Knoq

See where a QR code really goes before anything opens. Knoq follows every short link and redirect and shows you the real address, with no ads over the camera and no weekly plan. Scan the code on a menu, a parking meter or a flyer and the result card shows the destination first: each hop the link took, struck through as the next one lands, and the domain it finally reaches in large type. Nothing opens until you tap Open. IN-APP PURCHASE: Knoq is free to download, and the app is unlocked with Knoq Pro, a separate in-app purchase offered as a monthly or yearly auto-renewing subscription, or a one-time lifetime purchase. There is no free trial that turns into a charge: the price, the plan length and the renewal terms are shown on the purchase screen before you confirm. Subscriptions renew until you cancel them in your App Store account settings, and earlier purchases can be restored from the purchase screen. WHERE IT REALLY GOES • The full redirect chain of a short link, followed from your phone before the page opens • The address in plain words: a lookalike of a known brand is named, along with the real site • It tells you what it found, never that a link is safe, so you decide with the facts SCAN ANYTHING • Opens straight to the camera, with a torch and zoom • Reads codes from photos and screenshots • Batch mode for a stack of codes • Wi-Fi codes join in one tap; contact codes open the new-contact card MAKE YOUR OWN • Link, Wi-Fi, contact, text, email and message codes • Your colours, with a warning when a camera would struggle to read them • Share as a PNG, or show it full screen at full brightness YOUR HISTORY • Every scan kept with where it went: search, favourites and tags • Trash keeps deleted scans for 30 days • Syncs through your own iCloud, and exports to CSV No account, no sign-in and no ads. Your scans stay on your device and in your iCloud. LEGAL Privacy Policy: https://beratmehmetoglu.com/privacy/ Terms of Use: https://beratmehmetoglu.com/terms/

Verdict
The clearest difference is ads: Knoq at none against Bubble Level & Compass's shown. Knoq also leads on update cadence (every 2 weeks vs every 11 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.
