In our first tech review column, Jonathan Symcox takes cycling safety app Busby for a spin
BackgroundÌý
Busby, developed by K-Safe, is trusted by thousands of cyclists and has monitored several hundred thousand journey miles since its launch in November 2019.ÌýÌý
The inspiration for the app came when co-founder Barry Green was involved in a serious cycling accident. It uses sensors in a mobile phone to automatically detect a crash or a fall, geolocate the user and alert their emergency contacts.ÌýÌýÌý
Available for free download on any iOS or Android smartphones, it is used by cyclists, walkers, horse riders, runners and road users to predict, prevent, detect and analyse road accidents. It does not collect or store the riders’ data.ÌýÌý
Now active in 32 countries across six continents, the co-founders say it has already saved three lives.Ìý
Tough terrainÌý

I fired up the app during an hour-long ride around the Lee Quarry mountain bike trails in Lancashire. These are known locallyÌýand further afieldÌýforÌýproviding a stern test, with rocky terrain and routes which vary in difficulty fromÌýtricky to downright dangerous.Ìý
GPSÌý
The GPS kicked in without fuss and lasted for the duration of the rideÌýin a fairly remote and hilly setting. When I’ve used exercise apps in the past such as Strava andÌýRunkeeper, the GPS has dropped out when entering the quarry itself, with the result that the sessionÌýautomaticallyÌýends early.Ìý
RecordsÌý
The screen shows the distance you have ridden, which isÌýfairly accurate, although it doesn’t store your activityÌýfor future referenceÌýas an exercise app would.ÌýBut then, that’s not its purpose.Ìý
MountedÌý
I mounted my phone on the frame of my bike so I could see how the app updated throughout.ÌýThe only frustration was when the screen went toÌýsleepÌýand I had to stop to bring it back up.ÌýHowever,ÌýBusby’s tagline isÌý‘Safety in your pocket’ –Ìýit is there as a safety mechanism, not to keep track of how far you have ridden.Ìý
G-forceÌý
The key feature of the app isÌýhow it tracks the g-forcesÌýacting uponÌýyour phone, with the idea that if you are in an accident,Ìýit willÌýidentify thatÌýthroughÌýinterpretation ofÌýtheÌýimpactÌýcreated.ÌýDuring the ride it could tell when I was cycling; when I stopped, it took a few seconds to sense that I had become still; and when I threw my phoneÌýinto a hillside, it knew something was amiss.Ìý
EmergencyÌý

The screen turned red, the phoneÌývibratedÌýand it gave me a clear 30-second countdown to cancel the sending of a message to my emergency contacts. Having mentioned this to my wife earlier, I let the message go throughÌýand it did so, smoothly.Ìý
False alarmÌý
The one downside to using the app was when I took the bike down aÌýlong andÌýprecarious ‘black’ trail, the shaking of the bike again triggered the alarm. AsÌýI was concentrating on staying in one piece rather thanÌýlooking at the appÌý– and could not feel the vibration –ÌýmyÌýwife was again notified. You can extend the 30-second delay, should you wish,Ìýwhich would have helped here.ÌýAnd better safe than sorry…Ìý
Extra servicesÌý
Busby FlareÌýallows users to send out an SOS message to surrounding users within a five-mile radiusÌýand alsoÌýconnects them to nearby bike stores.ÌýThe premium version of the app allows for more emergency contacts to be added.ÌýGroupRideÌýallows users to set a safety radius around everyone in their group and receive a notification if someone falls behind.ÌýDifferent activities can be selected, including walking/hiking, running, horse riding, motorbiking and skiing, although these were not tested.ÌýA recent update also rewards users by offering coins per mile which they can spend on in-app discounts or enter monthly competitions. Fingers crossed for that Go Pro 8…Ìý
Busby is available to download for free atÌýÌýor by searching for the app in your app store.Ìý
