CrimpDex turns a Tindeq Progressor into a proper testing tool. It measures, records and compares. It does not coach, nag, or ask you to sign up for anything.
Free for seven days. One payment after that, no subscription.
Everything here exists to answer one question: is this getting better or not? The numbers are the interface.
Connect the Progressor and read the load as it happens, at full sample rate. Tare from any screen. Every value is set in tabular monospace, so the digits hold their place instead of jittering while you pull.
Three maximal attempts with the rest countdowns between them. CrimpDex tracks the live peak through each one and keeps the best. That is your ceiling.
The twenty-four rep protocol at seven seconds on, three off. Your critical force is calculated from the mean of the last six reps, once the curve has flattened.
Strength to bodyweight. Left and right asymmetry, flagged past 10%. Critical force as a share of peak, with the range it usually sits in.
Max pulls, repeaters, density pulls and critical force intervals, each with a target load computed from your own baseline, an interval timer, and a live bar showing where you are against that target.
Hand, edge depth, time under tension, rest, reps, sets and rest between sets. Load as a share of your baseline, ramping across sets, or a fixed weight when you want a specific number. Alternating hands is a setting, not a workaround.
Right hand is always lime. Left hand is always cyan. On every screen, every chart, every reading, so you never have to check a legend mid-set.
Bluetooth, no account, no setup wizard. CrimpDex finds it and starts reading.
Peak force takes about ten minutes with the rests. Critical force takes four. Do each hand. No Progressor to hand yet? Type the numbers in from any test.
Every protocol now knows what your 65% actually weighs. The timer runs the intervals and the bar shows whether you are on target, rep by rep.
Peak force moves slowly. Critical force moves faster. The chart shows both without flattering either.
CrimpDex declares no internet permission at all. Android will not let it open a network connection under any circumstance, so there is no server to trust and no account to delete. Readings live in a private database on your device.
No email, no password, no profile. Install it and start measuring.
No advertising SDK, no crash reporter, no third party collecting anything.
Android Auto Backup may copy the database into your own Google Drive, encrypted with your device passcode. That copy is yours, not ours. Full policy.
No subscription, no renewal, no tiers, and no feature held back for a higher plan. The trial is the whole app.
CrimpDex is in closed testing on Google Play. Get in touch and I will add you to the tester list.
For live measurement, yes. The Progressor is a Bluetooth load cell made by Tindeq, and CrimpDex reads from it directly. Without one you can still enter values by hand from any test and use every protocol, chart and calculation. CrimpDex is not a Tindeq product and is not affiliated with Tindeq.
Entirely. The app has no internet permission, so it could not phone home even if it wanted to. Everything runs on the device, unlock codes included.
Peak force is the hardest you can pull once. Critical force is the load you can keep coming back to without fading, measured over twenty-four pulls. It usually lands between 35% and 45% of peak. Peak tells you about one hard move; critical force tells you whether you will still be holding on near the top of the route.
Yes. A custom protocol can be left hand only, right hand only, or alternating, where a full set on one hand is followed by the same on the other before the rest between sets.
Yes. A custom protocol's load can be a share of your peak force, a share of your critical force, or a fixed weight in whichever unit you have chosen in Settings. Percentages keep up as you get stronger; a fixed weight is there for rehab loads and anything a physiotherapist has written down.
Android 8.0 and later, on a phone with Bluetooth Low Energy. Built and tested against Android 16.
The purchase goes through Google Play, so Play's own refund process applies. Request one from your Google Play order history, or email me and I will help sort it out.
Bugs, a reading that looks wrong, a protocol you cannot express in the builder, or a request to join the tester list. It all goes to the same address.
Say which phone you are on and, if a number looked wrong, what you expected instead.
Nothing, and the app cannot open a network connection to change that. Read the policy.
There is no account to close. Removing the app removes the database with it. To clear it without uninstalling, use Android's Clear storage for CrimpDex.
