Ratings and reviews

You're forced to make an account, seems unnecessary, but ok. This process is then made as difficult as possible by having the country of practice list in a completely random order. It's not sorted alphabetically, not even sorted by continent. Same with specialties, there's no order to it. App works fine, has an incredible amount of calculators. Specialty specific lists seems irrelevant, they're very extensive lists, but then YEARS isn't in EM for example.

Any app requiring me to hand over my information to create an account before it shows me what it offers in return, gets an automatic one-star review and deleted from my phone.

UPDATE 10/26/24: the app opens up quickly now! Calculators are also accessed easily. Good job on fixing the bugs! 🙌 ----- [OLD REVIEW] The beta version takes a really long time to open up. One time I waited 10mins and it didn't even work then. I reinstalled the app, and while it opens up better now, it still takes around 30secs or so, not instantly
