At the end of the day, my father used to come home from work and empty his pockets on the table by the phone. There was often a train ticket, a couple of receipts, and a handful of loose change that got dropped into an old mason jar. We called this the “fun fund” and every so often, we’d dump it out, sort it, and use it to buy ice cream or see a matinee.

Today, most people use a credit or debit card to make purchases. The jingle of spare change is something of a bygone sound.

Fishing nickles out of the washing machine isn’t something I miss…but I must admit, saving up change to made a purchase was fun.

I must not be the only one who feels that way, because there are some great apps out there that give you the digital equivalent to my dad’s mason jar… and they have some really great options for saving that can help you save up a bit at a time towards a goal, or even invest the money so that your “fun fund” grows even faster.

Acorns App for Tiny Investments

One of the best apps for small savings is Acorns. For just $1.00 a month, Acorns will round up the purchases you make on your card and then invest the change. You can choose from several investment options, and then go about your business as usual… all while your spare change invests itself and grows.

The great thing about this app is that it’s just a buck a month, which is even better when you realize that you’re bypassing trade fees and the cut that an advisor would normally take. Plus, the entire process is automated… easier than plunking change into a mason jar, and you have the opportunity to make money in the market at the same time.

Chime Helps You Save When You Spend

If you’re not so interested in investing but would like to save up towards a goal, Chime is a great option. This app allows you to round up and save change, and also gives you the option to put money into a savings account each time you’re paid.

You’re not going to earn interest with this savings plan (well, 0.01% isn’t nothing…but it’s close). However, the app will round up when you make a purchase and automatically deposit it into your digital “fun fund.” You can also transfer up to 10% of each paycheck into the fund automatically, and as an added perk you might be able to access your paycheck a few days early when you use Chime.

The Digital Swear Jar

The less savory cousin to the “fun fund,” the swear jar is where many families collect spare change as a sort of “naughty tax.” Depending on the frequency and intensity of a person’s potty mouth, this jar has the potential to fill up much faster than the other one.

A digital version of the swear jar can be found in the Tip Yourself app. This allows the user to deduct money from your bank account and put it directly into a “tip jar,” and can be used as an incentive (good job, you drank your 8 glasses of water today!) or as a deterrent (you left your gym socks on the floor, put a dollar in the tip jar).

This is a fun way to save as a family, and you can see your progress each time you access the “jar.” A family trip, meal out, or another group treat is a great incentive to work on habits…both good and bad…together, and watching your fund grow is an added incentive to keep one another accountable.

Of course, you can also employ the old mason-jar-on-the-counter trick. But these days, it grows much slower than it used to… and an app is a great way to capture the power of the jar in an easy, tech-savvy, and entertaining way.
