••• Requires xScope 4 available from the Mac App Store ••• xScope Mirror lets designers and developers effortlessly preview any Mac desktop image directly on your iOS device or Apple Watch. Unlike other preview apps, xScope Mirror doesn’t have any desktop chrome to get in your way while you work or require you to save files again and again. Simply launch xScope Mirror on iOS and then xScope on a Mac to begin. Confirm the connection on iOS and then drop an image file onto the Dock icon for xScope. A remote connection to Photoshop is also supported: this lets you preview changes in your PSD while you edit. The Mirror can also display any window on your Mac or images copied to the clipboard. Finally, any image that's displayed on the iOS device can be transferred to the Apple Watch by tapping on its screen. Layouts that are taller than the watch's screen are scrollable. Any file that matches the icon sizes for the Apple Watch will be presented with circular mask against a black background, allowing quick asset previews. Features include: • Remote Viewing – Easily view the contents of any Mac desktop window on your iOS device or Apple Watch • Apple Watch – Includes a watch extension that makes previewing on your wrist a snap! • Pin & Lock – Move the Mac window anywhere (even under other windows) & it always stays in focus on iOS • Chromeless UI – No overlaid chrome to get in the way while you work • Retina Scaling - Preview mirrored content 3:1, 2:1, 1:1, 1:2 or 1:3, great for testing on Retina devices • Compatibility – Runs on all devices using iOS 5 or later • Security – Toggle user authentication requests on/off via Preferences in the xScope desktop app • Multi-client – Multiple iOS devices can connect and view the same Mac window – Great for demos or meetings • Sharing – Copy the current image to the iOS clipboard or save it in your Photos • Nudge – Nudge the selected window one pixel at a time (useful on Retina displays)

About

CatGrab

Features
Read full description

CatGrab is a to-do app with a cat, a fish, and a very simple idea: every day, the cat makes a move. Each CatGrab is one action you take today. Each fish is what you are after — a goal you want to land, or a partner you want to chase it with. Add a task, hook it to a fish, and watch the day add up. FIVE STATUSES, NOT JUST A CHECKBOX Real work is rarely just done or not done. Every CatGrab carries one of five states: To Do, Doing, Done, Blocked, and Cancelled. Tap the status circle, or drag the status pill in the editor, and you always know what is moving and what is stuck. A LIST THAT SORTS ITSELF Todo, Upcoming, and Done. Today's items come first, overdue ones sit right behind with the most recent on top, and anything without a time waits quietly at the end. Due today is marked yellow, overdue is marked red. No dragging, no manual ordering. FISH: YOUR GOALS AND YOUR PEOPLE A fish can be the big thing you are working toward, or someone you are working with. Import from Contacts in one step, or create a fish by hand with an avatar and a note. Star the ones that matter and they always come first — in search, and in the picker when you attach a fish to a CatGrab. Open any fish to see everything you have done for it. A CALENDAR THAT SHOWS THE CATCH Zoom from year to month to day. Every day is painted with the status of what happened on it: a single status draws its own icon, several draw a split. Look back at a week, a month, or a whole year and see exactly how much you actually caught. REMINDERS THAT ARRIVE IN TIME Reminders are set as lead time, not a fixed hour — thirty minutes before, two hours before, whatever suits you. The app icon badge counts what is still open and due, so a glance at your Home Screen is enough. TIME IS OPTIONAL Not every task belongs on a clock. Turn the time off and a CatGrab simply lives in your list until you get to it. BUILT FOR IPHONE AND IPAD Everything syncs through your own iCloud account, so your iPhone and iPad stay in step. There is no CatGrab account to create, and your tasks are never uploaded to our servers. Available in English, German, Spanish, French, Italian, Japanese, Korean, Dutch, Simplified Chinese, and Traditional Chinese. FREE, WITH ONE OPTIONAL PURCHASE CatGrab is free to use and supported by ads. An in-app purchase removes them permanently. Every feature described above is included either way — nothing is locked behind the purchase. Make a move. Catch the fish.

Verdict

The call

The clearest difference is in-app purchases: xScope Mirror at none against CatGrab's 1. xScope Mirror also leads on ads (none vs shown). CatGrab's advantage is update cadence (every 8 days vs every 7 months). On price, device support and iOS requirement there is nothing between them.
