Nobody needs a subscription to a periodic table
Please don’t take this the wrong way, as I understand that you put time into developing the app. But I noticed just now that you seem to have delisted the single-purchase version of this app that you made and have now switched to a subscription service for the pro version on this app.
I noticed this when I had accidentally deleted the single-payment pro version I had previously purchased from you and needed to go into my past apps to find it, as it’s no longer in the app store.
I want to say this as gently as I can: nobody has any need for a subscription-based periodic table. The prices you are asking for are also absurd. You are charging for a periodic table app of middling quality (the UI/UX is rather poor), and this isn’t even something where a subscription model makes sense. There are too many free periodic tables (e.g., ptable.com) to justify wasting money on subscribing to a periodic table app.
To others reading this; please save your money. This developer used to offer a pro version of this app for a one-time fee (<$10). I don’t remember the exact cost but it was not expensive. Now, returning to it, I see that subscribing to a pro version for even a month is more expensive than lifetime access used to be.
This developer seems a bit greedy. I think you, dear reader, deserve better and can find better.

Should add accounts feature
Good but should add an account feature to save subscription on other device. Optional to sign up or log in though.
之前買2025的版本
現在更新到2026我之前有買2025，新的2026還要重新付費嗎？無法恢復購買嗎？

Great app for chemistry enthusiasts
Prices can be a bit low

Thank you so much for the feedback! I'm glad you're enjoying the app and hope it stays just as helpful for you.
Ionization color?
When I saw neon was represented as orange, I thought “wow the graphic is accurate to the actual ionization color” but when I saw xenon its graphic was blue, so that was a disappointment.

Periodic Table - Approved by Mendeleev !
Liked the app. It’s fun to work with it. Useful for you if you work in a chemistry-related field or you’re just an enthusiast.
Wrong!!!
I’m 9 and when I got this app I got really excited but when I learned more I saw mistakes and more mistakes and now I hate this app.

안녕하세요! 좋은 리뷰 남겨주셔서 정말 감사합니다! 주기율표를 재미있게 공부하고 계신다니 정말 기쁩니다. 보내주신 성원은 앞으로 앱을 더 발전시켜 나가는 데 큰 힘이 됩니다!
Harika!
Tam bir kimya uygulaması her detayı düşünmüşler sadece tablodan ibaret değil çocuklar için çok faydalı olur tavsiye ederim!
Love the app, hate the lack of support
I adore this app, and paid for lifetime access to enjoy all of its features.
After only a month of lifetime access, I opened the app today to discover that it was gone. My access to the premium features is locked out. So I went looking for customer support, and found dead ends everywhere. I even tried to click “report a bug” to flag this issue, but every time I click “report a bug” the app crashes.
I’m hoping that posting this review will get me in contact with the creators who can restore my purchase and maybe fix these things!

Adeus Cu e olá Ho o elemento do 67 amei aprendi com esse aplicativo incrível simplesmente incrível,quando estou entediado eu fecho o Duolingo e abro o tabela periódica e aprendo piadas de química(não é uma funcionalidade do app)eis a piada que criei

Great app and great customer service
Great app and great customer service
Good but
Great deep professional app for chemistry. One question. I have 2 here( basic-keeps opening taking up room- then a short note brings me to professional chemistry app. I mean depending on needs both are outstanding. I just am unsure if I’m going to have 2 forever
huge information
..but needs more updates, e.g. link to wikipedia goes only to engllish version. Why not adjustable ?
App in german, so link to german wikipedia.
For further improvement now i‘m testing..

Question was taught good lesson and learned chemistry from the app that’s good design maybe it was luck or something like a chemical relationship they just know what I mean thanks again pals
