Workout log

A workout log that never slows you down

At the gym your fingers are sweaty, the Wi-Fi drops and rest is short. SimuFit’s workout screen is made for exactly that: one hand, two taps, no waiting.

At the gym

Everything you need, nothing you don’t

Two taps per set

Weight is prefilled from last time. Tap reps and ✓ – or just ✓ to fill last time’s reps.

Rest ring

The timer appears next to the exercise name. +30 s, tap to skip, a buzz and a beep at zero.

Progression hint

When every set reaches the top of the rep range, SimuFit suggests your next weight.

Swap an exercise

Machine taken? Pick a similar, no-equipment, easier or harder option – today only or for good.

Video at hand

A short technique video opens right in the exercise card when you want to check your form.

Offline

Everything works in a basement gym. Logs are saved on your device and sync later.

Today

Open the app – today’s workout is already there

The Today screen shows which workout is next: the day you did longest ago, or the day on your schedule. You see the number of exercises, sets and estimated time, and one big button starts the workout.

Questions and answers

Does the workout log work without internet?

Yes. The whole workout screen works offline, and logs are saved on your device first. They sync to your account when you are back online.

What happens if my phone locks or the app closes mid-workout?

Your in-progress workout is kept and you continue where you left off. The screen stays awake during a workout in supported browsers.

Can I log RIR or notes?

Yes. Per-set RIR sits behind a “more” toggle so the default row stays simple, and every exercise can have a note.

Can I use my own program?

Build one from the exercise library or paste your old program as text. You can also start an empty workout and add exercises freely.

Your first workout in under three minutes.

Answer a few questions, get your program, and the workout screen is ready for the gym. Runs in your browser: no app store, no install.
