Simple and free
If you hate small petty things out of an app that a child would get upset at like the one star review I found on here, don’t get the app. Most adults would have some kind of understanding as to why there’s an element that’s nonexistent on the app. i guess if i were to complain, for people that don’t know their elements, at least separate curiosity away from the table and/or specify that it is not an element. However, i don’t understand how anyone would get upset at that. Most people downloading this app probably know a bit about their elements such as the person that left a one star review. This is a great app that’s simple and free...
The app is great. Though only thing I'd like is the ability to type in values on the sliders instead of having to use the +/- sighs to change the values. But over all it met all of my academic needs and is overall a great resource.
Keep it a clean reference UX without fluff, please
So we finally have the names in place at the end of period 7, which has been much needed ever since they were officially adopted months ago, but then you go and add an eyesore with that curiosity tile. Put it somewhere else in the app if you must. Just get it off of the table itself. It has no place being there. I originally picked this app for being a clean aesthetics reference. I don’t want it to be clogged up with outreach fluff like so many other periodic table apps.
