Does Slopes: Ski & Snowboard work on iPhone Duo?
Yes. Slopes: Ski & Snowboard's App Store page says it supports iPhone Duo, so the update is out. FoldHunt's editor hasn't seen it running yet.
- App Store confirmedThe developer, posting as Slopes on X on October 10, 2026, with a video of Slopes on iPhone Duo closed and open, marked coming soon (@slopesapp on X). The App Store's release notes for version 2026.16, released on October 9, already say Slopes is optimized for iPhone Duo: a compact interface with a smaller map folded, and larger full-screen maps open. The seller is Breakpoint Studio LLC.
Adapted for the fold
- Closed · Outer display
Hit record with one hand
Closed, the cover holds the recorder, a small map and your day's runs and stats, all reachable with one hand.
- Open · Inner display
The whole mountain
Open flat, the trail map fills the screen and the resort guide, with trails, food and restrooms, sits in a panel beside it.
About Slopes: Ski & Snowboard
Slopes records your ski and snowboard days, your speed, vertical and runs, and replays them on a 3D map of the mountain. In its iPhone Duo video, the closed cover is a one-handed recorder with a small map, a list of runs and trip plans, and opening the phone turns it into a wide trail map with the resort guide beside it. Closing it again takes you back to the compact view.
