We have been comparing laptop and device quality at the office and have seen some very interesting results between the different models. Works great on my iPhone 4s and iPad retina with no issues. Haven't updated my iOS yet though. ### 5/5 — A fun way to explore science. *2013-04-23* Backed it on kickstarter. Lots of fun! ### 5/5 — Awesome app, works as advertised! *2013-04-16* This app (and hardware) is great fun. It's very addictive to check radiation in every house you visit. I'm driving everybody nuts, wanting to check every device in their home. Great for kids too, they love it! Thanks guys for creating such a cool addictive app. ### 4/5 — K *2013-03-21* I have the attachment and it is working great! Picks up really high EM readings where it should and gives a good low number base reading. ### 5/5 — Amazing *2012-12-27* I will look closer for minor bugs but this app is bug free mostly and it works amazing with the emf detector from the kick starter early bird special :) ### 5/5 — CTO Media Li2ght Entertainment *2012-12-21* Great design and the iPhone Mobile Application complements the product very nicely! ## Most critical reviews (10 lowest-rated) ### 1/5 — :( *2017-11-21* Please update this to work with iOS 11, I loved this app ### 1/5 — Needs An Update *2015-05-03* Worked great on my old phone, since I got an iPhone 6 it just doesn't work right... ### 1/5 — DOES NOT WORK ON IPHONE 5S *2014-09-16* I was super excited to purchase this product... Until I got home and found out that it does not work on the 5S. Had I known this beforehand I would have never waisted my money on it. VERY DISSAPOINTED!!! ### 1/5 — Doesn't work with 5S or... *2014-04-15* ...it's soo fragile it breaks before you get it in the mail. I've gotten three of these antennas now and Not One works with my iPhone 5S with the latest iOS. This entire process has taken over a month in a half. I'm getting my money back from ThinkGeek. Only good thing about it all was the prompt email assistance you will get with the guy that owns the product. Still, looks cool, sounds cool, but my experience sucked. All very very unacceptable. ### 1/5 — The Nothing Detector *2013-11-10* I got suckered in by this one. It won't detect anything more than two inches away. If it's that close I don't need a detector. ### 1/5 — Useless *2013-04-16* So disappointed, after updating my iPad especially for this app, it does not work. The reading is fixed even besides a stupid old microwave... Wasted money until a fix for ios 6.1.3 update... ### 1/5 — Not compatible with iPhone 5 *2013-03-21* There's an odd whit bar at the bottom of the app. No indication of how to switch between modes after a mode has been chosen. App has crashed twice in the first 5 minutes of use. Bummer... ### 2/5 — Not quite ready for prime time *2013-03-23* White bar at the bottom. Works great as a sound level meter, but does nothing with my Mr. Ghost. No modulation of the EMF signal near any device in the house or at any sensitivity setting. Do I have a broken unit? No way to troubleshoot as there are no informational resources or guides that I have found. And the "manual" that comes with the device is pretty sparse. Cheap yes, but non-functional so far. ### 3/5 — Needs immediate feedback *2014-06-28* The visuals execute alright on the iPhone, but the fact that I cannot hear the EMF audio as I wave the iPhone around and the fact that it picks up actual sound waves too doesn't work out very well. I usually end up pointing the phone at anything that reads high enough only to find out the crackling sound it made was pretty lame. ### 3/5 — Good but couldn't get glow mode *2014-05-07* The settings and ease of use is good but I couldn't get glow mode to work. After sliding all the way to a dark screen, nothing happened I tried many times with no success. ## Most praised reviews (10 highest-rated) ### 5/5 — Works great *2014-12-10* I don't know what problem the other reviews have had but I've had the mrghost app for a while now and it and the antenna work perfectly fine on my 5s I'm constantly using it around my house and job. 5 stars for this perfectly functional and amazing app ### 5/5 — Awesome *2013-09-06* Mr ghost is a great app for entertainment. I found out my friend is ghost :-) ### 5/5 — Very fun and interesting to see what it reveals. *2013-04-28* Well done! ### 5/5 — Great app and product *2013-04-23* Aaron - great job with this app and Mr Ghost. I'm looking forward to the spectrum analyzer update. ### 5/5 — Great widget *2013-04-23* I really like Mr Ghost. Aaron the developer tries his best to fix problems ASAP. It's great for finding what things in your house are putting out EM radiation. My plasma TV was off the scale. Remember you need the Mr Ghost antenna for it to work. ### 5/5 — A lot of fun with Mr Ghost & iPhone 5 *2013-04-23* Been quite entertaining to 'see' what was before invisible to me. Works quite well, does take a little adjustment (as per instructions). Note that this app must be paired with the external mr. Ghost sensor. Using this app by itself will lead to an unsatisfactory user experience. ### 5/5 — Great app. *2013-04-23* MrGhost is awesome combined with the mrghost device. Keep the updates coming. Specially exporting recorded wav 's to Dropbox. ### 5/5 — This thing is so cool! *2013-04-23* Glad I managed to get in on helping fund this project on kickstarter. ### 5/5 — Another Showcase App *2013-04-23* Very happy to have backed this Kickstarter project and having lots of fun using the App and antenna around my environment. Great to see the promised enhancements coming through. ### 5/5 — Excellent *2013-04-23* Great features and works well. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
