How challenges work
From the app’s English Help & Guide · Reference release 1.0.13
A challenge tests one food, group, or reintroduction stage using the schedule supplied for that protocol. Many use three rising-dose days followed by rest days; Migraine challenges use a seven-day window with four rest days.
On the challenge detail view you’ll see day-specific guidance (“small dose — fast reactions first”, “rest day — watch for delayed reactions”, etc.) and a “Signals to log” panel showing the timing window for that protocol’s typical reactions.
Choosing what to test
Choose a food and its dose schedule from the protocol group. A saved verdict records that food in that protocol. It does not assign a result to every food in the group.
