These days, whether you need an app for sewing, organization, health tracking, gaming or just about anything else, chances are pretty good that you’ll find it.

With hundreds of thousands of apps for mobile devices currently available and hundreds more going live each day, there is a lot to choose from to add to your personal collection of apps.

Here are four apps that are useful, fun, purposeful, unique and already wildly popular for 2015 that you might consider adding to your download queue:

ShuvAppetizer Mobile

Appetizer Mobile, a mobile application development, consulting and marketing company located in New York, NY, designed Shuv – a free communication app. The app lets users choose ringtones that will be heard by the person they are calling or the person to which they are sending a photo. The app also features free unlimited world-wide calling and messaging capability to anyone who also has the Shuv app. This saves callers and receivers money and minutes on their calling plans.

What is really unique about Shuv is the Ring Forward™ technology that Appetizer Mobile has integrated into it. It’s a new technology responsible for the ability for users to select from over 15,000 songs and sounds as a ring forward ringtone. Shuv is available for both iOS and Android devices.

PippitY Media Labs

Y Media Labs is a digital agency that builds mobile apps, responsive websites and more for its clients. YML is behind the popular app Pippit. Pippit is an app that people use to bookmark items and activities they enjoy while they follow chosen friends, brands and bloggers they prefer. The entire experience is unified as they create and share “pips”.

Pippit is a popular app for sharing photos and videos, lending inspiration along with entertainment and plenty of conversation to users. Pippit has received rave reviews and has been ranked as #2 in the lifestyle category on Apple’s App Store. Currently the app is available only for iOS users.

Nom Nom PaleoY Media Labs

Another app to watch in 2015 is the Nom Nom Paleo app for iOS, also from Y Media Labs. This app is the result of author Michelle Tam, whose popular blog and cookbook provide its basis. Tam wanted to have an app created that complements her cookbook and blog – Nom Nom Paleo offers 128 recipes that are based on the Paleo Diet in an app that is immersive and effective.

Nom Nom Paleo is a best-selling app that has been recognized by Saveur Magazine, was a Top 3 finalist for Best Cooking App in the 5th Annual Best App Ever Awards, and is the winner of the 2014 People’s Choice Webby Award. The app is available for iOS only.

VOXXAppetizer Mobile

Another app by Appetizer Mobile, the VOXX app, is one that is designed to protect chat and cellular call communications from illegal tracing, recording and monitoring. The app is brought to users via VOXX International, a company focused on privacy and counter-surveillance, along with Appetizer Mobile.

VOXX International brings users this app in the midst over growing public concern with privacy rights, the increase in spy software and recent talk of the ease with which outside parties can listen to private phone calls.

While the app currently focuses on the privacy of only cellular calls and chats, VOXX and Appetizer Mobile plan on extending the VOXX service to other areas in the near future. The aim will ultimately be to secure people’s right to privacy regardless of what type of communication form they use. Open and standard encryption algorithms and protocols along with military-grade coding are used for the app thanks to a partnership between VOXX International and top security labs. The app is available for both iOS and Android.

2015 will likely be a banner year for new apps that seem to make the impossible possible across an enormous variety of industries, platforms and niches, so in addition to the four apps mentioned above, be sure to keep your eyes peeled for other apps that will knock your socks off this year!
