OutSpan

Users can choose to expand pages or revert to the original layout, with settings remembered across sessions.
- Fills outer display with web pages
- Expands pages in inner screen split view
- Adjustable blur behind controls
- Persistent layout choices
- No account or tracking
- Built-in setup guide

Use the whole outer display in Safari. When your iPhone Duo is folded, Safari keeps its controls in a strip along the side of the outer display, and web pages stop short of them. OutSpan widens pages into that space, so articles, images, and everyday browsing fill the screen. It does the same on the inner screen when Safari shares it with another app. Choose Wide to expand the page layout, or Off to restore the website's original layout. Your choice is remembered across websites, tabs, reloads, and Safari restarts. • Pages use the full width of the outer display • Works in Split View on the inner screen • Optional blur behind Safari's controls, with adjustable strength • Simple Wide and Off controls in Safari's page menu • One choice that follows you as you browse • No account and no tracking. Everything runs on your iPhone • A built-in guide to turn on the extension SPLIT VIEW Open your iPhone Duo and put Safari beside another app. Safari keeps its controls on the outer edge of its half of the screen, and OutSpan widens pages beneath them. The first time, choose which side Safari's controls are on in the OutSpan menu. Your choice is remembered. When Safari has the inner screen to itself, it shows its controls along the top, and pages already use the full width. FREE TRIAL AND UNLOCK Off is always free. Wide is free for 3 days from the moment you first turn it on. After that, Wide requires Full Unlock, a one-time in-app purchase. There is no subscription. REQUIREMENTS Requires iPhone Duo. On other iPhone models, Safari already uses the full screen width, so OutSpan has nothing to change. Turn on the extension in Settings > Apps > Safari > Extensions, and allow it on the websites you want to widen. Most websites widen cleanly. A few with unusual layouts may not, and Off restores them instantly. Safari's side controls stay on top of the widened page.

Angle Gauge turns the hinge of iPhone Duo into a precision protractor. Set the phone into a corner, against two surfaces or across a joint, and read the angle to a tenth of a degree. MEASURE • Live angle to 0.1°, on the inside display or the outside one • Hold, Auto-Hold when the reading settles, and Zero Here for relative angles • Supplement, bisect and miter angle for every reading • Snap to 1°, 5°, 15° or your own step TARGET • Pick 45°, 90° or any angle with presets and a fine stepper • Haptics build as you get close, then click when you arrive • Tolerance from ±2° down to ±0.25° MATCH • Capture angles into a named library • Find them again later, by feel LEVEL • Bubble level when the phone lies flat, line level on its edge • Two-step calibration cancels the camera bump and the slope of your table • On iPhone Duo, read the hinge relative to true level ON EVERY IPHONE The level works on any iPhone. Measure, Target and Match read the hinge, so they need iPhone Duo with iOS 27.1 or later. BUILT LIKE AN INSTRUMENT • Two-point hinge calibration against fully closed and flat • Degrees, radians or percent open • VoiceOver, Reduce Motion, light and dark • No accounts, no ads, no tracking, and it never goes online

The clearest difference is in-app purchases: Angle Gauge at none against OutSpan's 1. On price, ads, device support and iOS requirement there is nothing between them.
