The RF Tools App from HUBER+SUHNER AG is a useful tool, which shows the relation between RF specific values like impedance, wave length, return loss (VSWR) and signal delay including their conversion. On top of this, the RF Assembly Calculator provides an easy comparison of H+S RF cables and assemblies in different configurations and in different environments. It offers a straight access to technical specifications such as insertion loss and power rating. Above all, engineers and students will love this handy and helpful tool. Content Tools Reflection measurement (Return loss - VSWR) Frequency wavelength (Wavelength calculation) Signal delay (Signal delay - Dielectric constant - Velocity in % of speed of light) Impedance dimension (calculation of impedance of coaxial line) dB Calculator (dB Ratio / Watt - dBm) RF Assembly Calculator (comparison of up to three HUBER+SUHNER RF cables) Used formulas are explained in detail by meaningful pictures. Products Provides an overview of HUBER+SUHNER products such as cables, connectors, antennas, lightning protectors and passive components with the help of the product catalogues.

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.

Verdict
The clearest difference is in-app purchases: RF Tools at none against Blinkode's 3. RF Tools also leads on ads (none vs shown). Blinkode's advantage is update cadence (every 2 weeks vs every 14 months) and device support (4 vs 2). On price and iOS requirement there is nothing between them.
