I’m a budding PhD student and I’ve been looking to brush up on my orgo- so thank you very much for such a cool product. However, I don’t see a way to create an account. My name is just a string of numbers and letters and I want to personalize the experience a bit more. I don’t believe it’s saving my stats either which is a bummer. I tried contacting that support email within the app but in bounced back saying it was non existent. Would love some help as I am a big fan of gamifying tough science. **Developer response:** Hi there! Appreciate the kind words. Currently your account is tied to your device ID, which is the string of numbers you're seeing. All of your stats are saved locally on your device and store your progress on exercises (e.g. levels) and achievements. For any further assistance, you can reach us at substrate@withexponent.com! ### 5/5 — Amazingly helpful and fun! *2021-02-18, version 1.5.4* If I could waive my magic wand, I’d have this app for every hard subject. The repetition and experience helps me retain, particularly some of the more complicated concepts. ### 5/5 — Great learning tool! *2021-02-17, version 1.5.4* This app is a great learning tool for any organic chemistry student! It lets you easily practice different elements; like identifying chiral centers (which I’m terrible at but now improving!). I can’t wait for this app to hopefully expand to other things like biology! ## Frequently asked questions about Substrate Organic Chemistry ### What is Substrate Organic Chemistry?
