Blinkode

Blinkode sends and reads Morse code in TWO alphabets — international A–Z and Thai. Everything runs on your device. No internet, no account. THAI MORSE CODE Thailand has had its own Morse standard since 1 November 1912, created so telegraph operators could send Thai without transliterating it first. It is still used by Thai amateur-radio operators today. A Morse app that only knows A–Z simply cannot carry a Thai sentence. • Type in Thai and Blinkode encodes it — no mode switch to find, it reads what you typed • Mixed Thai and English in one message encodes correctly end to end • Full Thai reference table with the source of the standard shown on screen • Because the standard gives one code to letters that sound alike, Blinkode warns you which letters will arrive as another — no silent surprises • Characters outside the standard (Thai numerals) are flagged, not dropped in silence APPLE WATCH Morse was built to be received by feel. Blinkode plays decoded messages as dot-and-dash haptics on your wrist, so you can read a signal without looking at a screen, without sound, and without light. • Replay any message your iPhone decoded, as timed taps • Trigger the iPhone flashlight from your wrist • Practice mode: feel a letter, guess it — the way operators actually learn WIDGETS AND THE ACTION BUTTON The moment you actually need Morse is the moment you do not want to unlock, find an app and type. • SOS widget on the Home Screen or Lock Screen — one tap opens straight into sending, no menus • Put the same SOS in Control Center, or on the Action button of iPhone 15 Pro and later • SOS sent this way never counts against the free daily limit • "Today's code" widget teaches you one Morse letter a day — in Thai or A-Z, matching the alphabet you use in the app • All widgets are free, no Pro needed 10 LOOKS, ONE TRANSMITTER A full transmitter panel: display, rocker switches, speed dial and transmit key. • 6 classic themes, from bold Brutal to neon Future • 4 Real Device themes styled after hardware of their era: Deck 80, Telegraph 40, Ham 70 and Handheld 95 SEND • Flashlight, on-screen flash, sound or vibration • 5 to 30 WPM • loop mode • hold-to-send SOS DECODE • Point the camera at a flashing light and read it back live • Auto speed detection • The same signal can be Thai or English — switch how it is read with one tap, no need to capture again • Read blinks from a video clip you already filmed (Pro) FREE • 5 signals a day • unlimited decoding • full reference tables • 4 themes BLINKODE PRO • Remove all ads • unlimited signals • video decoding • unlimited history • all 10 themes Weekly, yearly or one-time lifetime — yearly saves over 90% compared with weekly. PRIVATE BY DESIGN Works fully offline. Camera frames and video clips are never saved or uploaded. Blinkode Pro is offered as an auto-renewable subscription (weekly or yearly) or a one-time lifetime purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period; manage or cancel anytime in your Apple ID settings.
