There is more than 4 billion smart phones in circulation and the chances of you owning one already is extremely high. Most people only use smartphones to communicate and entertain themselves, but owning a smartphone can be profitable too.
There are a variety of ways to use your smartphone to make your life easier, so please use the recommendations best suited for you. We will begin with methods that involve producing assets.
Smartphones can generate assets known as cryptocurrencies. By using the smartphone to process different blockchain ledgers, you will be rewarded with cryptos. The type of crypto you receive will depend on the blockchain you process. This method sometimes may consume a lot of power, and may also cause the device to heat rapidly. Depending on what you mine, and how many cores you would like to use, the power usage and heat level may fluctuate.
Here is a list of apps that allow users to mine cryptocurrencies for Android devices.
Minergate: https://play.google.com/store/apps/details?id=com.minergate.miner
Electroneum: https://play.google.com/store/apps/details?id=com.electroneum.mobile
Pickaxe: https://play.google.com/store/apps/details?id=com.nanobytes.pickaxe
From the list provided, Electroneum mining consumes the least amount of resources and is definitely worth using. Minergate and Pickaxe consumes more power, but allows the user to mine other types of cryptos. The value of cryptocurrencies fluctuates heavily so mining the correct coin may prove to be a great investment for the future.
Next we will talk about apps that allow users to earn gift cards and rewards by performing daily tasks. Most of these apps want the user to watch a video, look at an ad, answer a survey, or provide meta data. Its easy and sometimes fun depending on the app you decide to go with. My recommendations for this category will be listed below:
Slidejoy: https://play.google.com/store/apps/details?id=com.slidejoy
Swagbucks: https://play.google.com/store/apps/details?id=com.prodege.swagbucksmobile
Inbox Dollars: https://play.google.com/store/apps/details?id=com.mentormate.android.inboxdollars
Slidejoy converts your lockscreen into an ad machine. Everytime you swipe your device to unlock, you will receive points from Slidejoy. Accumulate enough points and you can redeem gift cards to Amazon and other websites. Swagbucks is also recommended on this list because its quite enjoyable to do some of their money making features. One such feature would be to simply watch about 30 trailers for upcoming movies. Each time you watch about 5 trailers, the account would be credited with swagbucks or SB. Inbox Dollars is similar to Swagbucks so you can have them both downloaded and switch them in between, as offers do get capped for the day.
The last method falls more under the category of saving money versus generating money. It's good to generate money, but it's just as good to save some money as you try to generate more. Some of these apps may require you to cut a virtual coupon or upload a receipt from a grocery store.
Here's the list:
Ibotta: https://play.google.com/store/apps/details?id=com.ibotta.android
Ebates: https://play.google.com/store/apps/details?id=com.ebates
Receipt Hog: https://play.google.com/store/apps/details?id=com.infoscout.receipthog
Receipt Hog wants to know what people buy, so they can use that information for market research. When you upload your receipts to their app, you are rewarded with points that are redeemable for gift cards. Apps such as Ibotta and Ebates are also quite nice for getting money back from purchases that you otherwise wouldn't have known about. No matter which app you choose to use, or is right for your lifestyle, they all have much upside and very little downside.
