Every QR code hides a link, and you can't see where it goes until you open it. SeQRCode reads the code first and checks the link for phishing tricks, so you decide before you visit. HOW IT WORKS Point your camera at a QR code or barcode. SeQRCode shows what's inside and rates it Safe, Low, Medium or High risk, with a plain reason for every warning sign. Safe links open with one tap. Flagged links show the security check first, and high-risk links are blocked. 11 CHECKS ON EVERY LINK • Look-alike domains that imitate a well-known site • Look-alike letters swapped in to fool the eye • Link shorteners that hide the real destination • Raw IP addresses and unusual ports • Risky domain endings such as .top • Pressure words such as "verify", "confirm" or "expired" • Fake login pages and risky file downloads • Hidden script and data links • Cryptocurrency addresses, so you double-check before sending money ONE DIAL FOR EVERY CODE • QR: QR codes only, for the fastest lock • BAR: EAN-13, EAN-8, UPC-A, UPC-E, Code 39, Code 93, Code 128, ITF-14 and Codabar • ALL: everything above, plus Aztec, Data Matrix and PDF417 • A torch switch for dim menus, tickets and parking meters YOUR SCAN LOG • Every scan is saved on your phone with its time and risk rating • Filter safe and flagged scans, delete one scan or clear them all • Turn history off at any time in Setup PRIVATE BY DESIGN • Links are checked on your phone. Nothing is sent to a server • No ads, no account, no tracking • Data Not Collected, as shown under App Privacy BUILT LIKE AN INSTRUMENT An LCD readout, a mode dial that clicks into place, key sounds and firm haptics. Turn sounds and vibration off in Setup. SeQRCode looks for common warning signs. It can't promise that a site is safe, so when in doubt, don't open it. Questions or ideas: support@astrochimp.com

Todo

Todo: Tasks & Notes is a clean, distraction-free organizer with two essentials: a classic Tasks list and a simple Notes notebook. No complicated menus, no noisy extras—just the quickest way to get things out of your head and done. Why you’ll like it Minimal by design: a calm interface that stays out of your way. Two focused spaces: manage to-dos in Tasks and write ideas in Notes. Faster capture: add tasks by voice or camera—speak it or snap it, and it becomes a task. All the basics you expect: quick edit, reorder, mark done, and organize. Free forever: 100% free. No subscriptions or paywalls. Key features Tasks: create, check off, and reorder with a tap. Notes: a clean notebook for thoughts, lists, and drafts. Voice to Task: dictate a task when typing isn’t convenient. Photo to Task: take a picture of a whiteboard or paper list—text becomes tasks automatically. Three themes: Classic, Dark, and Black & White to fit your focus. Simple organization: group, rename, and find items fast. Thoughtful details: readable typography, gentle animations, zero clutter. New: Themes that match your focus Choose the look that keeps you in flow: Classic — bright, friendly, familiar. Dark — easier on the eyes (and your battery) for late nights. Black & White — zero color, maximum contrast and calm. Why this matters: the fewer visual distractions, the faster you act. Pick a theme that feels invisible so your brain can stay on the work, not the UI. Make it simple. Keep it done.
 Todo: Tasks & Notes is built for people who want less tapping and more finishing.
