Did the App Store remove this app? Tried everything, still won't download with same error message. ### 2/5 — Bad app *2013-07-15, version 1.2* I am using iPhone4S, downloaded the app, tried to start the program at 3:05pm and never worked. The track is not in my music list as well. =_= ### 3/5 — Needs work, but great idea *2012-07-20, version 1.0* I started the app literally a second before it was suppose to start and it would not start for me at all. Just said thank you for participating. The app should start are the correct time and sync with everyone at the same time. It worked for my cousin but when she locked her iPhone it turned off and she went back in and had the same message. Luckily she downloaded the back up. Pandora the radio app, for example, plays music and does not shut off when locking your iPhone. This year was my first year as was the app and I look forward to it working better for next year! Great idea! ### 4/5 — Good, but needs work *2012-07-16, version 1.0* I like everything- the app is pretty well created, but the mp3 experiment wasn't easier with the app... When I locked my device at 3:01 , the app was still opened but playback stopped and going back to app, it said - 'thanks for participating ; the event has now ended' ... For next year, try to fix the app do it resumes playback in the correct place in case it closes (: otherwise, nice job! ### 5/5 — Works Well! *2024-06-21, version 5.0.10* The app has worked perfectly for me over the last several years. I use it once per year at the events among all the many other participants and have not noticed or heard of the app not similarly operating properly and easily for others. That’s my experience. Simple, nicely functional and fun! Enjoy The Mp3 Experiment! ### 5/5 — So much fun! *2023-08-28, version 5.0.10* I look forward to the Mp3 Experiment every summer in NYC! It’s always a joyous blast. The new version of the app worked perfectly this year. Thank you! ### 5/5 — Works flawlessly *2019-06-16, version 3.0.5* The update they made to this app is awesome. Works perfectly. What a fun way to get a big crowd of people in sync. My family goes to the NYC event every summer. ### 5/5 — Love It *2014-06-28, version 1.2* I love Improv Everywhere and I'm so happy I can access all of the missions at the click of a button! ## Most praised reviews (6 highest-rated) ### 5/5 — Charlie *2013-05-01, version 1.1* So creative! ### 5/5 — Awesome *2013-03-04, version 1.1* Improv Everywhere is amazing and so is this app :) ### 5/5 — Awesome people *2012-12-02* I love this guys their the best. ### 5/5 — I love it!! *2012-10-24, version 1.1* I LOVE the website, and the app is just perfect for watching it on my iPhone.
