Mirrored Body vs Thirty or Nothing

This app is for experiencing “null²n (Null Null Nexus)” and “null⁴ (Tetra Null).” First, tell your profile to your Mirrored Body, your digital double. Then, scan the QR code at the venue. Children under 13 and users living outside Japan should use Mirrored Body Lite, which does not include the AI conversation feature.

Thirty or Nothing is a diary app that allows you to write only during a 30-minute window each day, starting from the time you set. With the motto “Carry the joy of writing through your pen,” this app is for anyone who has quit journaling again and again—and wants to finally make it stick. It was born from the developer’s own struggle: because you can write anytime, you end up writing “later”… and the habit quietly fades away. By intentionally adding a constraint, Thirty or Nothing aims to spark the urge to write and help you keep going. Getting started is easy, and the features are intentionally simple: ■Set your “Daily Start Time” on first launch Starting from your chosen time, you can write your diary for 30 minutes every day. ■Reminder notifications to prevent forgetting Sends a banner notification at your set time. ■Photo attachments You can attach up to 5 photos per entry. ■Tags Register tags with # to organize and group your memories. ■Full-text search Search your diary entries by keyword. ■Font & text size customization You can change the font and text size.
