Sonar Ruler vs 1Extn

Sonar Ruler is a winner in the Best App Ever Awards - "Most innovative use of iPhone hardware" category! The Amazing New Sonar Ruler is an experimental app that uses echoes to measure distances with your iPhone! It uses the same principles that dolphins use to find food! It sends a short pulse from the speaker and measures how long that pulse takes to bounce off of something and return to the phone. It then estimates how far away you are. Use two devices to find the distance between them, without any wifi connection! Use "quiet" mode - with ultrasonic frequencies most people can't hear! Impress your friends with what this unique app can accomplish using only an iphone! GIZMODO.com: "that's a damned neat trick for a phone to be able to do." Features: - Set Units to feet, inches, or meters - Custom saved settings for measuring in different environments If you're a teacher, this app is a great way to teach students the principles of sonar, and how sound propagates through air. Enjoy! Follow us on twitter @LaanLabs NOTE: This is an experimental app, although it can be quite accurate, any measurements taken should be verified before using them.

Make Safari work the way you want. 1Extn - Extensions & Shortcuts brings useful browsing tools, website searches, and personal automation together on iPhone and iPad. Start with ready-made tools, no coding needed and add more control whenever you want. EVERYDAY TOOLS, LESS EFFORT Create QR codes, translate pages, make reading easier, and use Picture in Picture on supported media. Choose the tools that fit the way you browse. SEARCH AND OPEN YOUR WAY Search your favorite websites using short keywords in Safari’s address bar. Set redirects to send matching links to your preferred destination automatically. PUT THE CURRENT PAGE TO WORK Use Actions to copy page details, open saved destinations, pass page information to an Apple Shortcut, or run a saved script. Connect supported workflows to Scriptable, too. MAKE WEBSITES FEEL LIKE YOURS Think of scripts as interchangeable cartridges for 1Extn. Each adds a different webpage tool—hide distractions, change a page’s appearance, or add useful controls. Choose a ready-made script, or paste trusted code into the Script Editor and save it. Then run your saved script in Safari. Add and switch between tools without installing another app. Run scripts when you need them, or enable optional Auto Run for trusted scripts on selected websites. For more control, edit JavaScript, import compatible userscripts, share your scripts, and use variables in supported searches and redirects. DESCRIBE YOUR IDEA Optional AI help lets you describe what you want to create. Describe features use ChatGPT by default, with the option to configure another compatible AI service URL. Review generated results before using them. Apple Intelligence is not required. TAKE A PLAY BREAK Open HTML games made for 1Extn in the app’s game viewer. Download games from the Games Library, or use optional AI help to create your own. HTML games are a separate feature from Safari scripts. YOU STAY IN CONTROL Choose which Safari extensions are enabled and which websites they can access. Auto Run is optional. Import scripts and HTML games only from sources you trust. Some tools depend on the website, media, or permissions available. External AI services and other destinations have their own terms and availability.
