About this app

Take control of your strength training with a smarter, cleaner approach to the gym.

TUT (Time Under Tension) is built for lifters and athletes who want to focus on what actually stimulates muscle growth: quality movement, mechanical work, and time under tension—without annoying subscription paywalls, clunky menus, or invasive data tracking.

Whether you train in a commercial fitness club, a CrossFit box, or your own garage gym, TUT gives you total freedom to log your workouts your way.

========================

WHY TIME UNDER TENSION?

========================

Rep counts only tell part of the story. TUT helps you monitor the actual mechanical workload and duration your muscles experience during every set. Maximize hypertrophy, track progressive overload with precision, and make every second at the gym deliver results.

Store update history

Each store’s release notes, as the developer wrote them. They are the developer’s words, not ours.

App Store

Version 1.2 · 2026-10-16
Introduced customizable biological physique inputs with integrated muscle recovery heatmaps in a dedicated "Readiness" tab. A user can now enter their physical measurements to keep track of this over time. Introduced Grecian model target proportions.

It can be found in the Question Mark icon on the Equipment Gallery view. Updated coaching insights that can now be cleared. These are the built in coach rules: RULE 1: Progressive Overload (10 straight sessions at exact same load) RULE 2: High TUT…

Method and limits

What this report can and cannot show

What a missing label means

Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.

Limits of this report

  • A package scan is static. It identifies code and text in one Android build. It does not measure a live ad session, test a deletion request, or count the steps needed to cancel.
  • Reviews keep their sample. A review-only charge shows distinct reviewers, the share and the sample size, and is published only once it clears that label’s published threshold. Calibration labels are machine-drafted and not yet confirmed by a person.
  • Not assessed is a state. It is never a zero and never a pass.
  • A missing label is not a clean bill of health. It means the evidence did not support one, not that the app is problem-free.
Not yet human-reviewed. A human review gives an app hands-on, recorded measurements. None has been run for this app. Hands-on inspections are not yet open.
