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.

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.

AppSpark is a fast, focused idea catcher for indie makers — app ideas, feature ideas, book and Etsy ideas, the lot. Get it out of your head in seconds, then work out what's actually worth building. CATCH IT ANYWHERE - Fire off an idea with Siri, a Lock Screen or Home Screen widget, or straight from your Apple Watch — you don't even have to open the app. - Tag what it is: new app, app feature, Mac port, Watch companion, book, Book → App, Book → Etsy, market opportunity, or bug fix. TRIAGE THE WINNERS - Everything lands in one inbox. Sort the keepers from the noise and move ideas along a simple pipeline: Spark → Queued → Green-lit. - Add research and notes as an idea firms up. - AppSpark resurfaces ideas that are going stale, so the good ones don't quietly die at the bottom of a list. READY TO BUILD - Green-light an idea and it's ready to flow straight into AppBlueprint to plan and build. AppSpark works perfectly on its own, too — use only the parts you want.
