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?) ### 4/5 — Nice introduction *2018-07-16, version 3.0* As an ‘oldie’ just getting interested in this subject I find this very useful. 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 ### 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. ## Frequently asked questions about Particle Zoo ### What is Particle Zoo?
