This is an English vocabulary learning app using the image generation function by Apple Intelligence. It takes up English words that appear in the English text of the Kyotsu Test and generates and displays images using Apple Intelligence. You can use these images as a reference for memorization. The purposes of this app are - Word memorization - Study how to memorize words - Get used to Apple Intelligence The keywords given to the image generator are selected based on the English sentences of the actual test. I assume that the performance of the app will improve along with the development of Apple Intelligence.

The clearest difference is in-app purchases: Wordrawer at none against ReBrain's 3. ReBrain's advantage is ads (none vs shown) and update cadence (every 10 days vs every 2 months). On price, device support and iOS requirement there is nothing between them.
