IPA Typing Keyboard vs Yr Tuner

Promotional Text (170 char limit — paste verbatim): Type IPA phonetic symbols anywhere on iOS. Long-press dotted letters for variants. Fully offline — no accounts, no data collected. Description (4000 char limit — paste verbatim, including line breaks): IPA Typing Keyboard is an iOS keyboard for typing International Phonetic Alphabet symbols, built for linguistics students, phoneticians, language learners, and anyone who needs IPA symbols in daily work. HOW IT WORKS Install the app, add IPA Typing Keyboard in Settings, then switch to it with the globe key in any app. Tap letters normally for a–z. Long-press any of the dotted letters (a, e, i, o, u, t, s, d, c, n, z) to pick an IPA variant — the same gesture you already know from the built-in iOS é/è popover. DESIGNED FOR PRIVACY • No typed text ever leaves your device. We cannot read what you write. IPA SYMBOL REFERENCE The built-in Reference tab shows every supported symbol with its base letter, name, and a tap-to-copy button — handy for research papers, transcription exercises, or language notes. DEVICE SUPPORT iPhone and iPad, iOS 16 or later. Adaptive SwiftUI layout for every size from iPhone SE to iPad 12.9". NOT INCLUDED (intentionally) No autocorrect, no predictive text, no telemetry, no cloud sync. The keyboard produces what you press — nothing more.

The Lissajous is simple: x - the tone being played y - the nearest tone to what you are playing. It plots x/y and you get the Lissajous. The second kind is more traditionally similar to a strobe tuner. It is more complex under the hood. Both are simple and effective. They are exactly the information you need at a glance without having to think about anything. You can see immediately whether or not you are getting closer or further from being in tune. You don't need to be able to read. You don't need to know how it works. Its as intuitive as it gets, you'll know right away once you use it without ever being told how to use it.
