Measure your RPM with MyRPM from Tactical Measurements

While various applications have arisen to replace the boxy times used in competition shooting, they offer no ability to analyze the shooting, specifically, the average cadence of the rounds shot. While timers can show specific splits, looking at it longitudinally can be difficult so one is only seeing a small window of the bigger results picture.

Seeing an opportunity to improve upon this is Tactical Measurements, a new company, which has released their application for smartphones dubbed MyRPM, short for “Rounds Per Minute”. The app allows the shooter to visualize their shooting is capable of creating an average Rate of Fire measurement.

App features

+ Find the rate of fire of your automatic weapon
+ Powerful auto-detection of undesired sounds (voices, shells hitting the ground, background noise etc.)
+ Record your shooting sequences
+ Visualisation of shooting sequences in graphs
+ Save details of your measurements (type of weapon, caliber and used ammunition)
+ No additional equipment needed

The app does not have all the other features I would hope for including individual split times, but ROF by itself can be a valuable tool when looking at speeding up shooting. Or, manufacturers may enjoy being able to measure ROF on experimental weapons quickly and easily.

Unfortunately, one is putting their expensive smartphone in the line of fire. High decibel ratings of most guns can cause damage to sensitive microphones. Tactical Measurements recommends the smart phone is kept at least 2 meters / 6 feet away from the muzzle. In other words, don’t leave it in your pocket.

The app is available in both a free (with buit-in ads) and paid version ($20.99). The paid version can save unlimited firing sequences. Both feature advanced auto-detection of undesired sounds to ensure reliable and accurate measurements.

    My iphone got “No results for “MyRPM” 🙁
    I like the idea of easily being able to see the cadence when training/competing.


      Yes, you are right, it´s currently not available on iOS but we are working on it. It´s coming soon. We will announce it on FACEBOOK and on our WEBSITE as soon as the iOS application is available. – stay tuned –

        Thanks! I’ll look for it, I don’t FB.

  • Oaf

    Just ran a mag through an M4 in an indoor range and it measured at 887 RPM. The app seems accurate and is easy to use. $21 to remove the ads and save more than 3 results is crazy expensive.

      I think the price is ok, because it saves you time. And you don’t need any extra equipement.

    “In other words, don’t leave it in your pocket.” OK… I’ve left my cellphone in my pocket many times at the range, even taken it out and lay it next to me while I shoot prone, which put it a mere foot away from the muzzle in a few cases. No problems yet. (Now I’ve jinxed myself and the next time I go to the range my phone will stop working.)

  • $21 seems rather expensive for a single use app with limited utility. I have a hard time picturing that many practical uses for this unless you work on machine guns day in and day out.

    • Thank you for your Feedback Sir,

      The main function is ROF MEASUREMENT, thats right but in our opinion it´s not just a tool for your full automatic weapon, you can also use it to measure your ROF from different weapons like your pistol after changing a part (for example the Connector) on your Glock, or after installing a new trigger group into your AR15. So there are many ways to use our application and we are constantly working on new features so stay tuned for more.

      • Eh, I already have a shot timer for semi-auto stuff.

        But you might be able reach a wider market if you incorporate a more complete shot timer function in addition to your fancy data visualization features. On the surface it doesn’t seem like it would be that hard to add.

        Maybe something like shot coach does with videos, but instead built into a shot timer app where you can label splits with transitions, reloads, movement et al. And then provide analytics for that, might make a bit of a splash to people that aren’t working with machine guns all the time.

        Even cooler if you can use the Apple Watch, so you can keep the phone in your pocket to save to. But the Apple Watch might be able to do all the heavy lifting of listening to the shot, and providing the beep. You can even use the accelerator to feel the shot when being used in a busy range. It would fulfill the promise that the Shotmaxx (which I bought for the bluetooth features) failed to live up to.

        Just spit balling here.

        • Thank you for your help, feedback and input. There are many things we could do and some of them are already on the way.

          Have a great weekend.

    No iOS = no thanks especially if it’s going to cost $21. I’ll wait for the $2.00 knock off that will be out in 3..2..

    That demo video is chock full of awesomeness.

    @TFB – Are you going to do a video review too ?
