About this app

A chemistry reference that works on a plane.

Periodic is a education app from Tilde Software. It was built around one idea: give people a tool that opens quickly, works when the network does not, and does not ask for an account before it is useful.

What you get
• Full element data offline
• Equation balancer
• Molar mass calculator
• No account, no tracking

How it behaves
Everything that can happen on the device happens on the device. Where Periodic does need a server, it tells you before it sends anything. Settings are plain, exports are open formats, and nothing is locked to this app if you decide to move on.

Periodic is a one-off purchase. There is no subscription and no advertising.

Tilde Software reads every support message. If something is broken, write in and it gets looked at — the release notes name the people who reported each fix.

  • Worth every penny

    Does one job and does it properly. Battery use is negligible, which I cannot say for the alternatives. Recommended regardless.

  • Not what it was

    Was great until the last update. Now it crashes whenever I open the settings screen on Android 14. Worth the money.

  • Quietly excellent

    Been using this for about four months now and it has not let me down once. Support replied to me in under a day with an actual answer.

    Bilal Q. · 2 months ago · version 6.10.5 · 416 found this helpful

  • Finally

    Does one job and does it properly. Starts instantly even on my old phone. Happy to raise the rating once it is fixed.

    Ines C. · 3 months ago · version 6.10.5 · 349 found this helpful

  • Promising

    Good core app, a few rough edges. The widget resets its size after a reboot. Will update this review if that changes.

    Daniyal R. · 4 months ago · version 6.10.5 · 218 found this helpful

  • My daily driver

    Exactly what I wanted and nothing I did not. Starts instantly even on my old phone. Recommended regardless.
