Complete camper and RV heating management, reimagined for iOS — now with Apple Watch, CarPlay, a Home Screen widget and Live Activity. External hardware required: a self-hosted MQTT/BLE gateway device, configured and provided by the user (not included, not manufactured or sold by MF-Lab). CONTROL FROM YOUR IPHONE Monitor temperatures, adjust heating modes, and manage hot water settings directly from your iPhone. Choose Bluetooth for local, offline control or MQTT for remote access from anywhere. • Dual connectivity: Bluetooth (BLE) and MQTT • Real-time temperature monitoring • Battery voltage tracking with visual indicators • Detailed error code explanations • Hot water control (OFF/ECO/HIGH/BOOST) • Energy mix selection (Gas/Electric/Mix) • Background operation support ON YOUR WRIST A dedicated Apple Watch app shows live status at a glance — room and water temperature, battery, connection state — and lets you adjust the room temperature or switch heating modes without reaching for your phone. Get an alert right on your wrist the moment something needs attention. IN THE CAR Check your camper's status from the CarPlay screen while you drive: connection status, temperature, battery, and heating mode, laid out for a quick glance with minimal distraction. ON YOUR HOME SCREEN AND LOCK SCREEN Add the Tru-Control widget to see your heater's last known status without opening the app, or start a Live Activity from Settings to keep the status on your Lock Screen and in the Dynamic Island while the app is running. ONE-TIME PURCHASE Unlock Tru-Control once, with no subscription and no recurring charges. Purchases can be restored at any time from Settings, and offer codes can be redeemed in the app. Tru-Control is an independent, unofficial application and is not affiliated with, endorsed by, or sponsored by any heating system manufacturer.

Cue Killer is show control for performers who run their own AV. Build one ordered cue list, press GO, and let the next slide, sound, video, camera cut, overlay, blackout, QR moment, or transition land exactly on your beat. Made for magicians, mentalists, speakers, musicians, comedians, event hosts, worship teams, buskers, and anyone who has to perform and run the booth at the same time. WHAT YOU CAN CUE - Slides, PDFs, Keynote/PowerPoint exports, images, video, audio, live camera, text, frames, lower thirds, QR codes, audience polls, waits, groups, mic/listen mode, blackout, and stop-audio cues. - Audio cues include fades, crossfades, looping, trim, level control, and a dedicated kill-audio action. - Visual cues can use cinematic crossfades or dip-to-black transitions, plus branded overlays and big live text. RUN IT HANDS-FREE - Map GO, BACK, LIVE, blackout, deck navigation, and audio actions to Flic buttons, Bluetooth clickers, game controllers, MIDI, OSC, or the built-in web remote. - Add spoken trigger phrases so a line in your script can fire any cue. - Use the camera to recognize a prop and fire the matching cue while your hands stay in the routine. BUILT FOR THE BIG SCREEN - Send clean audience output over HDMI or AirPlay while your iPhone or iPad stays on the operator console. - Use live camera cues with zoom, picture-in-picture/split layouts, peer cameras, browser cameras, and overlays. - Fire audience interaction cues: the crowd scans a QR code or enters a short code at cue-killer.com, then votes in live polls, number guesses, or word clouds. BUILD FASTER - Import media once and reuse it across shows. - Import Go Button, StageCue, and CSV show files. - Use Killian, the in-app assistant, for setup help and for generating show ideas, cue drafts, images, sound effects, music beds, and voiceovers when you connect your own AI keys. CONFIDENCE UNDER PRESSURE Cue Killer is designed around the live moment: what is on air, what is standing by, what GO will fire next, and how to panic-silence everything fast. It is approachable enough for a solo performer, but serious enough for a real stage.
