A Day

Tired of your camera roll being a messy drawer of things you don't need? Receipts, parking spots, Wi-Fi passwords, and locker numbers don't belong next to your memories. Meet A Day, the self-clearing visual notepad. A Day is a simple tool built for one purpose: to hold your temporary visual notes, and then get out of the way. Capture a quick "snap" of anything you need to remember right now, but not forever. How it works: - A Clean Slate: Every snap you take disappears automatically after 24 hours. - Just 24: A simple 24-item limit keeps things light and manageable. - Stress-Free Utility: Use it for quick notes, reminders, or anything you'll be done with by tomorrow. Stop cluttering your gallery. Start your day fresh.

Verdict
The clearest difference is in-app purchases: A Day at none against Blue Light Filter's 5. Blue Light Filter's advantage is device support (3 vs 1). On price, update cadence, ads and iOS requirement there is nothing between them.
