I think it would’ve been nicer if the app had a feature to write the amino acids, but even without it, it deserves a 5 star rating. ### 5/5 — Love *2025-12-16, version 1.6* I wish i found it sooner it’s so helpful! It even helped me memorize them all in one day. i love that you can choose how you want the questions asked and what answers to choose from. I like that for the answers it doesn’t give you options that are obviously not correct, it adds some that are similar to trick you a little and make you think about it more carefully. i’m obsessed!! ### 5/5 — The Best! *2025-11-15, version 1.6* This App is perfect for memorizing the amino acids! I wish I found this sooner. Cannot recommend it enough for those trying to memorize. It allows for easy spaced repetition over periods of months and is actually fun to do! ### 4/5 — Grievance *2025-11-06, version 1.6* Lovely tool, but is lacking one of the most important things which is the pKa of the side chains. This would bring this app to the next level, many of my friends who also have it agree! ### 5/5 — Great for memorization *2025-11-04, version 1.6* Helps me remember the structures, names, three letter abbreviations, and single letter abbreviations. I like that it keeps track of your score on specific residues so that I know what I need to buckle down on specifically. ### 5/5 — 너무 좋고 유익합니다! *2025-10-19* 티로신은 polar이지만 hydrophobic하다는 점도 써있으면 좋지 않을까 합니다! ### 5/5 — Grape *2025-10-15, version 1.4* Learned amino acids yipeee ### 5/5 — Biochem *2025-10-06, version 1.4* Absolute necessity for memorizing your amino acids ### 5/5 — Best Free Resource. *2025-09-29, version 1.4* If you’re not using this for MCAT prep or Biochemistry go ahead and correct yourself. ### 5/5 — Goat App *2025-09-16, version 1.4* I never write reviews on apps but this actually saved my life on both the DAT and Uni Biochemistry. ### 5/5 — W MCAT app *2025-08-01, version 1.4* Gave the app 99 cents just to support. Such a good app for learning everything you need to know about AAs for the MCAT ### 5/5 — Best app to learn Amino Acids *2025-05-20, version 1.4* I’m using this app to study for the MCAT BB section and by far best way to study on the go ### 5/5 — AMAZING *2025-05-07, version 1.4* I love the creators of the app, I hope you all have an amazing life. Thank you for this amazing tool 🙏🙏🙏🙏🙏🙏 ### 5/5 — Top *2025-05-04, version 1.4* Vraiment super et efficace pour étudier!! ## Most critical reviews (10 lowest-rated) ### 1/5 — Took up an insane & weird amount of energy and drained my battery *2026-06-04, version 1.6* This app took up a crazy amount of energy from my computer. Either it has a bug or it’s sus. It took like 4000 energy impact, while my google chrome (with a ton of tabs open) was less than 200. Idk, I’d avoid. ### 1/5 — Errors *2021-09-16, version 1.2* Cysteine is listed as having a non-polar side chain when it is actually polar. PLEASE FIX! ### 1/5 — Greift auf Clipboard zu *2021-07-09* Bis auf die Benennung von Cystein als unpolar und die fehlende 21. Aminosäure eine super App! 1 Stern gibt es jedoch, weil diese App beim öffnen auf das Clipboard zugreift. ### 1/5 — Doesn’t work on XR after 1 use *2020-08-19, version 1.2* Not working for me, home screen doesn’t load ### 2/5 — Protonation states incorrect *2026-01-21, version 1.6* I started to use to help me prepare to teach sophomore Biochem majors and quickly realized the charge state shown in the structures are incorrect and in some cases impossible. The app missed the pKa factor. If we are assuming these amino acids are at pH=7 then the carboxylate groups will be negative and the amino groups are positive. Also on critically charged amino acids like Aspartic acid the side chain is fully protonated instead of carrying a formal negative charge. Kudos to my colleague, Dan, for pointing this out ### 2/5 — Bad *2024-09-11* Enthält fehler ### 2/5 — Cysteine is incorrect *2020-09-26, version 1.2* Cysteine is polar neutral but in the app it says it is non polar which is incorrect. I hope no one uses this and thinks it’s non polar ### 2/5 — Bonne application mais... *2019-09-12* La cysteine n’est pas apolaire ! En tous cas pas selon les cours de biochimie... et malheureusement aucune possibilité de changer les cartes ou de rajouter des caractéristiques (leurs propriétés ou modification post transcription par exemple...), c’est dommage car elle est visuellement très plaisante ! ### 3/5 — プロリンはアミノ酸ではなく、イミノ酸です。 *2025-10-01, version 1.4* いわゆるアミノ酸の中で、プロリンだけは少し構造が異なるため、厳密にはイミノ酸となります。 　そのため、化学反応においても他のアミノ酸とは少し異なる反応を示します。誤解なきように ### 3/5 — Hydrophilic/Hydrophobic not included *2024-09-19, version 1.3.1* An important characteristic of amino acids is if they are hydrophobic/hydrophilic. It would be great if this was included as well. Important characteristic in most biochemistry classes and for MCAT studying. ## Most praised reviews (10 highest-rated) ### 5/5 — Passed my midterm *2026-05-18, version 1.6* got this a week before the midterm it was looking rough. not only was this kinda fun but it was actually helpful. The only thing I didn’t like is my prof uses “aspartate” and “glutamate” while the app uses aspartic acid and glutamic acid. ### 5/5 — Goatesque 🙏🏻🙏🏻 *2026-03-23* Je sais pas qui a créé ça mais merci je pense que ça a du sauver qql personnes 🙌🏻 ### 5/5 — 10/10 *2026-02-19, version 1.6* Literally amazing. Helping me study for the MCAT ### 5/5 — Quick, Easy, Helpful *2026-02-13, version 1.6* Learned one mnemonic off Tiktok and put it in practice using this app and learned all 20 aa in less than an hour. ### 5/5 — Amazing *2026-02-08, version 1.6* this is seriously helping me for the MCAT. Great reactive interface as well. Paid for the ad free version just to support. Thank you so much! ### 5/5 — Game changer *2026-02-07, version 1.6* So helpful for cramming, helped me memorize all in one day!! Practice every now and then and it keeps the knowledge fresh ### 5/5 — Good tool *2026-02-03, version 1.6* I just wish it kept a record of all my times so I could see it ### 5/5 — Top *2026-02-02* So eine tolle app!! die beste ### 5/5 — Only one critic *2026-01-28, version 1.6* I really wish there was an option to do fill in the blank. After a while the multiple choice format becomes way too easy and a option to put in answers as fill in the blank would not only make it more difficult but aid in studying ### 5/5 — AMAZING *2026-01-26, version 1.6* Studying for my biochemistry exam and the mcats!!! This was an awesome find, love that it’s free with limited pop up adds and super friendly enjoyable interface! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
