Once again, it's time to round up our top five favorite apps from the previous month. We rounded up dozens of great new apps in May, but for those who are short on time or internal storage, we've selected five apps that really shined and are worthy of your attention. It's not easy to choose just five apps with so many great candidates each month, but here they are:

CallApp

CallApp, which I had the pleasure of reviewing late last month, is an ingenious application that reminds me that my smartphone can actually function as a phone, and which makes telephony what it should have been all along.

The app enhances your every phone call with tons of information, from the caller's name, to their latest tweet, Facebook update, or shared location. Users can also share things live during the call, set timers or reminders, or see information like location and (where applicable) business hours. CallApp can also give users information about unknown callers, meaning you'll know when you need to answer the phone and when to let it ring.

Best of all, CallApp and all its wonderful functions are totally free from the Play Store. If you want to increase productivity and make every phone call as awesome as possible, hit the widget below.

Safe In Cloud

The self-billed "best password manager for Android Ice Cream Sandwich phones and tablets," Safe In Cloud delivers on its promise, keeping your passwords, card numbers, and other info safe using 256-bit AES encrypted databases storable in your choice of cloud services: Dropbox, Google Drive, or Box.

The first thing you'll notice about Safe In Cloud is its incredibly clean, slick, Ice Creamified interface which makes navigation and overall functionality an absolute pleasure.

Even if you aren't ready to commit to Safe's $1.99 price tag just yet, this is an app to keep an eye on, as the developers provide frequent updates and have promised Windows and Mac OS companion apps will come "later this year."

Open Garden

Open Garden, winner of TechCrunch Disrupt NYC 2012's Most Innovative Startup award, is simply brilliant. To put it simply, Open Garden allows users to let their mobile devices (and the mobile devices of others) "guide each other to the nearest available Internet offramp, regardless of whether it’s a wifi hotspot, a 4G base station or a femtocell."

To do this, the app connects devices like smartphones, laptops, and tablets to a "mesh" network, which the user can then provision to those he or she wants to connect.

In short, Open Garden has huge possibilities, and even in its current beta state, is extremely convenient. Plus, it's free! For more information, check out our coverage of the app here, and download the PC/Mac companion at Open Garden's website.

Shoebox

If you have a sizeable collection of old photographic prints (and no corresponding negatives), and you love looking at photos on your Android device, Shoebox is your dream come true.

Shoebox is an ingenious app that allows users to digitally scan (take a picture of) old photos, and then edit and store them with a surprising amount of organizational functionality. What's really great about this app is that you don't have to set up your device perfectly to properly capture your vintage photos – Shoebox has in-app editing tools to straighten edges and fix any accidental image distortions.

Once you've scanned all your photos, you can easily add back stories, tags, dates, and locations, and share your images to Facebook, Twitter, Google+ and other social services, or keep them in private shoeboxes that only you can see. Hit the widget below to start quickly and easily digitizing and organizing your treasured vintage prints.

jetAudio

JetAudio, which I took a look at last week, is undoubtedly the best audio solution for Android I've seen in a while. Making the jump from PC to Android just under a week ago, the app allows for playback of just about any audio file, from .wav to .mpc, .spx, .wv, .ape, and tons more. The app also offers BBE, BBE ViVA, Wide, Reverb and X-Bass enhancements, and a handy graphic equalizer with over 30 presets.

Besides its various audio enhancements, jetAudio offers a ton of playback options from speed control to crossfading, AGC and more. Additionally, the app's interface is super easy to adapt to. Right now, only the app's basic version is available, but a Plus version should be available soon, offering BBE/ViVA enhancements on top of the ones present in the basic version.

UPDATE: Unfortunately, it looks like JetAudio has completely vanished from the Play Store for reasons that are not immediately clear.

UPDATE 2: After reaching out to the folks at Cowon, we have been told that the app was pulled in order to fix some bugs. "It's going to be uploaded again today or tomorrow."

UPDATE 3: And it's back – jetAudio has returned to the Play Store.

Final Thoughts

If you've been looking for an awesome new app to add to your collection, you've just read about the cream of the crop. Any of these apps would make a great addition to your Android device and are worth checking out. Of course, you can keep an eye out for more roundups, and stay tuned for next month's coverage of June's very finest apps.
