A steadier connection, and a ride that picks itself back up:
- Lost your trainer mid-ride? The ride now resumes on its own the moment it reconnects — until now only the automatic pause ever happened.

Bring the whole family along — and a lot more:
- Family Sharing: the subscription and the lifetime unlock now come in Family versions, shared with up to five family members.
- Pay monthly on the yearly plan: choose a monthly payment with a 12-month commitment instead of paying for the year all at once.
- One-tap trainer shortcuts: nine slots you set up yourself, each pairing a mode with a target — ERG watts, resistance or slope. Tap one mid-ride and the trainer takes it straight away.
- A roomier ride screen: when there's space the trainer controls sit as their own block instead of sharing a page with the chart, and a new preference lets you always show them or keep them tucked away.
- Truer trainer control: the mode picker offers only what your trainer really supports, a mode that stops being supported no longer stays stuck on screen, and another connected sensor can no longer overwrite your trainer's capabilities.
- A cadence sensor you assign is now actually used for cadence, the way an assigned power meter already was.
- Home shows where you stand: how many free rides are left this month, and a clear warning if Health access is missing before a ride goes unrecorded.
- Delete a ride straight from Sessions.
- Calmer screens: the music player steps aside when nothing is playing, and iPad gets its ride charts and layout sorted.
