Form over function, I guess. ### 4/5 — Where is 113? *2018-12-16, version 3.0.16* This game is very interesting and it taught me so much BUT... where is element 113, 117, 118, 119, 120, 121, 122, 123, 124, 125, 126 or 127? From Adam ### 4/5 — Needs a search feature *2018-08-22, version 3.0.16* Great. But if you don’t know or remember an element’s abbreviation, good luck. I had to go to Google to find Tungsten, W. It’s been a few years since high school chemistry class. A search feature would be great, and one that forgives spelling even better. ### 4/5 — Iphone X update *2018-06-01, version 3.0.16* Can you update the app to fit the iPhone X’s screen please? Otherwise great app thanks!!! ### 4/5 — Helpful *2017-03-05, version 3.0.16* This app is good and easy to use but I think you should add the charges of all the elements. Thanks ### 4/5 — 113, 115, 117 and 118? *2016-08-19, version 3.0.16* Really nice app, but needs to be updated to figure the 4 new elements that have been named (113, 115, 117 and 118). ### 3/5 — Would seem to require some updating! *2016-08-02, version 3.0.16* This is great for basic information but some of the most recently identified or named elements have not made it to the list. Please will you oblige and update? ### 4/5 — Nice! *2015-09-23, version 3.0.16* Easy to use. The only thing: a search bar would be nice. ### 5/5 — Great update! Awesome app. *2015-05-05, version 3.0.16* Vast improvement with the user interface. Can give enough "thumbs up" on this. Great app. ### 5/5 — The only good free periodic table app *2015-05-05, version 2.2.7* I absolutely love dragging the cursor without being directly on top of it. Now I can see what I'm doing without my finger getting in the way. ### 3/5 — Righto *2015-05-05, version 3.0.16* I'm BazzaTheBird and this is informative but not very fun maybe implement some games for my child like mind ### 5/5 — This was the first periodic table I got for iPad and probably the best *2015-03-25, version 2.2.7* This app has all the essential information including the Lewis dot graphs. A must have! ### 5/5 — Gr8 *2015-01-29, version 2.2.7* Dis helped me get a b+ in English kkkthanks ## Most critical reviews (10 lowest-rated) ### 1/5 — Needs to be updated *2023-09-14, version 3.0.16* This app is missing 5 elements. Definitely needs to be updated. Sad since it was my favorite periodic table. ### 1/5 — Review *2018-11-15, version 3.0.16* Good but bad ### 1/5 — Milf *2018-09-07, version 3.0.16* ios.miekute.info ### 1/5 — Meh, needs an update *2017-10-09, version 3.0.16* Doesn’t rotate automatically to landscape anymore. Needs an update for iOS 11. The selected element is too large to see the surrounding elements so you have to click around if you’re trying to find an unfamiliar element. ### 1/5 — Don't recommend *2016-01-11, version 3.0.16* The Lewis dot structure is very lacking and is wrong on the ones it is concluded in have the structure put in the wrong spots. The transition elements are missing the structure , and they misspelled some of the elements. ### 1/5 — Crap *2015-04-26, version 2.2.7* Crap ### 1/5 — Missing *2014-06-26, version 2.2.7* Any one considering downloading this app should not because it is missing 3 of the elements of this world(Ununtrium, Ununseptium, and Ununoctium) ### 1/5 — Just a tip *2014-02-21, version 2.2.7* A tip to people just downloaded the app, don't hit anything otherwise the whole app will crash! ### 1/5 — check ionic radious of chlorine *2013-10-10, version 2.2.6* actually is 181 pm, but you got something different that makes me loose lots of minutes figuring out what was going on that i was wrong on my exercise ### 1/5 — Would love to use this but... *2013-06-23, version 2.2.5* Every time I try to open this app my whole iPad freezes & I have to power off to get going again, 😥. ## Most praised reviews (10 highest-rated) ### 5/5 — Good App *2023-09-22, version 3.0.16* I felt really like I was learning a lot about chemistry and the periodic table while using this app, and hope to see more in the future. Best periodic table app out there right not! ### 5/5 — Great for science students! *2021-04-27, version 3.0.16* The app is great for those who are doing the sciences and would like to find information about the elements or would like to study. The app is really easy to use and has a vast amount of condensed information. I definitely recommend getting it. ### 5/5 — Needs new elements *2021-01-28, version 3.0.16* Add 113 (Nihonium, Nh), 117 (Tennessine, Ts), and 118 (Oganesson, Og). And also change the name of Ununpentium (Uup) to Moscovium (Mc). I still love the app though. ### 5/5 — nice *2020-10-21, version 3.0.16* nice ### 5/5 — SERIOUSLY SO HELPFUL!! *2018-08-14, version 3.0.16* This application blows the other periodic table ones OUT OF THE WATER. It’s simple, easy to use, and modern. While others look complicated and give a little TOO MUCH detail, this is ABSOLUTELY PERFECT!! ### 5/5 — Gr8 app *2017-05-22, version 3.0.16* Such a good app for homework, shows you all the information for all the elements! I love it! ### 5/5 — Love it *2015-11-16, version 3.0.16* It is perfect but it need's a search bar ### 5/5 — Really well put together *2015-09-15, version 3.0.16* Nice clean app, not too busy. I love that it has valence electrons and Lewis dot structures. Awesome app very much recommended. ### 5/5 — Spelling mistake *2015-09-10, version 3.0.16* They spelt cesium wrong. Other than that, it's a fine app. ### 5/5 — Loves it *2015-09-03, version 3.0.16* Soooooooo helpful at school --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
