When first mobile phones came along they were something revolutionary and out of this world. They completely changed the way we communicate with each other. The second revolutionary thing in the mobile industry was the transition of mobile phones into smartphones and the introduction of the app stores. Apps drastically changed the way we interact with our mobile devices. Just 20 years ago we could barely make phone calls and send text messages, but now we can convert documents on the go and send them through an online fax service, make payments, capture 4K videos, play augmented reality games, basically the sky is the limit.

We could easily say that nowadays mobile apps have become an indispensable part of our lives. Almost everyone is using them. In case you didn’t know, there are 2.2 million available apps on the App Store and 2.8 million apps on the Play Store which is an enormous number. Some predictions state that in 2020 the app market will be worth around $100 billion and the fact that by now we have downloaded more than 148 billion apps is mindblowing.

Now when we have put all these crazy numbers into your head, you are probably wondering what apps you are missing out on. It is not so difficult to find the most popular apps, but what about all those hidden gems you never heard of?

That is why we created this list of little known, but very useful apps that will expand your mobile horizons.

Skiplagged

There is an endless number of travel apps that can help you book your flights, rent a car, plan your itinerary, find a great hotel and the list goes on. The way Skiplagged is different from others (and totally amazing) is that the app explores a hidden and basically unexplored area of bookings called “Hidden City” flights. Actually, these flights appear to be layovers to other destinations so you can naturally book them less expensively than other flights. It is not an easy search to perform. Simply said, Skiplagged investigates all the possible combinations and gives you the cheapest flights as a result. You can even filter flights by duration, number of layovers, takeoff/landing times and more.

The app provides amazing conversion quality and there are no limits on the file size and the number of files you can convert.

Focos

If you love taking photos with your iPhone camera, then this app is meant for you. It allows you to customize the blur effect and gives you the ability to refocus images. That blur, Bokeh, effect can be adjusted with different shapes (diaphragm settings and adjustable aperture), and even depth filters can be added. Existing Portrait Mode photos can be tweaked, as well. Thus the app doesn’t have the newest customizable lightning features, it won’t disappoint you because it still stands as an excellent addition to your mobile photography game. You should have in mind that it only works on iPhone models with a dual-lens camera.

Clarity Money

If you are one of those people who, at the end of the month, magically find out how little money they have left on their bank accounts and only then start wondering where they have spent it all, then Clarity Money is a perfect app for you. It can become your personal finance app that will help you manage your budget and save money using various methods. You only have to link your credit cards and bank accounts to the app, and then it will examine your spending habits and recognize opportunities to save money like coupons and discounts. The app can also suggest canceling subscriptions you may not be using anymore so you can save even more money. Besides that, users can set a savings goal so the app can periodically take a desired amount of money from your bank account and deposit it into a savings account.

Wakie Community

This one is a little bit weird, but at the same time can be funny, as long as you are into that kind of thing. Wakie is a social app but for phone calls where you can basically ask a random question to a stranger who may or may not know the answer. It is great for socializing when bored or if you want to meet new people or express your feelings. The cool thing is that you can create any topic you want and then you will be matched with someone who would make a good conversation partner. Topics can literally be anything, from light subjects like “I want to speak French with a native speaker” or “Where is the best place to eat ice cream in New York?” to serious ones such as “I am going through a divorce and need an advice”.
