I’ve used all three major indoor cycling apps extensively — Zwift for two winters, TrainerRoad for a focused 12-week training block, and Wahoo SYSTM when I wanted something different. They’re all good. They’re good at different things. Here’s my honest take on each.
Why Bother With an App at All?
Because staring at a wall while pedaling is miserable, and you’ll quit within two weeks. I tried the “just ride the trainer with music” approach my first winter. Made it to mid-January before the Kickr became an expensive clothes hanger. The apps give you something to focus on — a race to chase, a workout to follow, a number to hit. That structure is the difference between actually training and just suffering pointlessly.
Smart trainer integration is the other big deal. The app tells the trainer what resistance to apply, so you don’t have to think about it. Load up an interval workout and the trainer ramps the resistance up for the hard parts and backs off for recovery. It’s like having a coach who controls your legs.
Zwift: The One Everyone Knows
Price: $14.99/month
Best for: People who need motivation, social riders, anyone who gets bored easily
Zwift is basically a cycling video game. Your little avatar rides through virtual worlds — Watopia (the main one), London, New York, Yorkshire, and several others. Other people’s avatars are riding alongside you in real time. You can draft off them, join group rides, enter races, and earn fake equipment upgrades that somehow still feel satisfying.
I got genuinely addicted to Zwift racing my first winter. Wednesday night crit series, starting at 7pm, 30 minutes of absolute suffering against people I’d never met. My FTP went up 15 watts in two months because I kept showing up to get my butt kicked and slowly started kicking back.
The structured workouts exist too, and they’re fine. But the real draw is the social/competitive element. If you’re someone who’ll skip a solo trainer workout but won’t bail on a group ride, Zwift is your app.
Works on Apple TV, iOS, Android, PC, and Mac. Apple TV is the easiest setup if you have one.
TrainerRoad: The No-Nonsense Option
Price: $19.95/month or $189/year
Best for: Structured training, goal-oriented riders, people who want to get faster efficiently
TrainerRoad is what you use when you’re serious about getting faster and don’t need a virtual world to make it happen. No avatars, no scenery, no gamification. Just you, your power numbers, and a workout that tells you exactly what wattage to hold for how long.
Their adaptive training feature is genuinely impressive. It adjusts your training plan based on how you perform in each workout. Crushed your sweet spot intervals? It bumps up the difficulty next time. Struggled with VO2max efforts? It dials them back slightly. Over a 12-week block, the progression felt personalized in a way I didn’t expect from software.
I used TrainerRoad to prepare for a hilly gran fondo and hit my goal time by 8 minutes. The structured approach worked. But I’ll be honest — some of those Tuesday evening threshold sessions were soul-crushing without anything to look at except a blue bar on a screen. I’d queue up a podcast or Netflix on a second screen to survive the longer workouts.
Wahoo SYSTM: The Middle Ground
Price: $14.99/month or $99/year
Best for: People who want structured workouts with video entertainment, multi-sport athletes
SYSTM (formerly The Sufferfest) overlays workout targets on real cycling footage. You’re watching a mountain stage of the Tour while the app tells you to hit 280 watts for the next 4 minutes. The workout names are dramatic — “The Hunted,” “Nine Hammers,” “Violator” — and the sessions are genuinely hard.
It’s less immersive than Zwift and less data-driven than TrainerRoad, but it hits a sweet spot between entertainment and structure. The $99/year price is also the best value of the three if you’re paying annually.
I used it for about three months and liked the variety. They also include yoga, strength training, and mental training sessions, which is nice if you want a more complete program than just pedaling.
Which One Should You Pick?
If you need motivation and community to show up consistently: Zwift. The gamification and social features keep you coming back.
If you want the most effective structured training and don’t care about entertainment: TrainerRoad. It’ll make you faster, period.
If you want structured workouts with something to watch and the best annual price: Wahoo SYSTM.
All three offer free trials — Zwift gives you 7 days, TrainerRoad 30 days, SYSTM 14 days. Try them during a rainy week and see which one you actually enjoy using. The best training app is the one that gets you on the trainer consistently, not the one with the most impressive feature list.
