) tab shows:

• Personal records (PRs) per exercise
• Volume trends and charts
• Quick overview of recent sessions

Your data – Export & Backup

Everything (profiles, plans, logged workouts) lives only locally in your browser (IndexedDB + localStorage).

Export regularly! Go to Settings → „Export data (JSON)“. The file can be imported again later (even on another device or browser).

You can also completely delete a profile from the Settings screen.

Gym tips

• The app works offline once it has been loaded once (service worker + cache).
• Big touch targets — great on a phone in your hand or lying on the bench.
• Rest timer + optional notifications help with timing between sets.
• If you train on multiple devices: export/import regularly or just bring the same phone.
• Always export before clearing browser data or switching devices.
