Barcode Scanner is a fast, free barcode reader for iPhone. Simple and easy to use: open the app, point your camera at a product barcode and it reads instantly, with no buttons to press and no photos to take. After a scan, you can look the product up and compare prices with one tap. Scan barcodes one after another, share your whole scan list at once, and read QR codes too. ■ Scan barcodes in seconds The camera starts as soon as you open the app. Aim it at a barcode and it is detected automatically, so you can check a product the moment you pick it up. There is nothing to set up and nothing to type. ■ Look up products and compare prices After scanning a product barcode, search buttons appear for Google, Amazon and other shopping sites. Tap a button to search for the scanned product on that site and compare the prices you find. Check how much an item costs online while you are still standing in the store, without typing the product name by hand. ■ Scan many barcodes in a row Every scanned barcode is saved to your history automatically, so you can move straight on to the next item and keep scanning. Checking a large number of products goes quickly: scan one, then simply point the camera at the next. ■ Share your scan list in one tap Your scan history can be shared as a text list all at once. Scan a stack of items, then send the whole list by mail or chat. This is handy for keeping records of products, sharing a list of items with someone, or saving codes to look at later. ■ Scan codes from images The app also reads barcodes and QR codes from images in your photo library: screenshots, downloaded images and photos sent by email or chat. Select the image and the code is read right away, with no second device needed. ■ Scan history always at hand Every scan is saved automatically. Reopen results anytime, copy them, or share the whole list at once. Your history is stored locally on your device. ■ Light for dark places Turn on the light button to read barcodes in dark places: warehouse shelves, storage boxes, or dim corners of a shop. ■ QR codes supported too The app reads QR codes as well. Open links in Safari or Chrome, copy the content, share it, or search for product information. One app covers both barcodes and QR codes. ■ Main features - Automatic scanning — point the camera at a barcode and it reads on its own - Product search — look up scanned products and compare prices with one tap - Continuous scanning — scan items one after another, saved straight to history - Bulk sharing — send your scan history as one text list - Image scanning — read codes from screenshots and saved photos - Scan history — every result saved on your device - Light button — for barcodes in dark places - QR code reader — open links, copy and share content - Works offline — barcode reading needs no internet connection - No account needed — start scanning right after download ■ One scanner for shopping, work and home Use it as a price checker while shopping, a product lookup tool for reselling and secondhand buying, a quick way to record inventory or belongings, a scanner for books, CDs and DVDs, or a simple QR code reader. One simple app that covers all of these everyday scanning needs. ■ Simple, fast and easy to use The design is clean and there are no complicated settings. Open the app, scan, and you are done. If you want a barcode scanner that just works, this app is for you. ■ Good to know This app is a scanner: it does not create or generate codes. Barcode reading works offline, your scan history is stored locally on your device, and no account is needed at any point. ■ Pricing All features are free to use. The app shows ads, and there are no subscriptions, no in-app purchases and no paid plans. ■ Download Barcode Scanner today Scan, look up and share barcodes with one simple app. Download now and read your first barcode just seconds after opening the app!

Walk away with peace of mind. Did I Lock? lets you verify the door, the stove, the car, your meds, and more in one tap — so you never have to turn back or wonder again. If you've ever driven home to check a lock, lain awake replaying your night routine, or torn the house apart looking for your keys, this app was built for you. Capture photo proof, log it, and let the worry go. KEY FEATURES Verify anything: locks (doors, gates, garage, windows, car) and appliances (stove, gas, iron, oven, heater, AC), with insistent alarms for the dangerous ones. Photo proof and voice notes: snap a picture or record a quick note as real evidence you can look back on anytime. Smart reminders: time-based, recurring, or evening "sweep" reminders, plus triggers that fire right after you unlock your phone or open the app. Three reminder styles: a standard notification, a looping full-screen alarm, or your own voice memo — mark done, taken, skipped, or snoozed straight from the notification. Item memory: remember where you put your keys, wallet, or passport with a last-seen photo and room or place. Medicine tracking: log doses as taken, skipped, or snoozed and watch your adherence over time. Plants and routines: water and fertilize on custom cadences, and build reusable checklists for leaving home, travel, or bedtime. Insights that encourage you: forgiving streaks, an 84-day activity heatmap, and gentle pattern observations — never guilt. Ease my mind: a calm screen that shows your recently verified items as proof, plus a guided breathing exercise. Today dashboard: pending verifications, what's done, upcoming reminders, and recently saved items at a glance. Stay organized: categories, favorites, color tags, rooms, and fast search by name, note, or place. Your data stays yours: everything is stored on-device with biometric or passcode lock, a 7-day recovery trash, and local CSV/JSON export — no cloud sync, no accounts. Stop second-guessing yourself. Verify it once, see the proof, and get on with your day. Developed by Fexo. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
