IRSignalTester vs Telepathy

IR Signal Tester is a simple utility for testing infrared (IR) signals using your phone’s camera. Check if a remote control is working, compare signal strength between remotes, or detect infrared light from IR LEDs — all in real time. No ads, no fear-based claims, just a practical tool that works. What the app does Most infrared remotes and IR LEDs emit light that phone cameras can detect — even though your eyes can’t. IR Signal Tester makes this visible and measurable. Use it to: Test TV, AC, and media remotes Check if a remote is weak or failing Compare signal strength between remotes Detect infrared light sources and IR LEDs Features Live IR Detection Real-time camera view Clear “IR detected” indicator Signal strength meter (weak → strong) Remote Control Test Guided 3-second test Signal health results: Good, Weak, Intermittent, or No Signal Helpful explanations for each result Compare Remotes (Pro) Test two remotes side by side Compare signal strength and stability Quickly see which remote performs better Clean & Private Works completely offline No accounts, no tracking Camera access only, used solely for IR detection Who it’s for Anyone troubleshooting a TV or AC remote Technicians and installers DIYers and electronics hobbyists Anyone who wants a simple way to check infrared signals Important note IR Signal Tester detects infrared light signals, not hidden cameras or surveillance devices. Results depend on camera hardware and lighting conditions.

Telepathy moves small pieces of text between two nearby devices using sound you can't hear. Type a password on one phone, press Send, and it appears on the other — no Wi-Fi, no Bluetooth, no pairing, no account. The data travels through the air as near-ultrasonic tones (16.4–18.1 kHz) and never touches a network. Perfect for the moments that are always harder than they should be: • Give a guest your Wi-Fi password without spelling it out • Move a password or one-time code to a colleague's phone • Hand off a link, an address, or a note to any nearby device • Transfer between devices on different Apple IDs — nothing to set up HOW IT WORKS 1. On the receiving device, switch Listen on 2. Type or paste on the sending device and press Send 3. A short tone sequence plays — the receiver decodes it live and shows it with one-tap Copy Every transfer is integrity-checked (CRC-32), and a live spectrum view shows all 19 acoustic channels working in real time. Long Range mode trades speed for extra reliability past 2 m. PRIVATE BY DESIGN • No internet, no servers, no cloud — the sound in the room is the entire network • Works completely offline, even in airplane mode • No account, no analytics, no tracking. The microphone is used only to decode tones while Listen is on; nothing is recorded or transmitted anywhere TELEPATHY PREMIUM Telepathy requires a Premium subscription, with a 7-day free trial for new subscribers — try everything free for a week. Payment is charged to your Apple ID account; the subscription auto-renews unless cancelled at least 24 hours before the current period ends. Manage or cancel anytime in Settings. Both devices need Telepathy running. Best results within arm's reach in a quiet room.
