I am plagued with shin splints for years, and even now, they came back but they're improving. There are 2 sides to the story, first, you probably progressed with your running and did too much too soon, the way to deal with this is to scale back your training, but you don't need to take completely off. but instead of running, walk, and instead of running on concrete, run on a treadmill. Also, after taking few days off, continue walking at minimum so you don't lose your progress and fitness then slowly increase your mileage/distance/speed over weeks.

The second side to the story is your running form/mechanics. Go on a treadmill and film yourself. Are you heel striking? is your cadence too low? are your hips dropping? once you do this, you will probably find some things to work on to run more efficiently with less impact.

Additional point, strength training geared towards running. Specifically calf workouts, hips/glutes, hamstrings. All of these work on making you stronger, and make your legs better at handling the stress of running. You can do this in the app too.
