About
HotPaw Productions has been developing unique apps for the iPhone and iPod Touch (and now the iPad) since the Apple iTunes App Store first opened.
Many professional musicians prefer strobe tuners. The HotPaw Productions waterfall strobe tuners are far more accurate than any guitar tuner with just a needle indicator, or even with an LED strobe. With an animated waterfall strobe graphic, even slight differences, between the pitch which the microphone detects, and the ideal pitch frequency, will immediately cause the waveforms to waver and move sideways as they cascade down the strobe window, in real-time.
inTuna Strobe Guitar TunerThe inTuna Strobe Guitar Tuner for iPhone (available from Apple's iTunes App Store) is optimized for 6-string guitar tuning, and includes both a single strobe and multi-strobe mode. It supports 8 popular alternate guitar tunings, as well as a configurable concert A=440Hz frequency.
The inTuna Strobe Guitar Tuner HD is optimized for iPad (and iPad 2). It includes the capability of programming multiple sets of custom per-string intonations.
Sing-inTunaSing-inTuna (available from Apple's iTunes App store). Quickly visualize whether you are singing or playing on key and on pitch in a scrolling graph. This app will draw the note you are singing on a musical grand staff, and color code your pitch accuracy (green line for on pitch, blue for sharp, red for flat).
iChromatic HDThe iChromatic HD Strobe Tuner for iPad allows you to view 12 simultaneous strobe tuners with strobes for all 12 notes of the chromatic scale, easily visible on a piano key graphic, for fast, accurate and noise resistant tuning.
The Blind Talking Tuner uses speech synthesis to speak whether a note the iPhone hears is in tune or not. Useful when you can't see your iPhone display for any reason.
A440The inTuna A440 Strobe Tuner (available from Apple's iTunes App store) is a Free strobe tuner for exactly one note: Concert A = 440 Hz. Try it, and see if you agree that strobe tuners are the fastest and most accurate way to tune a musical instrument.
Music Pitch SpectrumMusic Pitch Spectrum is a real-time 12-th octave audio spectrum viewer for the iPad, which allows one to visualize where a sound, and it's harmonics, fall on the musical pitch scale.
Dance Metronome/BPMDance Metronome/BPM is an extremely (sub-millisecond) accurate metronome as well as a BPM/MPM measuring app calibrated for strict tempo ballroom dancing.
The iAutoharp is an easy and fun to play virtual instrument for your iPhone or iPad. Just tap a chord button and strum to hear the sweet sounds of a 37 string musical instrument.
Music Piano Roll SpectrographMusic Spectrograph is a Universal app (for both iPhone and iPad) now available from the iTunes App Store.
Visualize sounds, almost as they might appear in a piano roll MIDI music editor. Visualize speech and singing. See musical notes (plus all their overtones) graphed to assist with music transcription. The HotPaw Musical Piano Roll Spectrograph creates a scrolling pitch-centered 12th-octave spectrogram in real-time from mic input. You can also pause audio recording to scroll back to review the previous 4 minutes of spectrogram history.Learn and work with CW, a very traditional amateur radio mode of communication.
Morse DecoderThe HotPaw Morse Code Decoder (in the iOS App Store) is a Universal app for both iPhone and iPad which translates Morse Code or audio CW sound into text using DSP signal analysis techniques. Includes a spectrum viewer and an optional narrow band audio filter. Now supports decoding up to 80 WPM. The HotPaw Morse CW Decoder app has been featured in an issue of ARRL Contest Update.
LED Flashlight & Morse Code DecoderLED Morse Decoder and Flash Commicator (available from Apple's iOS App Store) can flash Morse Code using the camera flash on the iPhone 4 and decodes Morse Code flashes, as viewed through a virtual camera viewfinder.
Text2Morse translates text into high quality Morse Code sounds. Configurable WPM and tone frequency.
Morse2TextThe Morse2Text converts Morse code tapping on your iPhone touchscreen into text. You can use this app to input text to your iPhone without looking at the display. Copy the text to use in another app, or email it directly from the app. Both straight key and an iambic keying mode are supported.
MorseTest generates 5 character random letter groups from a configurable letter set and at a configurable WPM to help one learn to hear and receive Morse Code.
MorseKey is a Free app available from the App store. Tap and it will generate an audio tone. Both straight key and an iambic keying mode are supported.

Obsolete PalmOS/PalmPilot apps and info
HotPaw Productions also provides iPhone/iOS app development and DSP consulting services for the most technically challenging problems. HotPaw Productions was founded by Ron Nicholson, who was a member of the original Macintosh, Amiga, and N64 design teams, as well as one of the first PalmOS developers. Enterprise iOS apps co-architected by Mr. Nicholson include Wyse PocketCloud, which has been among the very Top Grossing apps in the Business category of the iTunes App store.
