If it worked with the Apple Watch, it would be wonderful. ### 1/5 — Good App but… *2025-06-18* This is a great app, but it is dependent on the iOS version, phone version, and ***** version. Worth a try. It might work. ### 5/5 — Great app *2024-05-26* Can’t get ahold of you but great job tho it does need an update first try it’s just a prediction automated then it works fine ### 5/5 — I love this app! So organic! *2024-02-04* I performed this all night tonight at my restaurant! I’m using it in conjunction with a printed on my AirPods case and it’s now found a permanent place in my repertoire. I love that it’s also part of my EDC so I can always be ready to perform it. I saw a couple other folks suggested it also be ported to have Apple Watch capabilities. I echo that. It would be nice to have. ### 4/5 — Wont work with older Airpods *2024-02-02* I’m really excited to try and perform this trick, but I don’t have any of the newer air pods. I only have gen 2. Why wont they work with this trick? ### 5/5 — Important Tip *2023-12-31, version 2.0.1* Your ringer must be on for this to work. I recently performed this and the phone didn’t vibrate as it has always done. The routine flopped. When I got home I noticed my ringer switch on the side of my phone was set to silent. Apparently this cancels the vibrate/tactical feature from the app - as the visual feature still worked so I knew they were connected. I switched my ringer on and now it works perfectly. Have fun! ### 4/5 — Fantastic but needs some additions *2023-12-19* Fantastic app and it works well, I only have two issues at the moment. First the app keeps crashing so hopefully that can get fixed. Secondly I have everything figured out except how to transfer the data to a shortcut notes for the prediction, so maybe adding on video tutorials would help. Thanks! ### 5/5 — Near perfect *2022-04-01* Love this. I’m hoping you all consider porting this to the Apple Watch. ### 5/5 — Works great *2021-10-06* Did not work at first... had to go back to older version of app once that worked updated to newer versions all works well now ### 2/5 — Why just AirPod pros? *2021-07-02* Can u make this compatible with AirPods already? ## Frequently asked questions about Echolocation ### What magic routines can I perform with Echolocation?
