iSpartan

It’s really a good app. But is it possible to Input the file such as Gaussian output file from other calculation software?

I use this app in the classroom to show conformational energies, orbitals, charge distribution, IR and NMR etc Students love it. App works by drawing a structure and if it's on the company server it downloads all available data. Current iPads, A10 chips and later, can easily perform most quantum chemistry calculations at the semiempirical, HF and DFT levels, it would be great if the developer included the possibility of performing actual calculations on the iPad using a ARM compiled version of QChem and the GUI of this app. Please bring a version of the real SPARTAN to the iPad !!!!!

This app is amazing, however in order to access the extended database you must purchase the parallel suite for your computer and submit your sketch remotely. The parallel suite is costly, and it is difficult to find a way to buy an individual student use version on the website.

Well, this is my new favorite app, EVER. I use spartan at the university, but I didn’t expect the app to be as good as it is. It gives spectra for molecules and even demonstrates what the stretch/bend looks like on the molecule if you hover over an absorption/peak value. What?? Crazy! Easy to use, definitely worth money!! (I’ve been sitting here sketching/evaluating molecules with this app for the last 5hrs), this is awesome! Would absolutely recommend it.

I had to obtain this for a class and do not think my professor knew how much of a pain the app is. Some of the issues I have had are: to add a ring you have to tap multiple times (certain my phone is not the issue), you are only allowed to go back once, multiple taps needed to delete anything (there is tremendous room for improvement when it comes to precision), also it is unclear if the lone e- symbol represents an e- pair or is a single e-, and there are no instructional videos for the app on YouTube or spartans website. I think once these issues are fixed it will be an awesome app but for now it is very frustrating to use and time consuming. To professors it would be better to require students to obtain the pc version because the app is not well developed and lacks instructional resources.

Paid for the app but difficult to work with. Wish I had not paid for it. I prefer the orange NMR for free for what I needed to do. Would not recommend.

iSpartan gives you a ton of features for a pretty cheap price. I use this app to show functional groups in 3D in my undergraduate organic lectures. The computed IR spectra, while they don't resemble what you would observe from an instrument, assign the various stretching modes to each bond type. This really is cool for demonstrating to a class why IR is useful. The NMR predictions are nice as well for showing why hydrogens and carbons have different chemical shifts. I recommend this app to anyone learning or teaching organic chemistry.

I could write a whole page if I wanted praising this software as it's by far one of the best apps I've ever used. But limited by time & space, all I'll say is if you're serious about chemistry, everything I own by Wavefunction is of the highest quality and a MUST HAVE! Every penny they ask for is worth it as these folks have gone above & beyond your wildest expectations. Ease of use & incredible accuracy can't be duplicated anywhere for what these folks ask for. As a 2nd year Organic Chemistry major, this software has taught me almost more than my instructors, & has definitely reinforced my learning. Most folks are visual & trust me, this is eye-candy! Highly recommend, you won't be disappointed. Reading some of the negative comments are completely wrong & lead me to believe they don't have this software or have ever used it. You will be impressed!!

Nice app that actually works. Nice to show IR bands and show conformer analysis.

It’s superb for structure building and display. There are some other cool features too. I highly recommend this app.
