HSK Chinese practice with the character above the fold and the writing box below
Does MandaDeck work on iPhone Duo?
Yes. MandaDeck'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, in the App Store description, which has a section on iPhone Duo, and in the release notes for version 1.9.19 (released October 11, 2026): held half-open like a book, quiz answers and two-column screens such as Record now stay clear of the fold. The App Store seller is hideo endo (id 6761324480). The store's screenshots show the iPhone and iPad, not the Duo.
Adapted for the fold
- Standing · Hands-free
A word card that stands
Closed and stood on its side, the word detail becomes a single card that moves on to the next word with the audio during auto-play, and the screen stays on while it plays.
- Open · Inner display
The word list beside the word
Open, the word list sits beside the word you're reading, and turning the phone sideways spreads the Practice, Record and Reference tabs into two columns.
- Book · Partly folded
Write below the fold
Half-open, Stroke Order practice puts the character on the upper half and the writing box on the lower half, so you never write across the fold. Quiz answers and two-column screens such as Record stay clear of it too.
About MandaDeck
MandaDeck teaches the 5,000 words of HSK levels 1 to 6 with spaced repetition, listening, writing and pronunciation practice. Its App Store description sets it out for iPhone Duo. Closed and stood on its side, a single word card moves on with the audio during auto-play. Open, the word list sits beside the word you’re reading. Half-open, Stroke Order practice puts the character above the fold and the writing box below it, and since version 1.9.19 quiz answers and two-column screens stay clear of the fold too. Opening or closing the phone keeps the word you were listening to and the practice you were on. There are no pictures of it on the Duo yet.
