Wahoo Fitness 4+

I’ve used other gps in other sports they did ok. Wahoo has stepped up and modernize the game without making it look and feel like a game. Hats off for that.
The only irregularities I see with GPS is one I’ve seen even in the service and basecamp units. Civilian GPS units are not as precise as thousand dollar units. Basically if you have a 25 foot proximity value in your GPS reading you can be anywhere within the proximity. Another important bite is, GPS needs three satellites to start calculating where you’re at at any given moment. When one of those satellites change the information changes just enough that you may think your gps device is acting up or broken. ITS NOT IT’S THE GPS system and fact “it’s Way better than it was 10 years ago”
I feel for my investment in Wahoo Devices to take cycling with me that they are the best. The service and support that’s been is top notch. Thanks Wahoo

I bought the Cadence & Speed sensor pack a couple years ago. Setup of the sensors and app went fine. As a long-time Strava user, I wanted to compare the accuracy of Strava vs Wahoo. I had to fuss with the rear wheel diameter quite a bit from the 700x23 default before the two apps were within 1~2% of each other for distance.
Then, the app began acting up after an update. Wahoo would drop out every few readings from the sensors, so a 19mph average pace ride would display as 14mph average over ~2/3 my actual distance. Sadly, the Strava app (at the time when it used to connect to cadence & speed sensors) was spot-on using the same sensors.
I reached out to Wahoo support, and they kept in touch with me for months on the issues. Eventually, I was informed of an update that would fix my issue. Sure enough, the update fixed the sensor connections.
Now, Wahoo’s altitude gain is WAY off in the app based on the GPS and sensors on my phone (1st gen iPhone SE). So, a ride with 1,439’ of climbing (per Strava) displays as 5,401’ in Wahoo. Here’s where that really stinks - if I upload my Wahoo rides to Strava, Strava corrects the altitude, and the calculation results in a ~2/3 decrease in my estimated power average.
I cannot find any way of getting these two apps to work together. So, I just use both apps simultaneously - Wahoo to display metrics during my ride and Strava to log it.

Started off bad as I accidentally clicked on the screen and set a lap time of 1 second, don’t know how but after 187 laps I stopped to figure it out. Those popups are a treat. Went to the work out settings and changed the metric to 1 mile. Started the app again and wouldn’t you know it still had laps set to 1 second. I even reset the cycling work out to defaults. Restarted the workout and was still receiving 1 second popups. Only fix was to turn-off the auto lap indicator.
So then I go back after ending and restarting the workout but it defaulted to running and I kept getting pace vs speed in my dashboard. Stopped the work out and restarted and it was set to cycling. It still showed pace. Stopped and started again and selected running and re-selected cycling and finally speed showed rather than pace.
I used to use map my run but apparently they do not support wahoo sensors since underarmour took over. Can’t find any documentation on that but assume they wanted money or wahoo figured their app would be better. I liked my wahoo sensors better working out with map my run. I will try it some more but this app needs some serious work. Reset the lap after each work out and don’t leave it perpetually in memory. And fix the issue with selecting the workout making sure the proper metrics and displayed.
