Signing in is what makes your inspections more than files on one device. With a single tap — Sign in with Apple — every inspection you capture is backed up, available on your other devices, and ready to share with a shop, a customer, or an analyst. There is no new password to create or remember, and no separate account to set up: your Apple Account is your Jug Scope account.
This section covers why you sign in, exactly what Apple does and does not share, how the first run differs for owners and shops, what to do if the sign-in does not finish, and where to find your account details later in Settings.
For owners — Signing in is your safety net. Your inspection history is backed up and follows you to a new iPad or iPhone, so the record you built up over years is never trapped on a single device.
For shops — Signing in establishes your shop's identity in Jug Scope — the foundation for sending finished inspections to customers and exchanging them with other shops (see §6, Sharing & Analysis).
2.1 Why sign in
Three things depend on being signed in, and you get all of them from one tap:
- Backup. Your inspections are saved to your account, not just this device — so a lost or replaced phone never means lost work.
- Multiple devices. Start on the iPad at the hangar, pick it up on your iPhone later; your inspections are there on both, secured by your Apple Account.
- Sharing. Sending an inspection to your shop or a customer, or receiving one shared with you, runs through your account (see §6, Sharing & Analysis).
You sign in once. From then on Jug Scope recognizes you automatically each time you open the app.

2.2 What Apple shares — and what it doesn't
Sign in with Apple is built around your privacy, and Jug Scope is built to respect it. Apple handles the authentication entirely: it confirms who you are without ever handing your password to the app.
- We never see your password. Apple authenticates you; the app only receives confirmation that the sign-in succeeded.
- Jug Scope never asks for your name. The first time you sign in on a device, Apple asks whether to share your email address or hide it with Hide My Email. Either works — the screen says so before you tap.
- Your Apple Account is the only identifier we use. It is how Jug Scope ties your inspections to you and how it finds your existing account if you reinstall the app.
That last point matters: because your Apple Account is the key, you can delete and reinstall Jug Scope, or move to a new device, sign in again, and find your account waiting.
2.3 First run for owners
For an individual owner, getting started is the simplest possible path: open the app, tap Sign in with Apple, and you are in. There is no code to enter and nothing to look up. From there you add your aircraft and start inspecting (see §7, Guide for Individual Owners).
2.4 First run for shops
A shop signs in exactly the same way — Sign in with Apple — and that sign-in establishes your shop's identity. From there you can create your shop, invite your mechanics, and send and receive inspections. The full walkthrough is in §6.2 and §8, Guide for Shops.
For shops — Use the same Apple Account consistently for your shop so all of your inspections, customers, and shared work stay under one identity.
2.5 If the sign-in doesn’t finish
Signing in is the only step between the welcome pages and the app: there is no form to fill in and no code to enter. If you close Apple’s sign-in sheet before it finishes, the Sign in to Jug Scope screen stays put and tells you so in one line under the button: “Sign in with Apple didn’t finish. You’ll need to sign in to use Jug Scope. Tap the button to try again.” Tap Sign in with Apple again whenever you are ready.
If the sign-in fails rather than being closed, the same spot shows what went wrong in plain words — for example that you are not connected to the internet, or that Apple couldn’t complete the sign-in — and the button is ready for another try. Tapping it clears the message.
Tip — Always use the same Apple Account. It is the only identifier Jug Scope uses to find your account, so the same Apple Account brings your account back on a new device or after a reinstall.
2.6 Your account in Settings
You can see and manage your account any time from Settings (open it from the Home screen toolbar). The Account section shows Signed in with Apple and, if Apple shared one, the email address on your account.
To reach the cloud features and sign out, open Jug Scope Cloud from Settings. There you will see your signed-in status, a Sign Out option, and Join a shop with a code (see §6.2).
Caution — Signing out disconnects this device from your account and its cloud features until you sign back in. Your inspections that are backed up remain safe in your account; sign in again with the same Apple Account to restore access.
