Science is my favourite subject, thankfully they have such thing to help me memorize better, I kinda wish they had for math, advanced math. It would be such a great thing!! ### 5/5 — amo demais *2023-03-09* deve fazer uns sete anos que uso esse aplicativo, adoro jogar kk eu nem sou boa em química mas isto aqui… 🤌🏼 quem criou pode ter certeza da minha gratidão e admiração **Developer response:** Obrigado! ### 5/5 — Ottimo *2023-03-09, version 2.2.0* Divertente, educativa e stimolante (non mi pagano) ### 5/5 — Отлично *2022-12-27, version 2.2.0* Привет ### 5/5 — 잘 쓰고 있습니다! *2022-08-06* 외울 때 너무 편하고 좋아요! 틀린 문제를 다시 볼 수 있는 기능이 있으면 엄청 좋을 것 같아요! **Developer response:** 리뷰 감사합니다! ### 5/5 — No ma manches se merece más *2022-06-04, version 2.2.0* Nice ## Most critical reviews (10 lowest-rated) ### 1/5 — Worst quiz ever *2025-02-26, version 2.2.0* Slay it’s so werid ### 1/5 — 문제 쉬움도 못 풀겠어요🙁 *2022-10-07* 난이도 조절.. **Developer response:** 퀴즈가 너무 어려우면 플래시 카드 및 표와 같은 학습 모드로 시작할 수 있습니다. ### 1/5 — Déjà achetée et payer encore pour pubs. ????? *2021-05-18* Non, non, NON ! **Developer response:** L'application est téléchargeable gratuitement dès maintenant. Lorsque l'application était payante, vous pouviez supprimer les publicités gratuitement. ### 2/5 — App is half ready only *2023-05-21* Without an option to search for a substance the tables are useless ### 3/5 — Лол *2020-05-18* Слишком просто, варианты ответа очевидные ### 4/5 — Chemical substance app *2021-08-04, version 2.2.0* This is a good structured and layed out app, it is easy to download and then you as a uses know what to do. Their is diverent options to choose from that will help you learn and test your understanding of Chemicals.Bea2tman ### 4/5 — Good study tool *2020-08-31, version 2.0* The app has sparked a challenge in me. It provides an opportunity to activate prior knowledge and a creative visual of chemical structures. ### 4/5 — Great App *2020-08-27, version 2.0* This app is a great fun way, when it comes to learning the names and molecular formulas of chemical substances !! Very user friendly,clear and everything runs smoothly. The only shortcoming noted is the fact that one does not have to complete level 1 in order to move to level 2 - thereby there is no point in challenging yourself when it comes to moving to the next level ! But other than that this is a great app and as a teacher in training I will definitely recommend it to my chemistry students one day ! ### 4/5 — Good and room for improvement 😆🙃 *2020-05-27, version 2.0* It’s very good and informative and motivates me to carry on! Here are some things you could add! 1) add some things to motivate the player but focuses on revision, like unlocking sound effects. 2) add something to an achievement to make the player want to revise more 3) the revision cards could be more ordered, for example, they could be categorised into ones that have more than one bonds or which have a specific or similar chemical property. This ensures that the person know that it has more than one bond or has a similar chemical property with another molecule. 4) there could be a starter for beginners and could explain the rules for why hydrogen and chlorine is Hydrogen chloride and not the other way round. There could be starter questions which could help you earn a small amount of light bulbs but are easier than level 1 and 2 5) for more advanced players, there could be test like questions. These could help players get used to questions and understand how to answer them better 6) it would be nice if there could be a motivation buddy, an animated avatar that comments on your progress and celebrates on your positive achievements 7) you could add a banner that asks if you are sure that you want to carry on (use 200 light bulbs) because I keep on pressing the wrong button by accident 8) it would be nice if you extended the app and made a level 3 that does not challenge players to much but is also different in questions and layout, for example, you could make it so that GCSE students or players with difficulty memorising, studying... etc, can improve faster on their improvement. You could make the level more suitable for people with these conditions by using a motivation buddy, it could tell them to do it slowly and you could add music and allow the person to have more or an infinite amount of lives Thank you for reading and I hope you can use some of these tips! Good luck and stay *safe* everyone!!! ### 4/5 — Quick and effective practice *2019-12-22, version 2.0* I really do love this app. As a way to study whenever I have a minute or two free, standing in line, on the bus, when I wake up, it is perfect. I can feel the reinforcement at work. The only thing that would make it even better would be the ability to focus specifically on areas where I am weak, like very similar hydrocarbons, all together instead of mixed in. But at least I’m getting regular reinforcement of everything in between! Definitely recommend for any chem student. ## Most praised reviews (10 highest-rated) ### 5/5 — あらゆる化学物質が網羅されている *2026-04-23* これは面白い。 理学部化学科卒の、IUPUC完読した私でも半分程度の正解率なのに有機無機双方の要素が入っていて、知らなかった物質が出てくると興奮してしまいます。化学と無縁だった人にもお薦めします。これら半分程度でも分かる人は珍しいと思います。樹脂やプラスチックの基本構造が載っているのが貴重です。図鑑代りに使える可能性があります。 ### 5/5 — !!! *2026-01-31* 원소를 외우기 좋아요 ### 5/5 — La adoro *2026-01-17, version 2.2.0* È semplice, intuitiva e aiuta la memorizzazione! Mi piace tantissimo! ### 5/5 — 굿 *2025-08-17* 개맛도리 ### 5/5 — 어? *2025-06-26* 굉장히 재미있게 하고 있습니다. 근데 패드로 하는 경우가 많다보니 가로 형식이 지원이 안 되서 불편합니다. 참고해 주셨으면 좋겠습니다. ### 5/5 — Super app 👍 *2025-03-22* C’est une super application 👍👍👍 ! J’apprends plein de choses, tout est gratuit, et ça marche sans wifi ! Peut-être que l’équivalent des noms des molécules non scientifique serait bien (par exemple : NaOCl : Hypochlorite de sodium (Eau de Javel))… Mais sinon c’est super et je la recommande à tous !! ### 5/5 — Best game *2025-02-09, version 2.2.0* Best game I ever got you can learn from it best game ### 5/5 — 생각보다 괜찮네요 *2025-02-08* 생각보다 괜찮네요 별기대 안했는데 외우기에 나쁘지 않아요 ### 5/5 — 너무재밌어요 *2025-02-03* . ### 5/5 — Fantastica!! *2024-12-02, version 2.2.0* App molto bella e utile l'ho utilizza molto per studiare ed è molto efficace --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
