Send me an email to Roberto.viola83 at Gmail.com and I will help you! Writing a bad review without even contacting the developer is not useful!

If You Have A Bike Radar And An Apple Watch …

Then you simply HAVE to buy this. It gives you a lifetime membership for a few quid and for me-it’s an essential purchase. There is also a free IPhine version but this is the one to get. Switch to ‘Classic’ mode on the Watch. And you get three tones to indicate the proximity of upcoming traffic. You don’t even need a Garmin Edge unit. Beebeedoop for distant. Deedeedoop getting nearer. And Deedoop for imminent. Future versions will have a Ding! 🛎️ to notify the All Clear There are three other modes but for me the Classic is the most intuitive. My only ‘gripe’ being that instructions could be better. But I’ve sussed it now. Also the guy (Roberto) who made the App replies fast and very interactive to suggestions. Recommended!

Thanks!

No bike computer needed!

I bought the new Lezyne radar light. I liked the idea of radar but I really didn't like the idea of a big complicated bike computer on my handlebars. I wrote to Roberto to ask if his app worked with this new radar. It didn't, but within a week he had it working! all that I need- a little beep when there's a car behind you and a different sound when it's all clear. The watch face has an easy to read at a glance display - in addition to a number it is color coded, green for clear and yellow or red for a car back. It even syncs with workouts to record your ride. Thank you Roberto!

Thanks

Excellent with Apple Watch

Super pleased with the app. First test ride today with watch paired to rvr315 - easy no fuss pairing , just turn on the radar , select ARadar on the watch and you are ready to roll . It works great , with my side mirror all I need is the haptic alert on the watch. When I got back I adjusted watch haptic setting to “prominent “ just so it’s very obvious , I rarely ride in roads with a lot of traffic so this works for me.

update 4/6/24: affer downloading the new version i experienced a couple of glitches - roberto super helpful and issues promptly resolved . thanks!

Happy customer but got one suggestion

I am a happy customer of your apple watch app but thought I would send you one suggestion.

There have been a couple of occasions where either my Garmin radar went out of battery in the middle of the ride, or I moved out of Bluetooth range (such as to go to a restroom during a ride), or, for some mysterious reason, the connection was lost to my watch.

The problem is that when this happens, the recording of the ride stops, and Apple workout picks up, which messes up what gets uploaded to Strava. Is it possible to keep recording the ride even though the Garmin radar has lost connection for one reason or another?

Update - Roberto replied to me and pointed out there is an "auto stop" setting on the watch that can be used to control the behavior, which addressed my issue.
