Best new Android, iPhone and Windows Phone apps of May 2015

May is traditionally a strong month for apps as the Google I/O event at the end of the month usually brings quite a lot of excitement for software. This time around, Google Photos was the huge announcement, and it's indeed big news: free photo storage in the cloud for images of up to 16-megapixels and videos of up to 1080p, with easy sharing, and super smooth and good-looking companion apps for iPhone and Android.

Google Photos and Pixelmator are two huge new launches this month

A lot of other companies, previously developing great apps for desktop, are also now starting to make their way onto mobile. Pixelmator's debut on iOS this month is great news for photo enthusiasts, as it brings truly rich editing options. Naturally, it has its limitations on that smallish phone screen, but it's great having this kind of possibilities on mobile anyway.

That's hardly all that's new and noteworthy in the world of iPhone, iPad, Android, and Windows Phone apps for May 2015. With no more teasers and no further ado, take a look at our selection of the very best new mobile apps right below.

Google Photos

Google's brand-new and updated Photos app comes to iOS to help you store a lifetime of memories. The app is linked to Google's cloud service, giving you an unlimited storage for photos of a 16 MP resolution or less. Additionally, there are plenty of enhancements to make it more user-friendly – like searching for pictures from events and places, even if you didn't explicitly tag them when you took them.

The MixRadio music streaming application that started as a Nokia exclusive on the Windows Phone platform has now officially made its way onto Android and iOS. With two tiers: a free and premium one, you get to have Spotify-like functionality for a lower price (if you choose premium), and you also get some nice curated playlists to explore.

Twitch

Avid gamers know what Twitch is – it's a service where you can stream yourself playing your favorite games, or, more precisely, watch others stream themselves and weep over how you will never be this good. You can now do the latter activity from the comfort of your mobile device!

Periscope

Twitter's take on Meerkat – a live-streaming app that allows you to show anything you are currently witnessing to the whole world... or at least your followers on Twitter. The app will sync with your blue bird account and inform your subscribers when you are streaming. Of course, you can also just jump in and watch popular streams, comment on them, favorite, and follow.

Office Lens

A Microsoft-made app that helps you preserve schematics, lectures, notes, and anything else by taking a picture of it. The software will let you crop and adjust the image, then convert it into edit-able PDF, Word, of PowerPoint files.

Lenka is a remarkably simple yet powerful, dedicated black & white camera app developed in France by world renowned photographer Kevin Abosch (kevinabosch.com) for professionals & amateurs alike, to create beautiful black & white photographs.

Carbo

A note-taking app that doesn't force you to put away the paper and pencil – quite the contrary. You can use Carbo to take a picture of whatever notes you take and the app's rendering technology will turn them into digital versions of themselves, tucked in your phone's memory. You can also edit them and doodle or mark whatever changes you need to.

Layout for Instagram

Layout for Instagram does pretty much what the name suggests - allows you to lay out images in collages. The app is made by Instagram's own developers, so it should be pretty much the best as far as actual integration goes.

Paint Paper Studio

Paint paper lets you add doodles and text to pictures or blank canvases, filled with various vibrant colors. If you are one who likes to create lots of images to communicate ideas or funnies – you may enjoy this one for a while.
