Carbon Drive
What about tension? Is my tension too high or too low? Don’t have a proper tool? Well now we’re putting one of the easiest and best tension tools right into your Android device. Just pluck your belt like a guitar string, and use the microphone on your phone to read the frequency that it’s vibrating at. Compare your belts frequency to the included chart to see if you need to adjust the tension.
-Find key parameters of your drive such as speed ratio and center distance -Change belt length or sprocket sizes to better suit your riding needs -Check out what sprocket sizes, mounting options, and belt lengths are available in our catalog -Check tension with our frequency measuring tool

The old app was great. Pretty accurate readings were given. Since the new update/redesign the app is pretty garbage. I can get readings, but the timeframe of when I actually get the reading or what it's getting it from mis random. This is coming from a zero tech who works with this app pretty frequently. It takes me twice as long to get a belt tension done because I can't tell what the hell this app is reading for sound.
Completely useless app. Frequencies are all over the place using the exact same position and finger and strength. Closing and opening the app and changing literally nothing about the bike and you can count on getting wildly different results. I wouldn't rely on this app to tune anything. Also whoever's idea it was to kill the app instantly in the background so you have to find and open it again and watch the dumb video that automatically should never develop another app again.
You get what you pay for, and that about sums up this free app. That and "utterly unreliable & inaccurate." The app fails on so many points, demonstrating why tech is a false hope: User must "strum" the belt drive with phone mic pointed to belt. Even then, phone doesn't register 90% of strums. This with a new phone with mics on either end in a silent room. When the app does register, values are all over the board. 93, 22, 110, 54... Statistically, "quality" is the absence of variation around a goal (in this case actual tension). With such wide variation, we have a clear lack of quality or reliability. The app does not allow personalizing the app for your bike(s) (aside from turning off that awful video). Instead you get a generic tension chart that is ambiguous if you have gear box-driven mtn bike. Since proper tension IS important, I gave up on this app in favor of their Kriket device to measure tension. While simplistic, it IS reliable and I believe accurate. And my thumb which does the strumming thanks me for doing so.
I dont know what the bad reviews are talking about. I almost deleted this app before trying it, but after plucking my Zero's drive belt three times using a wrench I got 59 Hertz every single time.
Not worth having, even for free. If and when it picks up a signal it can be half or twice the previous one with nothing changed on the belt position. Any scientist will tell you that an erroneous reading is worse than none at all as you just can't trust it. A mechanical cricket tool is probably a better bet.
This app doesn't work. It's probably not even devs fault. The sound belt makes is very quiet and this app doesn't hear it. It's possible that it was tested and found functional in a very quiet lab environment. It doesn't work in the real world.
Used to be I could click open the app, instantly measure tension on my bike, and go. On the new one I have to wait for a little advert movie to play, then tell the app Im using it on a motorcycle. EVERY TIME! What was a quick and useful tool now puts two barriers between you and the data you want. Also the results are now much less repeatable. I guarantee this "upgrade" was approved by some office dweller somewhere who never actually works on things and doesnt use this app.
thought I could save some money ... don't even think about it. Either go to your local bike dealer or get one of the real tools. When I first assembled my bike it seemed to work but now my fingers hurt like crazy but the app gives me - in the rare cases it shows anything - values between 17 and 220. I can just assume that something I assembled later makes some side noise that disables the app from working properly. This guess does not help anything however - it just does not work ...
The new update has an unskippable video that I have to watch every time I use the app. No longer works for reading belt tension. A different spectrum analyzer app works fine however. Also keeps running in the background and using microphone.
Worthless. Most of the time it doesn't doesn't pick up the frequency. When it does pick it up sometimes the readings are the same or very similar and other times they are very different. Tried the app on multiple phones with the same issues.
I work with riese and muller everyday and this app was a life saver for tension on the carbon drive belt. But since the new update it doesn't pick anything up. Go back to the old app witch worked fantastic
This app will not open and run on my stock Android 9 pie phone. Bummer. Now it's working on Android 10 but frequencies are all over the place.....not sure it's really to be relied on and I'll try other apps
Didn't work. Downloaded it, tried to use it, but it wouldn't register the frequency. Soundwave bar was moving but hardly ever registered the value. Uninstalled it
Very rarely displays a frequency and then it's wildly fluctuating. This app simply doesn't work. Uninstalled.
This app has never really worked in any practical way. I tension belts by feel and that works just fine for me. Don't waste your time here.
I'm new to belts gate drive and my belt was slipping on my new bike.. after a bit of you tube and googling I found out how to tension and used this app to do so.. belt drive is now spot on!
Annoying video you can't skip, scary ToS and permissions. Just use an instrument tuner app that shows Hz .
Won't pick up the belt that is 1cm away but can hear the birds chirping outside. Unfortunately I need this app for work.
I couldn't get the app to work, so had to buy an expensive tension-checking device
Samsung S9 random readings.. need to pluck numerous times for one reading
Garbage! Doesn't hear most of the time.
Doesn't work, only shows up if I yell at it.
Does not work on xiaomi mi 8
Gates should not be selling belt drive bikes parts. They are not yet ready for the public.
Unusable and anying app
Doesn't work, no way to tell what the measurements are
Can't get a reading
A bit hit and miss, but in the absence of anything else it's possibly better than nothing. Rarely provides repeatable frequency measurements at the same belt position, but I'm averaging out three or four readings taken at the same belt position, and then rotating the crank to move the belt along a few inches for the next three or four frequency measurements and so on. Overall, averaging the measurements at each point seems to provide a better indication of belt tension.
