This is an app for recording your daily life. Features of week: 1. You don't need to record every day; you can record your thoughts at your own pace. Of course, it is also possible to make multiple notes in a single day. We have prioritized usability so you can record your thoughts as soon as they come to mind. 2. On Sundays, you can look back on the past week. By reviewing the records you have accumulated, you can cherish your discoveries, important events, and even ordinary days. 3. It's not just about recording; we have included various functions to look back on past entries (with more being actively added!). Features include viewing a single random record, seeing your most used emojis, and identifying weeks where you recorded the most, among others. 4. We have paid close attention to ensure it is comfortable to use in dark mode. It switches automatically in sync with your system settings. 5. Your journal text and goals are stored on your device and are not sent to the developer, advertising services or analytics services. To improve the app and display ads, we collect and use information such as device information, app usage, in-app purchases and how the app is functioning. See the Privacy Policy for details. Since you can use the app offline, you don't have to suppress the urge to take notes, whether you are in airplane mode on a flight or using the incredibly slow Wi-Fi on a Shinkansen bullet train. 6. I like designs that are simple and easy to use, yet calm and playful. Please install the app and experience the design for yourself. Before using the application, please be sure to read the following. By installing the app, you are deemed to have agreed to these terms.

Verdict
The clearest difference is in-app purchases: MuudWave at none against week's 2. MuudWave also leads on ads (none vs shown) and update cadence (every 2 days vs every 2 weeks). On price, device support and iOS requirement there is nothing between them.
