MorCon is a Morse code learning, conversion, and input app that lets you convert between Japanese or English text and Morse code in both directions. You can easily convert text to Morse code, and Morse code back to text. Morse code can be played not only through speaker audio, but also through screen flashing and flashlight flashing. The app also supports key input, so you can enter signals with a straight key or paddle and convert them into Japanese or English text. A built-in Morse code list helps you check and learn symbols as you practice. The app also includes multiple training modes with selectable ranges, including multiple-choice practice, timed practice, key input practice, and the new Morse Tree Mode. In Morse Tree Mode, you can learn Morse code by growing a visual Morse tree step by step. Each node is unlocked as you practice, helping you understand the structure of Morse code while learning characters naturally. Japanese and English trees are supported, with both key input and listening practice. After mastering a tree, you can unlock Tree Time Attack mode for that specific language and input method. Three built-in sound styles are included by default: sine wave, radio-style tone, and retro game-style tone. Pitch can also be adjusted so you can practice with the sound that works best for you. You can customize the characters used for dots, dashes, and spaces, and adjust playback speed from 5 to 50 WPM. The app also supports exporting Morse playback as audio and video files. In the free version, file export is available with a daily limit. With Premium, file export becomes unlimited.

Verdict
The clearest difference is in-app purchases: ST at none against MorCon's 2. ST also leads on ads (none vs shown) and iOS requirement (12.0 vs 17). MorCon's advantage is update cadence (every 9 months vs every 27 months). On price and device support there is nothing between them.
