Frequently asked

Which devices does it run on?: iPhone and iPad, with iOS 17 or later. On iPad the list and the page you open sit side by side.
Does it need a signal?: No. Everything in the app works with no signal at all, including the region and the sunset time. The only thing that needs a connection is buying or restoring the full version.
What's free, and what does the full version add?: Free: 55 of the 73 picture cards,10 of the 19 how-tos, and all of Safety. The full version is a one-time purchase ($4.99 in the US) that adds the other 18 cards, 9more how-tos, and the Challenges tab: a troop inventory, "Assign me a method" and a timed patrol contest. There is no subscription and nothing else to buy.
Where did my purchase go?: Purchases belong to your Apple Account, not to a device. Tap the gear in the Field Guide, then Restore Purchases under Full version. If it still doesn't appear, write to us.
Can my family use it too?: Yes. The full version works with Family Sharing, so everyone in your family group gets it without buying it again.
I asked to buy it and nothing happened.: With Ask to Buy, the purchase waits for the family organizer to approve it. Once they do, the full version unlocks by itself, the next time the app is open.
Why does it ask for my location?: To show the tinder and fuel that grow in your part of the US, and to work out when the sun sets for night mode. It uses your approximate location only, and it never leaves your phone. You can say no and pick a region in Settings instead. See the privacy policy.
Some cards are missing.: The Field Guide hides cards that don't usually grow in your region. Tap Show everything at the end of the list, or turn it on in Settings, to see every card, for planning a trip. Outside the US, use Show everything.
How does night mode work?: Night mode turns the app red on black, to keep your night vision around the fire. Tap the moon on any main screen to turn it on or off, or set it to come on at sunset in Settings. iOS draws the clock, battery and keyboard itself, so those don't turn red. For the whole phone, turn on the red Color Filter in iOS Settings › Accessibility; the app's Settings explains how.
Why did my checkmarks disappear?: The "How do you know it's done?" checks clear at 2 AM each day, so every campfire starts fresh.
Is this a replacement for training?: No. It's a field guide to carry with you. Follow your troop's rules, camp rules and any fire restrictions where you are.
