An app that lets you display notes right on your lock screen. You'll always see them when you pick up your phone, so you'll never forget what matters. "I wrote it down, but..." You made a note, but never looked at it again — and forgot anyway. Sound familiar? This app is for you. LockScreenNotes solves this by displaying your notes right on your lock screen where you can't miss them. ■ Easy to Use Just tap the note on your lock screen to open the app and jot down what's important. Everything auto-saves, so you can close the app right away without worry. Just focus on writing. ■ Manage Todos Without Opening the App Check off your to-do items right from the lock screen — no need to open the app. Whether it's a shopping list or today's tasks, just check things off as you get them done. ■ Over 100 Designs Choose from over 100 designs, all completely free. Pick one that matches your lock screen wallpaper. You can also customize everything yourself — paper color, text color, line styles, and more. ■ Doodle Away It's not just typing — you can handwrite notes too. Scribble freely like you would on a real sticky note. A quick underline might just help you remember better. ■ Add Images You can paste images from your photo library too. Stick a photo of something you want to buy so you don't get the wrong one, or add a picture of your favorite character to make it cute. ■ Fonts to Match Your Mood Choose from lovely fonts for free — handwritten styles that feel like real notes, or clean and simple ones. With multilingual support, you can even pick fonts for languages you're studying, like English or Korean, and make learning fun. ■ Note History That Shows Your Effort Past notes are saved as history, so you can look back and edit anytime. Use as many pages as you like. The history screen also shows your total character count, number of pages, and how many days you've been using the app. It's proof of your effort to never forget what matters. ■ Privacy Protected No one can see your notes.

Kuku is a 9×9 chart app that unites goal setting with web research. ■ Break your goal into 81 cells From a central theme to 8 elements, and from each element to 8 concrete actions. Splitting a goal across the 9×9 grid turns "what should I look into?" into 81 starting points for research. ■ Follow associations, then search In focus view, tap an element cell to drill into that element's own 9 cells. Tap a leaf cell (the theme or a sub-item) and Kuku opens an in-app web search built from the path you followed (theme → element → item). Step back to return to the level above. Purposeful research, always tied to your goal. ■ Bookmark the pages you find (free) Save any individual page you open in the in-app browser. Kuku records which cell (which path) led you there, so you can revisit everything later from one list on the home screen. ■ Let AI help with the breakdown (two ways, combine freely) - On-device AI (Apple Intelligence): free, offline drafting of all 8 elements × 64 items (supported devices only) - Cloud AI (Kuku Pro): bring your own Claude / Gemini / OpenAI / Qwen API key for high-quality, web-grounded generation Fill everything at once, one block at a time, or get a suggestion for a single cell. AI never overwrites cells you filled in yourself. ■ Privacy first No ads, no tracking, no analytics. Charts stay on your device. API keys live only in your device's keychain and are sent, only when you generate, straight to the AI provider you chose with your own key — never through a developer server. ■ Kuku Pro (one-time, non-consumable purchase) Unlimited charts (free version: 5) / Cloud AI generation / Mind map view (fully expanded, zoomable). Note: Cloud AI requires your own API key and is billed by the provider you choose.

Verdict
The clearest difference is in-app purchases: LockScreenNotes at none against Kuku's 1. Kuku's advantage is update cadence (every 2 days vs weekly). On price, ads, device support and iOS requirement there is nothing between them.
