9 Free Apps That Immediately Make Life Easier There is nothing more valuable than time. These apps help you make better use of it.

Apps are everywhere. Research has shown that Americans on average spend nearly three hours per day using mobile apps, and on top of that we tend to put that time into fewer than five apps daily. If you're going to spend so much of your life working on, listening to or playing an app, it better be worth it, right?

Whether they're free, native to your phone, or cost $10 to purchase, you want the app to change your life for the better by doing something no other app can. The good news is that many apps really do go to work for you. From simplifying your routine to clearing your mind or just helping to bring you joy, clear out some storage space and take advantage of what these apps have to offer. All are for iOS and Android phones, unless otherwise noted.

1. Duo

Maybe you've got an iPhone and are looking for an alternative in the video-calling space. Maybe you've got an Android device and Skype doesn't really do it for you. Enter Duo, Google's answer to Apple's ubiquitous app-turned-verb, Facetime. Available on both Android and iOS, with Duo you can make video calls to anyone else with the app and a phone number. It's simple to use and there's an immediate upgrade: the "Knock Knock" feature shows you live video of the caller before you even pick up (insurance against screening a call, perhaps?).

2. Hours Keeper

Being self-employed has its benefits; keeping track of your hours is not one of them. Hours Keeper simplifies the process by organizing the time you spend on multiple clients, letting you sort your hours by pay period and create invoices in seconds with its free PDF template. You can enter your time manually or use the clock-in/clock-out function that acts as a running timer, ultimately helping you stay focused and make the most of your time. There is a paid pro plan.

3. Healthy Living

So, you're eating more organic foods? Excellent. Reading more nutrition labels? Bravo. But what happens when you start asking questions about what's in your everyday products like shampoo or shaving cream? Who do you ask? And are you going to need a translator to understand it?

Enter Healthy Living from EWG (Environmental Working Group), a comprehensive, ratings-based app that explains exactly what ingredients - read: chemicals - are in more than 120,000 food and personal care products. You can search for a product by name, scan a barcode or scroll through the app's own recommendations on everything from the best serums to cereals.

4. Square Cash

One of the newer digital wallet options on the market, the Cash app from Square lets you instantly send money for free to anyone with the app and between different banks via email, text or a "Cashtag," a personalized website (and buzzword) where you can receive money from friends and family. Your account is linked to your debit card, so there's no separate Cash account balance to think about. And bonus: the Cash app has an option for businesses so you can accept payments from clients with no limit to the dollar amount you receive.

Next time, spend about 90 seconds searching Parking Panda for lots or garages near where you're headed. The app is available in more than 40 cities throughout the U.S. and secures discounts up to 70 percent off peak prices. You'll be able to see a map with the cost of a spot at each location, then pay for it in advance and guarantee that it will be there waiting for you when you arrive. Whew.

6. Evernote

If you're constantly searching a combo of a notes app, Pinterest board and bookmark folder for the trove of digital info you create and save, it's time you try out Evernote, which has become the standard among productivity apps and digital notebooks. Evernote collects everything you want to remember in one streamlined platform that's with you wherever you go. Create a note, scan a handwritten note or "clip" a web link and save it within a larger notebook or tag that you can then search for and access across all of your devices.
