Those things that feel too trivial for a heavy memo app, but too important to risk forgetting. Now, jot them down in Noti. I built Noti for myself because I’m a textbook spontaneous person (Extreme 'P'!) who hates complicated todo apps. You can stack up to 5 lock screen widgets (Notis). Anything goes! Sudden thoughts, brilliant ideas, urgent tasks, or quick appointments—just jot down any simple thing. When you're done, just swipe to delete. Your created Notis stay pinned to your lock screen using Live Activities. Even without unlocking your phone, your tasks are always right in front of your eyes, so you'll never forget an important schedule again. (The Action Button and Shortcuts require an iPhone 15 Pro or newer model.) (Powered by Live Activities and Dynamic Island, you can set up to 5 real-time Notis and deadlines of up to 8 hours.)
