This is a very simple touchscreen-based Morse Code straight key. Practice sending Morse Code on your iPhone or iPod Touch. Touch the display screen and the device will sound out a tone. The duration of the tone is controlled by how long you touch the device screen. Send Dots using quick touches, and Dashes by touches held down 3 times longer. The tone frequency is adjustable from 300 Hz to 1200 Hz in the Settings. The volume can be adjusted to a lower level as well. There is also an iambic keyer (mode A) with adjustable dot speed available. A Morse Code tutorial is not included. You can find one on Wikipedia or on the ARRL website. Also see MorseTest, in the iPhone App Store, another educational Morse Code application by HotPaw Productions. ## Key features - Touchscreen Morse code key - Adjustable tone frequency - Adjustable volume - Iambic keyer (mode A) - Adjustable dot speed ## Recent user reviews (10 of 68) All indexed reviews: https://appshunter.io/ios/app/morsekey/id312260358/reviews.md ### 5/5 — VK3SSS Australia *2026-04-05* Great little app. Less than 500kb! Thanks 😊 ### 5/5 — Very good *2025-11-30, version 1.3.5* It is a very good app no ads i highly recommend it if you wanna learn morse code. ### 5/5 — I love this! Could you make a watch version? *2025-08-08* I absolutely love this because it is free and does exactly what I was looking for. But better. I hope to see this on watches because I think that would do very well and I have an arch of my own. 10/10! ### 5/5 — Awesome *2025-06-08* It does exactly what it’s supposed to do ### 5/5 — よさげ *2024-08-22* ただのモールスキーで何も無駄がない ### 5/5 — Great practice key with very little lag *2024-06-25* I’ve found several morse apps where there is a lag. I’ll be using this app for a long time. ### 2/5 — Non è completa *2023-07-11, version 1.3.5* Il tasto va bene, è sufficientemente largo per non colpire fuori, le regolazioni sono buone, manca uno schermo dove appare quanto scritto. ### 1/5 — I am the same guy *2023-06-02* Curse this app ### 5/5 — Seems to Work on iPhone 13 *2022-10-31, version 1.3.5* I am going to make another attempt to learn Morse code. Seeing some people were having trouble with the app, I thought I should include specifics about the combination of hardware & software. This is an iPhone 13 Pro Max running iOS 15.7 (I will likely upgrade to iOS 16 in a month or so.) ### 5/5 — Works perfectly *2022-08-22* Use this app ## Frequently asked questions about MorseKey ### What does MorseKey do?
