Kigen Tasks is a semi-task management scheduling app designed to help you enjoyably meet deadlines. Kigen (期限) means due/ deadline in Japanese. There is a reason why I wrote "semi". This app is a little too simple to be called a scheduling app. All you need to enter is the title, a quick note, the due date, and the importance of the task. It is also very simple to use. When a task is completed, you just record it as completed. Completed tasks will disappear, but uncompleted tasks will stay on the list until they are completed, regardless of the passing days. Other features include ・Background colours as a due status indicator. When the background colour is green, it is safe! If you have an appointment within 5 days, it will turn yellow, for the next day's task it will turn orange, and on the same day or when an appointment has already passed the due date, it will turn red. ・Punctuality level If you complete a task earlier than the set due date, you will move up a level! On the other hand, if you miss the deadline, you will be downgraded. There is nothing special that happens just because the level is raised, but it is a nice feeling to see the number go up, so I hope you will make use of it to motivate yourself. ・Notification function Notifications are sent one week, five days, three days, two days, the day before, and the day of the deadline! This is why this app is too simple to be called a schedule app, instead, it is an app that was created with the focus on how to help you keep up with your deadlines simply and enjoyably. No more last-minute deadlines!

Block distracting apps. Get teased. Unlock the story. Lock Me! is a character-driven focus timer and app blocker made for anime, visual novel, and character-driven game fans. Ordinary productivity apps can feel cold and sterile. Lock Me! turns focus into a game of temptation and payback, with a cast of cyber girls who make every session personal. Kamia is smug, sweet, and certain you cannot stay away from your favorite apps. Narv is calm, polite, and far more dangerous than she first appears. As they tease, challenge, and keep you company, focused time moves the story forward. Choose the apps, categories, and websites that distract you. Set a focus time, start a session, and let Lock Me! restrict them with Apple’s Screen Time technology. Stay focused long enough and the balance of power begins to shift. Unlock new scenes, learn more about the characters, and turn the tables on the girls who thought they had you figured out. FOCUS THAT UNLOCKS A STORY Your focus sessions move an ongoing character-driven story forward. Progress comes from time spent away from distracting apps—not from simply tapping through dialogue. WATCH MODE Turn your phone into a desk-side focus companion. Keep a character on screen while listening to brown noise, rain, or lo-fi audio. You can also keep the display awake while Watch Mode is active.
