With billions of fun and interesting apps available for mobile download, it’s hard to choose the ones that are useful and won’t weigh down our data storage. That’s because, in the digital world, everything looks so colorful and updated that we end up impulsively filling our phones with games and other junk we don’t need. But what do we need?

Our phones are our reminders, our alarms, and even our workspaces. So why not organize it like we would a daily planner? Us women need organization more than anyone—we’re mothers, executives, students, and often multitaskers. It’s hard to keep up with work, family, and ourselves at the same time, isn’t it? Don’t worry, because the following must-have apps for women are here to help.

Period-Tracking Apps

There are countless reasons why menstrual cycles can be late, early or irregular. These include endometriosis, pregnancy, starting birth control, uterine fibroids, among others. But don’t go Google-diagnosing yourself—every woman is different, and a period tracking app can help you monitor your own issues down there.

Interestingly, a recent study suggests that an app-based self-acupressure regimen could help women who suffer from painful menstrual cramps. Sure, all cramps are painful, but to women suffering from dysmenorrhea, they can become nearly unbearable. Knowing whether your periods are normal or not requires a gynecologist visit for a physical examination, but period tracking apps are great assistants.

These apps are helpful if you want to get pregnant or simply want to know the day of your next period or your fertile days. Really, there’s no limit to who can use them. Some of them bring you updates and articles so you can get to know yourself and your days better.

Reminder Apps

Why carry paper planners and pens when we have that and so much more inside our phones? Let’s just accept that our time is ticking by and we have to go through our day without the hassle. In the middle of the bustle, however, we might skip important tasks like taking our oral contraceptives or picking the kids up at school—things we can definitely not forget.

Remembering everything is as simple as taking a few minutes to set up a reminder app, and it will do the rest for you. From creating to-do lists to remembering an appointment, reminder apps are your best bet.

Mental Health Apps

Maybe you’re going through a tough time during intimate relationships, or maybe you just want to improve your quality of life without leaving the house. In any of these cases, what you need is to download a mental health app that’s not only a form of therapy but will help you relax and control your mind better than if you sought no help at all.

Whether you need to learn relaxation techniques or participate in a therapy session at home, there are so many apps to fit your needs. From online marriage counseling to breathing exercises, mental health apps will help you regain your best life.

Phone Tracker Apps

At this point, our phones have become a part of us. We slip them in our pockets but they feel more like a second skin. But we still find a way to lose them and have a mini heart-attack. Fortunately, with a phone tracker app, this won’t happen again. If your device is stolen, an app can help you track the live location. Or, in case you just can’t find it, most apps have the function to make your phone ring from anywhere.

Fitness Apps

Regular exercise isn’t on everyone’s agenda, and that’s fine. But with fitness apps, it’s harder to not stay fit because there’s an app for everyone—beginners, weightlifters, those who want to lose weight, and those who don’t want to pay for a gym membership. No joke, there’s an app for everyone.

The best of all? You can choose apps that are developed by certified personal trainers and offer customized solutions. This way, you know you’ll get the results you need.

Who were we before smartphone apps? We can’t remember where we were, either. All we know is that we’d probably be lost without them. Lucky you, you’re alive at the same time when apps are at their peak, so seize the opportunity to make the most of them.
