Force Board Portable
Every rep, measured.
Force Board is a pocket-size force gauge for finger and strength training. Clip it between a hold or handle and an anchor, then pull. The free app shows your force live and saves every rep, so you can see whether you're actually getting stronger.

How it works
Clip it in. Pull. See every rep.
-
01
Clip it in
Run the strap from your hold or handle to an anchor and clip Force Board in between. A hangboard, a block, a pull-up bar or a PitchSix platform all work.
-
02
Pull
A rep starts when you pull and ends when you let go. Routines stay timed, but Force Board waits for you, so you never have to tap your phone between reps.
-
03
See every rep
Your force shows live, an audio cue tells you when you hit your target, and each rep is saved with its peak, average, rate of force development and time.
Inside the app
This is what training with Force Board looks like.
Real screen recordings from the Force Board app. What you see here is what you get on your phone.
-
01
Live force on every pull
Set a target and pull. The rep starts when you pull and stops when you let go, and you see your force live with your percent of target. RFD, average, max and current update on every rep.
-
02
Repeaters on a 20 mm edge
Load a routine and the app runs it: pull and rest timers, left and right hands, and the max of every rep logged as you go. You can see exactly where you start to fade.
-
03
Every set and rep, on the clock
Pull when the timer turns green and rest when it turns red. The app steps through every rep and set on its own and logs your max as you go, so your phone can stay on the floor.
-
04
Test your baseline
Run a peak force or critical force test on a 20 mm edge. The result lands in your feed, so you can retest in a few weeks and see exactly what changed.
-
05
Build any routine you can think of
Pick your board and the exact holds, one hand or both. Set reps, sets, hang and rest times and a target load for each hold. Save it and it runs the same way every session, and you can save as many routines as you want.
-
06
Track every workout
Every session lands in your feed with your pulls, time under load and a bar for every rep. Tap to switch between max, average and time. Free, with no limit.
-
07
See your progress toward your goals
Every session on a routine lands on one chart, so you can see how your strength changes week to week. Set a goal and watch your numbers climb toward it, hold by hold, in max, average or rate of force development.
Optional upgrade, $29.99 a year or $4.99 a month
Built for fingers
Train your fingers the way you climb.
Clip Force Board between any hold and an anchor and every grip becomes a number you can track: half crimp, open hand or pinch, one arm or two.
-
Peak force
Max hangs
Find your peak on a 20 mm edge, then train close to it. Every rep logs peak, average and time, so you know when it's time to add load.
Why it mattersFinger strength sets the limit on small holds. Training from your measured peak, not a guess, makes every hang count and tells you when to add load.
-
Average force
Repeaters
Work and rest timers run the set for you. Watch your average force hold up, or fade, from the first rep to the last.
Why it mattersHard routes are a string of hard holds, not one. Repeaters build strength you can keep using move after move, and the fade shows exactly where you start to give out.
-
Rate of force development
Contact strength
Pull hard and fast. Rate of force development on every rep shows how quickly you reach full force, which is what lets you latch a hold instead of bouncing off it.
Why it mattersOn a deadpoint or a far crimp, you get a split second to bear down. If you can't reach full force fast, the strength you have never gets used.
-
Endurance
Critical force
One test shows the force you can keep repeating without burning out. Retest every few weeks and watch your endurance move.
Why it mattersCritical force is the line between pulling you can sustain and pulling that pumps you out. Raise it and you can stay on hard terrain longer before your forearms quit.

Is the app really free?
Yes. The free app saves every session with no limit, shows live force, plays target-load audio cues, calculates rate of force development on every rep, runs peak force and critical force tests, builds unlimited routines, lets coaches assign routines, and exports CSV. An optional upgrade ($29.99 a year or $4.99 a month) adds goal setting, progress over time and history charts.
Do I need a hangboard?
No. Force Board clips between any hold or handle and an anchor. Use a hangboard, a block, a single edge, a pull-up bar, or a PitchSix platform you stand on.
Does it work with iPhone and Android?
Yes. The Force Board app is free on the App Store and Google Play and connects over Bluetooth.
Which model should I get?
Most climbers get the 300. Choose the 300e if you want temperature and humidity logged with each session, and the 450e if you're very strong or plan to do heavy lifts like deadlifts.
How long does the battery last?
The 1000 mAh battery lasts months between charges for most people, and it charges over USB-C.
Is Force Board only for climbers?
No. It was built for finger training, but owners use it for pull-downs, deadlifts, rows, curls and general isometric training. If you can pull on it, it can measure it.
Can I use the carabiners for climbing?
No. The carabiners in the box are for training only. Force Board is a training tool, not climbing protection.
What if something goes wrong?
Force Board has a one-year warranty against defects in material and workmanship. You can also return it within 30 days of purchase for a refund of the purchase price, less shipping. See our return policy, or email team@pitchsix.com.
