Morse-it is an easy-to-use application that lets you translate, interpret, type, learn, convert Morse code, and more. You can run it on your iPhone or iPad and it is compatible with VoiceOver. Note: By getting this app, you'll have access to several useful and fun features related to Morse code (these are the features explained in this description and visible in the screenshots). In addition, you can unlock advanced features in the app if you need them: learning and social features. More information at the end of this description. Type any text and it will be automatically encoded into a full-screen flashing effect of the corresponding Morse code. The flashlight of your device is also used. Your "SOS" messages will be seen quite far away! Some sound will also be played accordingly. In detailed mode, the encoded text will scroll during the decoding process. Tap some Morse code on the screen and the program will translate it into some text. Several input types are supported: Novice, Straight Key, Memory Paddle, Iambic Paddle (A and B), Microphone. Left and right handed modes are supported. Test and improve your skills: are you good enough to be understood? Create Morse code audio files from a given text (or variables). Use these files as you like: listen to them to train your decoding skills or use them as ringtones for your mobile phone. Create beautiful abstract wallpapers for your device (or posters to be printed) by customizing the display of the dashes and dots of the sentence you like. Exclusive feature that allows you to decode in real time the Morse code recorded by the microphone into text (note: the sound must be quite clear/loud and without much noise). Some automatic calibration is performed, allowing adaptation to speed, tone and volume changes. The full Morse alphabet (including prosigns) can also be viewed and the associated Morse code can be played. Tapped and decoded text can be edited and exported to clipboard, in-app email and SMS. A special screen allows textual conversion of Morse code and text. Exchange encrypted messages with your friends. Wikipedia and Visual Mnemonic screens to get information and mnemonics about Morse code. You can also add your own websites for in-app consultation. The whole application is highly configurable (frequency, WPM, tone type, color, Morse code, variables ...) A customizable today view widget can be added to your home screen to display the current date in Morse code. Some custom actions are available in the shortcut app, and some features of the app can be triggered using Siri.

Verdict

The call

The clearest difference is rating: Morse at 4.7 against Audio Spectrum Analyzer's 3.9. Morse also leads on review sentiment (90% vs 54%) and update cadence (every 5 weeks vs every 7 months). Audio Spectrum Analyzer's advantage is in-app purchases (none vs 3) and iOS requirement (6.0 vs 15.0). On ads and device support there is nothing between them.
