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.

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.
