FlashSOS Emergency Flashlight

■ One-Tap SOS Strobe Emergency Signal
Long-press to fire the international standard SOS pattern (3-short / 3-long / 3-short) with synchronised flash and haptics. Strobe adjustable from 1 Hz to 20 Hz. Auto-throttles on low battery and cools down if the torch overheats — never dies when you need it most.
Mis-touch protection (1.0s–3.0s long-press confirmation) prevents pocket fires wasting juice. Dual sync: camera torch + full-screen colour flash doubles your visible distance at night.

■ Morse Code Encoding Engine
Type any text (English, Chinese, digits, or symbols) — FlashSOS auto-encodes it into clean on/off light pulses. 5 playback speeds: 0.5× / 1× / 1.5× / 2× / 4×; base unit duration customisable from 50 ms to 1000 ms. Includes a full printable Morse reference table inside the app. Use it for backcountry distress, covert signals, concert fan light shows, or team codes.

■ Custom Rhythm Editor (Upgrade to Pro — Lifetime Unlock)
Three creative ways to build your own flash pattern:
① BPM Beat Mode — slide from 30 BPM to 300 BPM, every beat fires with millisecond-accurate sync;
② Preset Rhythm Library — 10 built-in scene patterns: Heartbeat / Breathing Light / Lighthouse Beacon / Red-Blue Police Siren @ 1Hz / Concert Cheer @ 120 BPM / SOS International Distress / Strobe Alert @ 8 Hz / 4-4 Rave Kick @ 128 BPM / Flickering Candle / Railway Hand Signal;
③ Manual Tap Recorder — tap the rhythm you want on-screen, we capture the exact ON/OFF timeline locally on your device.

■ Why Choose FlashSOS
• Runs 100% locally on-device. Your typed text, saved phrases, recorded rhythms and history stay inside your iPhone's encrypted sandbox. Nothing uploads to any server, ever — no internet connection required at all.
• Zero privacy footprint. No sign-in, no location requests, no IDFA collection, no background tracking. Only asks for camera (torch LED) permission when you actively tap the flash button, and you can revoke it any time in iOS Settings.
• 12 native languages: Simplified Chinese, Traditional Chinese, English, French, German, Spanish, Italian, Portuguese, Russian, Japanese, Korean, Arabic.
• Transparent privacy policy: full stand-alone page (linked in-app and on App Store) explains exactly what we do and do NOT do with every iOS permission we request.

■ FlashSOS Pro (one-time unlock or monthly plan)
Unlocks all three premium features: Morse Code, Custom Beats and Strobe Warning. The SOS emergency tab stays 100% free forever - life-saving functions are never paywalled.
