Whether you are covering isotopes in a chemistry course, collecting information for work, or simply interested in exploring properties of isotopes, the Wolfram Isotopes Reference App will provide you with all the information you need. This handy app covers almost every isotope out there! - Look up isotopes by name, mass, atomic number, proton and neutron count, and more - Look up isotope properties by the mass, volume, moles, or radioactivity of an isotope - Look up a list of medical isotopes The Wolfram Isotopes Reference App is powered by the Wolfram|Alpha computational knowledge engine and is created by Wolfram Research, makers of Mathematica—the world's leading software system for mathematical research and education. The Wolfram Isotopes Reference App draws on the computational power of Wolfram|Alpha's supercomputers over a 3G, 4G, or Wi-Fi connection. ## Key features - Comprehensive isotope information - Search by name, mass, atomic number - Lookup isotope properties - List of medical isotopes - Powered by Wolfram|Alpha ## Recent user reviews (5 of 5) All indexed reviews: https://appshunter.io/ios/app/wolfram-isotopes-reference-app/id539231445/reviews.md ### 1/5 — From a disappointed nuclear medicine professor *2016-08-23, version 1.2* After an earlier scathing review, I believed the update may have corrected those OBVIOUS errors. Nope, nada, no way! Under "medical" isotopes, a quick glance shows that Tc-99m, I-123, I-131, Xe-133, In-111, Ga-67 are missing and MUCH LESS FREQUENTLY used medical isotopes are listed. Not much need to move on from there although I could. Very poor job folks but I guess you got my five bucks didn't you? ### 5/5 — Tremendously useful *2015-01-31, version 1.2* I'm a professional nuclear scientist. During meetings I often say "There's an app for that!" and whip this one out. ### 2/5 — Unstable in iOS 8 *2014-09-20, version 1.0.0* This was a cool little app for looking up Isotopes and their basic information. However after upgrading to iOS 8 the program has become completely unstable. Hope they get a fix for this soon!! ### 1/5 — Not Worth It!! *2014-07-15, version 1.0.0* As a nuclear engineer with 35+ years of experience, I thought this would be worthwhile app. I was wrong and wasted $5. None of the metastable half-lives are listed. The glaring omission is Tc-99m which is used in tens of millions of medical procedures a year. Tc-99m is also NOT listed under the medical isotope section! Furthermore, if you are going to list isotopes by name, do it in alphabetical order, NOT atomic number order! If you want to do it in atomic number order, present it as a periodic table, where you can click on the element in question. I expected better from Wolfram and have been severely disappointed! ### 5/5 — Excellent Reference *2012-09-20, version 1.0.0* I downloaded this app as a quick reference for properties of different isotopes for the purposes of running a radiation safety program for a military base. To now, I have found no inconsistancies and the information provided has been everything I needed (for each isotope) to verify the hazards and operating procedures which should be necesary for a given isotope. I looked at several other apps for this information and this on appears to be the most complete and accurate that I've found. ## Frequently asked questions about Wolfram Isotopes Reference App ### What is the Wolfram Isotopes Reference App?
