Yesss, no more TP needed, works like a charm on the 235. Thanks!

Great, but crashing on the last rides since 1 week....

Very nice to see hrTSS on my Egde while riding. Exactly like in Trainingpeaks. I did experience an issue and reported it to the dev. The dev almost immediately responded and the day after it was fixed - really cool. Love the app - highly recommended as a TP athlete.

I really want this to work but so far it doesn't. I entered my threshold HR but whenever I start my workout I just see a blue IQ logo with a yellow exclamation point in the field where the hrtss should be. I'm using a Fenix 3 HR with a TRN Run chest strap. I posted on the forum listed in the app description but haven't gotten an answer.

Most useful thing I've downloaded from ConnectIQ so far. I neglected to set my LTHR before my first ride today, which skewed my number low. It looks like it should match the number I have been getting off TrainingPeaks up to now. Assuming this works for me I no longer have any need for TrainingPeaks - yay! This is a critical number for people like me who go back and forth between one bike with a power meter and one without. HrTSS is the only way for me to keep track of training load from week to week. Thanks so much for this wonderful download!

Muy bueno para mantener la gráfica PMC al día si no se tiene potenciometro en la BTT. Very good app for to know the TSS without powermeter.

Sorry, no statistics available yet.
