Whether you're working on a novel, a short film, a tabletop RPG campaign, or just need a story for tonight: Plot Spark instantly delivers a character, a conflict, and a setting - random, unexpected, and inspiring. HOW IT WORKS Pick a kit, roll the dice - and get a complete story prompt with character, conflict, setting, and a wild twist. Sounds too simple? That's exactly the point. Prefer instant results over a dice animation? Turn the roll animation off and get straight to the prompt. ELEVEN KITS, EVERY GENRE Plot Spark ships with eleven curated kits - from neon-soaked noir and cosmic comedy to high-seas adventure, Cold War espionage, and Victorian hollow-earth expeditions.

OneDay is an app that focuses only on today's to-do list. What deserves your attention today? OneDay gives every task one of two clear places. What belongs to the present stays in Today. What is undecided or belongs to the future waits in Inbox. Not more management. A clearer today. Key Features • Today See tasks planned for today together with anything overdue. Open OneDay and immediately know what needs your attention now. • Inbox Keep tasks with no Planned Date or with a date in the future. Capture them now and decide when they belong later. • Planned Dates Choose today, tomorrow, or another calendar day. A Planned Date represents when you intend to work on something—not another artificial deadline. • Date Recognition Write a clear date in a title, such as “Submit release notes tomorrow,” and OneDay can recognize its Planned Date when the meaning is unambiguous. An explicitly selected date always takes priority, and recognized date text can be removed from the title automatically. • Automatic Placement Tasks planned for today or earlier appear in Today. Tasks without a date or planned for the future appear in Inbox. There are no complicated projects or lists to maintain. • Priorities Assign High, Medium, Low, or No Priority so the work that matters most naturally rises to the top. • Notes Add context, ideas, or next steps inside a task without forcing everything into its title. • Complete and Restore Complete a task with a tap. Finished tasks are collected into a separate section where they can be reviewed or restored at any time. • Daily Task Reminder Receive one concise summary at a time you choose. OneDay prioritizes the number of overdue tasks; when nothing is overdue, it reports what is still waiting in Inbox. • iCloud Sync Keep tasks consistent across Apple devices running OneDay through your private iCloud database. No separate OneDay account is required. • Optional Notifications Notification permission is requested only when you enable Daily Task Reminder. Every other feature remains available without notifications.

Verdict

The call
