iOS: Exchanging hilarious or embarrassing screenshots is a regular occurrence among a few of my friends, though it often involves receiving multiple images at once, occasionally in the wrong order. Whether you send screenshots of a long text message chain, an emailed receipt you're sharing with a partner, or an entire website you think looks cool, you should download Tailor, a utilitarian app that will automatically stitch screenshots together into a single image.

Mac: If you've ever needed to upload an image or two, or deal with a scanned document, you know about all the headaches that come with conversion, and how finicky sites get with different file types.

In terms of functionality, Apple's generic, preloaded keyboard has certainly improved, but even after adding its own App Store, complete with stickers and apps, it's still a little bland. What I do love about Apple is its support for third-party keyboards. You can ditch the generic offering and download enough keyboards for every conceivable customisation option you want.

Your iPhone has a built in world clock, but it kind of sucks. Zones is not only a better alternative, it also packs in features Apple's option should have.

Mac: Switching apps on macOS with the Command+Tab shortcut is great as it is, but there aren't any built-in tools to customise how the app switcher works. Command-Tab Plus is an app switcher that adds just that.

Windows: RansomFree is a new tool that promises to stop ransomware attacks before they can get busy encrypting all of your data. Instead of watching specific processes or trying to use signatures to identify ransomware, it observes the behaviour of running processes instead, warning you when something's up.

Unless you have a company buying licenses for you, tools like Photoshop, Pro Tools, Maya, or even Windows can be a serious bite out of your wallet. Here are some more affordable options to those normally pricey apps that will help you stop fretting and get more done.

Mac: You have a ton of options for different system monitors on the Mac, but if you're looking for something a little more customisable than the rest, MenuBar Stats 2 is worth a look.

Mac: When it comes to video players on Mac, VLC has long been the best choice. That doesn't mean there can't be competition though. IINA is a video player still in early development that is looking to give VLC a run for its money.

Whether it's a bad date who won't stop texting you or an annoying match on a dating site, Ghostbot can take care of it for automatically.
