A new week has dawned, and with it comes a new list of great things happening on Android. This is the Google Play App Roundup where we tell you what needs to be on your phone or tablet right now. Just click the links to head to Google Play and grab these apps for yourself.

Encrypted communications are available in various apps on Android, but that requires you to get your friends to actually use those apps. Not everyone is going to be keen on switching from their preferred messaging app just because of privacy concerns. Oversec offers an alternative. It uses accessibility and screen overlays to add encrypted communication to almost any app.

After granting access to Oversec to read your screen, you'll get a list of compatible messaging apps. It works with most of the big ones, and you can also enable it to work with many others. You can set which apps you want Oversec to be active in via the settings. I tested Oversec with Hangouts, but it should work the same with most others. There are some tutorial popups that appear as you begin using Oversec, but in general it's a bit confusing at first.

Rather than actually encrypting what the app sends, Oversec just runs encryption and decryption on the local devices. Everything is still sent as plain text. It just happens to be nonsense text. Here's how it works: you enter a message, tap the encryption button floating on top of your messaging app, and Oversec turns the text into junk. On the other end, your friend's copy of Oversec decrypts the junk and displays the original text as an overlay. That's how Oversec works with all these unencrypted apps. It's pretty clever.

Oversec requires a bit of setup before it will work. Specifically, you have to decide on an encryption key. This has to be shared with your friend ahead of time, preferably in person (the app has a QR scanner for importing keys) or via some secure method. The app includes several options for setting up a key. There's a simply password version where you choose the phrase you want to use for encryption. This is the weakest but fastest to set up. You can also have a random key generated in the app, or use a PGP provider.

Oversec isn't the prettiest app with the bright orange overlays and floating buttons all over, but it does what it says it'll do. The concept is a bit confusing at first, but it really can encrypt your communication via any app. The basic functionality is free, but you can buy a full version license for a few bucks. The recommended fee depends on what you're going to do with it. A Student license is a buck and a government license is $109. I'd wager a lot of "students" will buy Oversec.

You've heard of endless runners, but what about endless standers? Chicken Jump is the only one of which I'm aware. The premise is simple—jump, but only at the right time to avoid being smashed by the oncoming vehicles. This game borrows elements from some popular free-to-play titles, but it has its own cool factor as well.

Chicken Jump is an undeniably simple game, but that might be just what you're looking for on a phone. The only control you have to worry about is tapping to jump. The longer you tap, the higher your character jumps. In the default game mode, there are two characters. You can control both of them, or have a friend play with you. Tap the left side of the screen for the left one to jump, and the same over on the right. Everything is done in the same clean voxel style we've become familiar with from games like Crossy Road.

Your characters stand in the foreground, in the middle of the street. That should give you a hint what's going to happen. Indeed, vehicles will drive toward them at an increasingly high rate of speed. Each wave gets a little faster (most of the time) until both of your characters are squished. I like that you can play with two characters, and the timing of the jump varies in some waves. You might have two vehicles to dodge for one character, or the single dodge might just come at a different moment. Chicken Jump throws a few other curve balls at you like tempo changes with the occasional slow wave.

You earn coins from playing the game, which can be used to unlock new characters. Chicken Jump uses "gacha" mechanics for unlocking new characters. You pay 100 coins, and a random character is added to your roster. Some of them just look different, but others include new themes for the game and special abilities. For instance, the mad scientist speeds up time so you skip a few waves every now and then. There are also occasional gifts in the form of a coin drop mini game.

Where I think Chicken Jump gets cool is with the multiplayer modes. You can have up to four players competing on a single device. Everyone taps to jump and the last standing (in the road) wins. There are also a race mode to 15 coins and a weird basketball game that's almost completely unrelated to the rest of Chicken jump.

You can spend a few bucks on extras in Chicken Jump, but there are no timers or lives. Play as much as you want for free.

It's hard to make an open world game work on mobile devices, and even harder to set that works in space. I think Stellar Wanderer does a remarkably good job of it. This isn't a perfect space exploration sim, but it's fun and easy to get into.

You begin the game under attack by space pirates. They blow up your ship, but your mysterious passenger provides you with a new one. Of course, he wants you to do some jobs for him in return. These missions lead to the "main" campaign mode, but there are also a myriad of secondary missions you can take on to earn extra credits.

Your first few missions help you get accustomed to the controls and mission structure in Stellar Wanderer. You can use either a virtual thumbstick or the accelerometer to control your ship. I personally prefer the thumbstick, but your mileage may vary. I like that the controls include a more realistic roll and pitch version, but without yaw control I think the "arcade-style" defaults are better. Your weapon and throttle controls are on the right side of the screen, and they provide all the necessary functions to control your ship without taking up too much space. That said, you'll have to learn a few shortcuts before you are fully up to speed. For example, tapping the speed readout to match your target's speed.

Visually, Stellar Wanderer varies from very good to okay. Most of the objects in the game are viewed from a distance, and they look great. Your own ship has a good amount of detail, and the lighting effects are well done. However, when you do get up close to some objects, you'll notice the textures are a bit fuzzy. The backgrounds could be a little more… substantial. Right now things can sometimes feel too empty. I know, it's space. But still.

When you get into a scrape, the game's default setting is to use aim assist to direct weapons fire when you're close to the target and they are within your targeting reticule. There's a "hardcore" mode where you don't get that. It's more trouble than it's worth—you have to time your shots and aim where the enemy ship is going to be.

The starter ship is okay for the early part of the game, but you can get nicer ones with the in-game currency. They come with more cargo space, more weapon mounts, and faster engines. There are in-app purchases, and Stellar Wanderer is free to download. The free version has a fuel countdown that relies on premium currency, but a $4.99 in-app purchase or higher will remove it completely. There's no ongoing push to make more purchases, so I think the IAPs are fairly innocuous.
