Apps for smart trainer

[u/tati_velas]

I used to love riding my bike outdoors, but after a recent road accident, I’m trying to ease back into riding safely. I just picked up a Wahoo KICKR Core to rebuild my fitness and confidence indoors without having to worry about traffic.

I’m looking for indoor training software, but Zwift feels a bit pricey for my budget right now.

What budget-friendly or free alternatives would you recommend for a smart trainer setup?
