SerialSnap
Read full descriptionHide full description
Scan serial codes with your camera. Copy them with one tap. SerialSnap reads the serial codes printed on CD inserts, merchandise and entry tickets, then copies them to your clipboard with a single tap. No more squinting at tiny print and typing character by character. [ Made for people with a lot of codes to enter ] - Typing codes from a CD insert into an entry form - Signing up for an event or lottery that asks for a serial code - Working through a stack of CDs, one code after another - Reading codes printed too small to trust your eyes - Checking a code you entered earlier Here is how typing by hand compares with SerialSnap. | Codes | By hand | SerialSnap | Time saved | | 1 | ~20 sec | ~5 sec | ~15 sec | | 50 | ~16 min | ~4 min | ~12 min | | 100 | ~33 min | ~8 min | ~25 min | | 200 | ~66 min | ~16 min | ~50 min | Serial codes are slow to type and easy to get wrong. Hold the camera over one and SerialSnap recognizes it and copies it for you. [ Main features ] - Scan with the camera High-accuracy OCR reads the serial code as soon as you hold the camera over it. - Adjustable scan frame Codes sit in different places and come in different sizes. Move and resize the scan frame to fit. - One-tap copy The recognized code appears at the bottom of the screen in real time. Tap the shutter and it goes to your clipboard, ready to paste into the entry form. - History saved automatically Every code you scan is kept, newest first, and copying one again takes a single tap. Up to 50 codes are stored, so you can scan a whole stack first and paste afterwards. - Edit by hand Long-press a code in the history to fix a character that was read wrong. - Delete what you no longer need Remove one code with the trash button, or clear the whole history from the button in the top right. - Choose your copy format - As is (example: ABC-123-XYZ) - Hyphens removed (example: ABC123XYZ) Match whatever the entry form expects. [ The three screens ] - Scan The camera opens as soon as you launch the app. Line the scan frame up with the code and tap the white circle at the bottom. The code is copied to the clipboard and saved to your history. - Frame button (top right): move and resize the scan frame. - Ad counter (top left): scans remaining before the next ad (free version only). - History Every code you have scanned so far. Copy or delete from the buttons on each row, or long-press a code to edit it. - Settings - Scan format: with or without hyphens - Copy format: as is, or hyphens removed - Premium: manage your ad-free subscription - Help: a guide to using the app - Legal: privacy policy and terms of use [ Premium ] Every feature in SerialSnap is free to use. The free version shows an ad after a set number of scans. If you would rather work through a long stack without interruptions, Premium hides every ad. It renews monthly, and you can cancel at any time. [ Privacy and security ] - Photos are never saved SerialSnap stores only the text of the serial code. The camera image is discarded right after processing and is never written to your device or to any server. - Your data stays on your iPhone Scanned codes are stored on your device only. Nothing is sent to an external server. - No account needed No sign-up and no login. Download it and start scanning. [ How it works ] 1. Open the app 2. Line the scan frame up with the serial code 3. Tap the white circle at the bottom 4. The code is copied, so paste it into the entry form (you can also copy from the history) Four steps, and the tedious part is over. [ Requirements ] - iOS 17.0 or later - iPhone only (portrait) - Camera access required [ Support, terms of use and privacy policy ] Questions and requests are always welcome.

Karui sorts every notification the moment it arrives. Spam stays silent; friends and one-time codes get through. You can even read unsent messages. And emergencies wake you up, even on silent. Already keep notifications off? You might be missing a friend changing plans or an important delivery. Turn them back on: Karui lets those through and keeps promos from the same apps silent. Already using Focus modes? Karui builds on top of Focus. It judges each message, not just the app it came from, lets your VIPs through from any app, not just Apple’s, and adds what Focus can’t do: • Wake Me: people you choose can ring an alarm in an emergency, even when your iPhone is silenced. It depends on the Karui Shortcut running, so don’t rely on it alone. • Auto Reply tells your VIPs you’re driving, in a meeting, or asleep, and that you’ll reply later. • Deadline reminders: when a message asks for something by a certain day, Karui reminds you the day before. • Several quick messages from one person arrive as one notification. • Notifications translated into your language. • Every app’s notifications in one searchable history. On your Mac too Karui for Mac, free at karui.jp/mac, improves filtering, clears alerts on your iPhone that you’ve already dealt with on your Mac, and keeps your iPhone quiet while you’re using your Mac. Setup Add the Karui Shortcut from a link. It takes about a minute and is all you need to read unsent messages. To filter spam, you also choose a Focus that keeps your other apps quiet. Karui guides you through both. Spam filtering and deadline reminders need Apple Intelligence; unsent messages work without it. Privacy Karui runs on your iPhone with Apple’s on-device model, so your notifications stay on your device. Second Opinion, which setup offers, sends a notification’s text to Apple’s Private Cloud Compute when the on-device model can’t sort it. No server, no account, zero analytics.

Verdict
The clearest difference is in-app purchases: Karui Notifications at none against SerialSnap's 1. Karui Notifications also leads on ads (none vs shown) and update cadence (daily vs fortnightly). SerialSnap's advantage is iOS requirement (17.0 vs 27.0). On price and device support there is nothing between them.
