No. Vēlox works from pace and heart rate when you have them, and duration when you do not. Power on the bike and CSS in the pool sharpen the picture, they are not required.

Anything that syncs to Strava: Garmin, Apple Watch, Coros, Wahoo, Polar, Suunto. If Strava sees your session, Vēlox does.

Strava connects read-only. Vēlox never posts, never shares, and your training data stays on Vēlox. Delete your account and it goes with you.

Always. Move or edit any session and it stays pinned. The coach replans around your choices, never over them.
