Before we dive into the details here, I assume you have a sports watch. If you don’t, please hit pause and sort that first and then come back. To name a few: Garmin, Polar, and COROS each ship with solid ecosystems such as Garmin Connect, Polar Flow, COROS Training Hub. On their own, let me be clear, they’re plenty for tracking, basic planning, and long-term trends! That said, a few third‑party apps can add polish, community, or deeper structure, here is watt I learned on that topic.

Strava is the obvious first stop. The free version (as it stands now) is enough for most people: activity feed, basic segments, route sharing, and a bit of social accountability. It keeps training playful without locking you into a subscription. If you later want live segment chasing or detailed training analytics, you can test Premium, but you don’t need it to get value. I like the route-making functions of the Premium version, which helps me find good routes quickly as I travel a lot for work and therefore need to quickly figure out what route would be nice to run. Pure luxury of course, not a necessity.

When I’m on a specific plan, TrainingPeaks becomes non‑negotiable. Clear calendars, planned workouts that sync to your watch or bike computer, and honest feedback on whether you hit what you intended. If you have a coach ,they can also remotely and directly dive through all your data and updates which is next-level cool. I can do without Strava; I can’t do without TrainingPeaks when I’m chasing a goal. Use the free tier to get started; the paid tier unlocks deeper metrics, but the real win is the plan and execution loop.

If you ride indoors, Zwift and Rouvy make winters less grim. Zwift turns the trainer into a group ride or race with structured workouts baked in; Rouvy leans into real‑world video routes and steady endurance. Both integrate smoothly with smart trainers and bikes, both sync your rides to your watch ecosystem, and both make long aerobic sessions pass faster than staring at a wall. Both are owned by Zwift nowadays, just fyi. If I have a structured workout scheduled that is set to take less than one hour, almost guaranteed I will do it indoors on Zwift.

Another one worth a look. For routes and navigation, Komoot is excellent, especially in Europe, for planning rides and runs with surface types and turn‑by‑turn cues that transfer to your head unit or watch.

Keep in mind, these subscription costs (in case you would take the premium version of any of these) add up quickly. Choose wisely. Add apps that solve a real problem: plan execution, indoor sanity, route quality, or safety. If an app doesn’t earn its keep in a month, delete it, unsubscribe and see f you miss it.

Watt I Learned

Your watch ecosystem covers most of what you need. Strava (free) adds community, TrainingPeaks adds structure, and Zwift/Rouvy add winter sanity for indoor running and biking. Everything else is seasoning, use it if it makes your training simpler, safer, or more fun. These are just the apps I happen to use, there are of course many more out there to explore!
