• Every daily safe
• Unlimited practice safes
• The share grid, your logbook and your rank
• The home-screen widget, and a morning reminder if you turn it on
• The whole first machine: all 7 of its parts and the first 7 letters

There are no ads and no subscriptions.

The Workshop Kit is one optional in-app purchase, bought once: $4.99 in the US (the App Store shows your local price). It unlocks:

• Every machine after the first, including new ones as they are added
• Every letter after the seventh, including new ones
• 3 desk themes, 2 finishes and 3 dial faces
• The glass practice safe

Without the Kit you lose nothing you have earned: after the first machine, new parts wait in a crate and new letters stay sealed. Buy the Kit and everything opens at once.

Tap the gear on the daily screen, then Restore Purchases. It is in the Shop too. Use the same Apple Account you bought the Kit with; restoring is free and works on a new iPhone or after reinstalling.

Try Restore Purchases first, and check that you are signed in to the App Store with the Apple Account that bought it. If it still isn't there, email us; please don't send payment details.

Not at the moment: Family Sharing is off for the Workshop Kit.

Apple handles every refund, at reportaproblem.apple.com. After a refund the Kit stops unlocking new machines and letters, and its desk themes, finishes, dial faces and glass safe go back to the standard look. Parts and letters you had already opened stay open.

Turn the dial with one finger and watch the needle: it rises as you near a wheel's number. Tap the stethoscope and sweep the dial to listen. A snick means you found the number and a lamp lights; a tick is another wheel's number, chalked on the dial at that number with the wheel's numeral (I, II, III); a tonk is a decoy, chalked on the dial with an x. Light every lamp and the door opens. Par is the number of listens a sharp safecracker needs; try to match it.

At midnight, your local time. Each day has one daily safe; practice safes are unlimited.

Yes. Every cue shows on screen, so Tumblewright can be solved by sight alone. Sound and haptics add the feel of a real dial, and you can turn each off in Settings (the gear).

If your iPhone's date is set more than a day behind the last safe you played, the daily safe waits and you can still play practice safes. Set the date back to today and the daily returns.

An optional reminder, off unless you turn it on: at most one a day, in the morning. If you ignore three in a row it turns itself off. Change it under the gear, or in iOS Settings, Notifications.

Touch and hold an empty part of your Home Screen, tap the add button, search for Tumblewright, and add the small widget. It shows whether today's safe is open and your listens against par.

Tumblewright is made for iPhone. An iPad can run it as an iPhone app, in a phone-sized window.

Progress is kept only on your iPhone, so deleting the app removes it, unless you restore the iPhone from a backup made before. The Workshop Kit itself is never lost: restore it from the gear.

No. No accounts, no analytics, no ads and no tracking; your workshop stays on your phone. The details are in the privacy policy.
