User reviews

Not capturing the sound.

I have my range on the backyard in a Fl suburb. The app doesn’t catch the sounds. Help

Love it!

So far I’ve shot around 200 arrows using the app. It is consistent however, it runs about 20fps slower than my Garmin chrono. I would like to see an option to force match the apps readings to my known good chrono. I absolutely love this app and I’m looking forward to see how it improves over time. Well done!

Doesn’t work

I would have loved this to work as it should but when I downloaded it doesn’t fit my screen properly. Stuff cut off on both sides. Also doesn’t pick up the shot or arrow hitting target. If I clap twice it picks that up and gives me a “speed” but cannot hear my bow or target for some reason. If someone can tell me how to make this work I’d love to change my review

Excellent Alternative

For us backyard archers, this is an excellent alternative to an expensive Chrono. Due to the limited distance I have available (15 yards), this is a great way to gauge my fps. I have 8 bows that I have measured with a cheap chrono and this is much more convenient. The accuracy is within 5fps of the cheap chrono and that is good enough for my use. I really like being able to keep my different bows and arrows tagged in the app and the sessions feature. I would love a way to export the data so I could keep it in a spreadsheet for easy comparison.

Works but huge flaw

It works great when it’s calm out. If there is any wind it will pick up on that and read wrong. It will also give false shots that didn’t happen. It reads a bit slow compared to a Harmon zero but that’s because the Harmon reads initial speed and this reads average.
