Getting ready to apply to med school is hard enough. Keeping track of all the things you need to do, what progress you have made, and importantly how it ties together is super important--so we created the Premed App, designed to help you do just that. One big difference between this app and others is that we focus on narrative, something most apps and trackers do not. From our experience working at some of the top Medical Schools in the world (including Harvard, Stanford, and others) we have come to see that the most successful applicants are those that are intentional early on about what they do and why they do it. Our app helps make that thought process easy. If you have suggestions for features or changes, we would love to hear from you!
