Last updated: June 6, 2026 (app version 1.6.0)

[ GETTING HELP ]

For support, questions, or bug reports, message us through the RCT Authority contact page. When reporting a problem, please include:

App version (Command Center → bottom of screen, or the splash shows INITIALIZING FIRMWARE V1.6.0…).
iOS version (Settings → General → About → iOS Version).
Device model (Settings → General → About → Model Name).
Whether you used a gamepad (and which one).
What you expected vs. what happened.

[ FIELD MANUAL ]

The in-app Field Manual covers normal operation: swipe up from the meter face → System Documentation → Open Field Manual. The same content ships inside the app.

[ QUICK TROUBLESHOOTING ]

Splash screen lingers. Tap anywhere on the splash to skip the boot animation.
Taps on the meter do nothing or the wrong thing. The meter face is split into invisible halves: the left half (full height) switches units (count ⇄ dose); the right half upper area drives the reading UP; the right half lower area drives it DOWN. The number jitters a few percent on its own — that’s intentional, not a fault.
Can't open the Command Center. Swipe up from the meter face (drag a finger upward). Swipe-down does nothing by design.
Gamepad not responding. Command Center → BLUETOOTH REMOTE shows a green dot when connected. A red dot means re-pair in iOS Settings → Bluetooth (the 8Bitdo Micro needs “S”/Switch gamepad mode), then reopen the app.
Alarm won't stop. The alarm latches by design — press ALARM ACK at the bottom of the meter face. If the reading is still over the limit it will re-trip; lower the reading or disable the alarm in Command Center → ALARM THRESHOLDS.
Display reads ERR or OFL. A simulated hardware fault is active. Command Center → SYSTEM INJECTION → CLEAR.
LCD reads µrem when you want mrem. That’s the auto-promote ladder doing its job below 1 mrem/h. Command Center → GLOBAL STANDARDS → DOSE UNIT LOCK → pick mrem to pin it.
Audio stopped after a phone call. It should auto-recover; if not, fully close and reopen the app. Please report it — it indicates the interruption-recovery handler missed an edge case.
Battery icon shows low on a fully charged phone. That’s the simulated meter battery, controllable from Command Center → POWER OVERRIDE — an instructor training control, not your phone’s actual battery.

[ COMPATIBILITY ]

iOS 26.4 or later.
iPhone and iPad (universal app).
Optional: any MFi gamepad with extended profile (the Field Manual uses the 8Bitdo Micro as the reference; other extended gamepads work, though button names default to the 8Bitdo layout).

[ SUBSCRIPTIONS, ACCOUNTS, IN-APP PURCHASES ]

The app has none. It is a one-time purchase and runs fully offline.

[ PRIVACY ]

The app collects nothing and has no network. See the RADIACSIM Lite privacy page.
