It is however unfortunate that a lot of the links don’t work. ### 4/5 — Disappointed *2018-01-22, version 3.0* The app used to have more particles, and space time as well. I hope the devs are working to bring them back. ### 4/5 — Please Update. *2017-11-13, version 3.0* I would give it 5 stars but it no longer works on my iPhone 7 with ios11. It explains so much. So Please update when you get the chance. ### 4/5 — Update Please *2017-10-19, version 2.0* Please update this app for IOS 11. My son is into physics and this will be fun for us to share ### 4/5 — Help me *2013-09-30, version 2.0* How do you get to the build a baryon ### 3/5 — Fun app, but... *2013-08-30, version 2.0* What happened to the beta decay simulator? What happened to build-a-baryon? Those were awesome! I want them back! :( ### 4/5 — Buttons *2013-07-11, version 2.0* Some of the buttons do not work and the Higgs boson is under boson but labeled theoretical! ### 4/5 — Awesome *2013-03-17, version 2.0* Great job never seen a better app ### 5/5 — Jake says Awsome! *2013-02-19, version 2.0* This application is completely worth downloading. Very useful, well structured and fun to work with. Excellent reference for learning about physics, sub atomic particles and other great stuff. Don't pass this Application up. Download now and rate it! ### 5/5 — Particle zoo *2013-02-02, version 2.0* Nice. Good way to review and keep track of all the fundamental particles and Epochs of the Universe. Probably only worth it to those who have already studied the subject and need reminders of what they learned ### 5/5 — This app is awesome *2013-01-17, version 2.0* That is all. ### 5/5 — Adorable App *2013-01-16, version 2.0* What can I say, I'm a sucker for Quantum Physics cartoon-like characters. This is a great reference for understanding (and remembering) subatomic particles, especially for anyone (like me) who has problems confusing the qwarks with the bosons and all their friends. Worth checking out! ### 5/5 — Amusing *2013-01-04, version 2.0* I have an iPod 4 so I was able to download it with ease. It is really cool and it has a lot of particles. Really cool app. ### 2/5 — Poor *2012-12-29, version 2.0* What's this for... ### 5/5 — Awesome! *2012-12-08, version 2.0* And wonderful geeky to boot. ## Most critical reviews (10 lowest-rated) ### 1/5 — I only hate this version *2014-01-08, version 2.0* They got rid of build a baryon that was a great feature :( ### 1/5 — Because *2013-09-23, version 2.0* Blarg ### 1/5 — IOS 6.0 *2013-05-13, version 2.0* Why update this to require IOS 6! Ipad 1 does not support this. ### 1/5 — Particle Zoo *2013-01-30, version 2.0* I think this app is helpful, it shows you about different particles. But it isn't very helpful you don't really learn much. I think it is two easy I wound not recommend this app to many people. ### 1/5 — Broken on ios 5 *2012-12-23, version 2.0* The "quick update for ios 6 compatibility" now requires ios 6, and doesn.t work on or install on earlier ios. Mistake. ### 1/5 — Why requires iOS 6.0? *2012-11-15, version 2.0* This version makes older versions of iOS 6.0 cannot update. It is not necessary so. ### 1/5 — Doesn't work on iPad 1 *2012-11-02, version 2.0* Updated to IOS6 ONLY. Can't even update it because of this, sits in the update folder greyed out... Forever. ### 1/5 — Unupdatable update *2012-11-01, version 2.0* Latest update drops first gen iPad support. Will have to see it in my update list for eternity without ability to update. ### 1/5 — Not working with OS 6? *2012-09-26, version 1.5* Too bad. I can't get to see anything but 1 particle....bug...maybe because of OS6? Would love an update to fix this... Franki ### 1/5 — Crash!!!! *2010-04-15, version 0* The game didn't crash, my IPOD crashed!! It took me 10 minutes to get the screen to be anything but black with Apple's logo on it!!!!! ## Most praised reviews (10 highest-rated) ### 5/5 — What I Think We All Want *2024-03-10* This is a good app, I’ve seen some Imgur posts about the app’s early version. I do want to see Build A Baryon and more particles, or as I call them, “Zoo Critters”. Besides, in app’s early version, there were some “Zoo Critters” weren’t even made into plushies! But it’s a very interesting and informative app. Adieu! (Also, can you make the Critters animated?) ### 5/5 — Fun, Colourful, Easy to Use *2016-08-13, version 2.0* We could use more educational programs like this one! ### 5/5 — Efficient and fun! *2015-02-17, version 2.0* 👍 ### 5/5 — Great app *2014-10-16, version 2.0* This app contains accurate information in a pleasing layout. I would recommend it to any one who likes science ### 5/5 — Great App - Handy Ref w/ Basic Info *2014-08-18, version 2.0* Nothing to deep but it gives basic info on a veritable zoo of particles and some other info. ### 5/5 — Beautiful *2014-05-03, version 2.0* This app is truly magnificent and one of a kind. You may find it a bit 'quarky', though. My only complaint would be that the links in the descriptions don't function. Also, the Higgs Boson is still listed as "Theoretical" in the left category bar, despite the colour of the left category bar being the same as the bosons. ### 5/5 — Awsome *2014-04-29, version 2.0* I'm only in year 9 but I understand every word so brilliant app. ### 5/5 — ITS JJ *2014-04-15, version 2.0* Hey it's your kid good job rick ! ### 5/5 — Great app *2013-11-03, version 2.0* Great app. Very informative. It tells you what you the basics to almost everything in the universe. And the pictures are pretty amusing. I would highly recommend this app to anyone interested in learning about the universe. ### 5/5 — LOVE IT! *2013-03-02* This app is awesome and I use it frequently. Kudos to you. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
