invi is a good idea, with a lot of promise assuming future updates are still to happen. Unfortunately, with Google’s recently-announced Chat standard rolling out over the next year, it may also be out of date before the app can even get off the ground. There’s a lot to like about invi—overall, we found the experience of using the app positive, and some of the features promised on the app’s FAQ are exciting, including the ability to disable the “Awesome Bar,” RCS support (which would be great for the future of Android), and more customization options. Sadly, without an update in over six months, it’s unclear what the future of invi holds. It’s still a good SMS and MMS option, but its idea of a invi-to-invi future seems bleak at best. Android App
You might know Fitbit from its popular fitness trackers, but the app that powers those devices works well on its own, too. Using your just your smartphone (assuming you meet the minimum hardware requirements), this fitness app can count steps and log activities to help you achieve daily goals. There are also social features, so you can compete against your friends. It's a must-have (really, you must have it) for Fitbit users, but also a smart choice for anyone looking to be more active.
If you use Android, you have a Google Account, and that means you have access to the excellent Google Drive cloud storage service. With Drive, you can easily access synced files across all your devices no matter where you are. With the additional Docs, Sheets, Slides, and Photos apps from Google, Drive is the center of a productivity hub on your Android. Android App
Don't get us wrong, some of us love Instagram. But if you want more control than Instagram affords, try Google-owned Snapseed. This app straddles the line between full-fledged image editor and filter app, all in a sleek and attractive package. Best of all is the amount of control it gives you over how filters and effects are applied to your images. It even lets you make non-destructible edits to raw camera files and make adjustments to exposure and detail levels.
Remember Flickr? The venerable photo-sharing service is an Editors' Choice web service, and the Android app has a lot to recommend it, too. It's more about the art of photography than the meme- and selfie-packed Instagram. Offering a well-designed interface and excellent photo and video editing tools, Flickr is more valuable than ever. Plus, the app connects you to the vibrant community of photographers on the service. Best of all, it can automatically back up photos from your phone. Free users can upload up to 1,000 photos and a $50 per year subscription gets you unlimited online photo storage.

Mood Messenger is one of the youngest apps on our list. It doesn’t have a million and a half features, but that’s one of the nice things about it. Mood Messenger keeps things simple while still offering the key features you’ll want. Mood Messenger users can also send messages to each other without using SMS. The app is completely free with no in-app purchases. Droid App
