8. Supervisor mode

8.1 What it is

Supervisor mode turns one device into a range controller: several shooters and several targets, driven from a single phone or tablet, with one synchronized sequence, per-shooter live scoring, and the range commands played once for everyone.

It is enabled by a grant on your Fastmark account (§4.7): the account carries a supervisor validity date and the list of registered targets — the serial numbers of the targets you may drive simultaneously. Both are shown in the "Supervisor mode" card of the User page. Without the grant, the app is limited to one shooter row and one target.

8.2 Several shooters

With supervisor access, the "Shooters" list on the New-session page gains controls:

• "+" on the first row adds a shooter — added shooters appear as "Guest" entries, each with their own target badge, result card and scores;
• "−" removes a shooter (their target is released automatically).

Every shooter gets their own results everywhere: result cards on the series screen, per-shooter cards and totals on the session page, per-shooter details pages. The eye icon on a result card filters the whole screen to that shooter when things get busy.

Naming a real shooter instead of "Guest" — any signed-in account (supervisor or not) can put another account's shooter in a row of the list:

1. Long-press the row to open the "Select shooter" dialog. It lists your own shooter first, then every shooter already shared with you, most recently used first — tap one to select it.
2. To add someone new, the other person opens their User page and taps "Show my code" in the "Shooter select" card (§4.2). The app displays a 4-digit code with a countdown — it is valid for 10 minutes.
3. Type that code in the dialog's "Enter a share code" boxes (this step needs internet). The shooter is added and selected; an expired or mistyped code shows "Invalid or expired code".

A code has to be exchanged only once: the shooter stays available in the dialog afterwards, and the sharing works both ways — each of you can add the other. Their results appear under their own name on result cards and in their own account's statistics.

Withdrawing the sharing: Settings → Others → "Revoke" removes your shooter from all accounts you shared it with, after the confirmation "Remove your shooter from all accounts you shared it with?" — the button then reads "Access revoked". To share again, hand out a new code.

8.3 Several targets

The one-target-per-device rule is lifted for targets whose serial numbers are in your registered targets list: assign one target to each shooter through their badge, exactly as in §3.3 — the badge of each shooter shows assigned/required and must be green before launch.

During the series the app runs all targets on one synchronized clock: phases change together on every target (within a few milliseconds), and each shot is credited to the shooter whose target reported it. Formats that require more than one target per shooter show a badge like 0/2; assign that many to the shooter.

If one target fails or powers off mid-series, only that target is released — the rest of the line keeps shooting (§6.7).

8.4 One shared target — relay shooting

Some formats put several shooters on a single target, taking turns. In these sessions only the first shooter's badge carries the target; during the series the app attributes the shots in rotation, so each relay's shots land on the right result card. The result cards tell each shooter where they stand; fire in the agreed order.

8.5 Exclusive mode — a device bolted to one firing point

Exclusive mode dedicates a device to a single target — typically a tablet permanently installed at one firing point of a supervised range, which must ignore everything happening on the other lanes.

• Enable: User page → "Supervisor mode" card → expand "Registered targets: " → tick the checkbox of the target this device belongs to. (One target only; the other checkboxes disable. The list's own caption says it: "Selecting a target will turn this device into a passive display for series shot on this target.")
• Effect: the home screen is replaced by an "Exclusive mode" notice with "Target: " and the reminder "You can return to normal mode by deselecting the target on the user page (side menu)." The device now ignores sessions pushed onto other targets: it auto-opens only series running on its own target (§4.5).
• Disable: open the menu → User page → untick the target. The normal home screen returns.

The setting is per-device and survives app restarts.
