Most of them are terrible. This one is brilliant. ### 5/5 — Blew me away! *2019-10-24, version 2.3.2* Marc demonstrated this to me and I’ll be honest, I was INSTANTLY blown away. I had no idea how it was done. He uses his incredibly ingenious input method which has shaped a lot of what was to then come to the world of app based mentalism. Buy it now. ### 5/5 — Excellence Again *2019-10-24, version 2.3.2* Another high quality reliable app from Marc Kerstein. Marc’s apps are an investment due to constant updates and improvements on products that were already great to begin with. Earworm is no exception. ### 5/5 — Love it *2019-07-01, version 2.3.1* Simple to use. Very well made. I’ve the iPhone XR and it works perfectly. 10/10 👍👍👍👍👍👍 ### 5/5 — Earworm *2019-06-28, version 2.3.1* This app is pretty slick. Real wizardry for sure. ### 5/5 — One of the best apps you will ever use if done correctly. *2019-03-29, version 2.3* This is a brilliant app if you use it correctly. There are tones of possibilities if you toggle your predictions. The standard performance given with this is good, a little complicated. Once simplified and changing the search text, it will look seamless. Buy it! I think it’s better or on par with WikiTest. ### 5/5 — Earworm *2019-03-09, version 2.2.2* I’ve had this for about a year now, and it is my “go to” routine for attracting new customers in a Social environment, whether it be in the pub, restaurant or just round at someone’s house. I use it in a slightly different way to the instructions, but, in short, this is seriously good value for money. The amount of business this trick has secured me is amazing! Don’t think “should I/shouldn’t I” just do it!! You will no regret it!! Thankyou Marc Kernstein ### 5/5 — Unbelievable *2018-05-16, version 2.0.1* This app is the most powerful magic trick you can imagine. You don’t even touch the phone after the prediction is entered ### 5/5 — Incredible *2018-03-23, version 2.0* Like all of Marc’s releases this is incredible! Anything this guy creates and lets us have is almost invaluable. Thank you so much for your hard work, your constant updates and help with anything I and others around the world seek at times with this and all the other applications you’ve released! ### 5/5 — Great app! *2018-03-20* And Marc is always working on updates for all is stuff. Thank you! ### 5/5 — Music mind reading - incredible *2018-01-18, version 1.3* This is a fabulous concept . Works like a charm . I love this app so much , I would easily have paid double or triple the price for this effect . Buy it now , or maybe not I want it all to myself . ### 5/5 — The mentalism effect for you.. *2017-11-27, version 1.3* What you read on the description is really what you get. Amazing miracle happen on borrowed phone! With one single effect you can choose from numbers of different amazing method that can suit with your performance. Get this! You won't regret it. ### 5/5 — Amazing *2017-03-02, version 1.2.1* Unbelievably clever- works amazingly!! ### 5/5 — Best cheap(ish) app out there!! *2015-09-01, version 1.1* This is an absolute killer! It performs amazingly, and good for walk around. There's still room for improvement (like pebble integration) but with the developer working hard on this, it is soon going to be flawless. Cons: -internet connection is needed for performance (usually not an issue though) - too cheap But really this is an absolute killer! ### 5/5 — Great app *2015-08-26, version 1.1* Awesome effect, does what it says on the tin! ### 5/5 — Endless possibilities:) *2015-04-13, version 1.0.4* This is a worker. Reactions are amazing. You can reveal movies, songs , star signs , sport events, games , food. ## Most critical reviews (10 lowest-rated) ### 1/5 — UNRELIABLE *2023-12-16, version 3.2.2* Crashed not once, but 3 times during a critical moment in a paid performance. Poor resolution after the fact and conclusion of an unstable and unreliable tool for professionals. ### 1/5 — App does not work *2015-03-30, version 1.0* This app does not work. AVOID! ### 3/5 — Out dated *2025-09-24, version 3.2.3* I’m a solo performer so maybe this is different if you have a assistant with you. Keeping it short, now when you try to submit the song their phone won’t automatically go back to YouTube. Apple will ask you “do you wish to open this in YouTube” which ruins the whole thing. You could try to work around it by saying you’re going to “press play for them” but that’s just not as special. I’d like assistance with this if anyone has work around but honestly I think this app now fails because of this. ### 4/5 — Doesn’t support Spotify *2019-10-23, version 2.3.2* I did read somewhere that this app supports multiple services, like on magic cafe. Pretty upset that the developer doesn’t answer my email oh well ### 4/5 — Absolut fantastischer Effekt, in Deutschland leider nicht 100% perfekt *2015-08-29* Also erst einmal: Das hier ist eine wirklich absolut großartige Idee. Und sie ist unglaublich clever umgesetzt. Eigentlich ist die App jeden einzelnen Cent wert (schaut euch auch die Kommentare im Magic Cafe an). ABER: In Deutschland muss ich leider einen Stern abziehen. Erstens funktioniert Youtube wegen der GEMA nur sehr eingeschränkt und zweitens muss man, um die für mich "glatteste" der Trickmedhoden nutzen zu können, vorher wissen, in welcher Sprache der Songtitel sein wird, damit es wirklich gut funktioniert. Trotzdem kann ich die App sehr empfehlen! ### 5/5 — GOD’S GIFT TO MAGIC! *2026-07-20, version 4.0.2* Anything Marc puts together is REAL MAGIC! Buy and don’t think twice!!!!! EARWORM IS ABSOLUTELY BEAUTIFUL!! ### 5/5 — Incredible *2026-06-14, version 4.0.1* I have tried countless apps but none compare to the reactions I receive when performing Earworm. It’s so organic and amazing. So personal and brilliant. Thank you for making this available! ### 5/5 — Good app *2025-07-01, version 3.2.3* I hope i can make good performance, but i meed more often practice ### 5/5 — I never review! *2023-11-14, version 3.2.1* But I do for this. Have only discovered Marc very recently and his explanations are sincerely on a different level to other magic app developers. In the past few days I’ve bought 3 of his apps and the pro upgrade of Wikitest. As success as my business interest are, if Marc was on board they would be even more successful. I intend to nab him. ### 5/5 — Best app *2022-05-18, version 3.1.1* Speechless with the effect! Just try it self! ## Most praised reviews (5 highest-rated) ### 5/5 — Beyond Incredible *2021-09-17, version 3.0.6* There are very few names in the Magic industry that when there name is attached to a product you know it’s going to be incredible. Marc Kerstein is one of those very few names. Earworm is no exception. Highly recommend. ### 5/5 — Love it. *2021-02-12, version 3.0.3* This app is amazing, and definitely a go to! Has not let me down , ever. Highly recommend! ### 5/5 — Please redesign app for ios14 *2020-10-15* Pleeease ### 5/5 — Incredible effect!! *2020-01-26, version 2.3.2* Gets killer reactions. Marc has really thought out the performance when making this. Highly recommend. ### 5/5 — 100% amazing! *2019-10-24, version 2.3.2* A mind blowing magic trick that’s always on you and ready to perform. Highly recommended! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
