I welcome this change but somehow this appears to have been done without an actual App Store update. Wish I knew in advance because I didn’t notice the change until after I broke a string while tuning lol! ### 2/5 — リニューアル後　性能が酷くなってしまった *2023-06-15* リニューアル後、3回か4回弦を弾いて その弦をまともに認識出来なくなってしまってます。 早期の改善を求めます。 よろしくお願いします。 ### 3/5 — Better before the update *2023-05-01* Love that you added 528hz but it’s not as responsive or accurate than it was before the recent update. Slightly disappointed. ### 2/5 — Input not accurate *2020-08-11, version 4.1* I tried this with my guitar and it doesn’t seem to pick up the sound accurately such a shame ### 2/5 — The developers are aware this app doesn’t work with iPhone 11 *2020-08-01* I purchased this tuner the night before teaching a lesson on healing frequency tuning because the battery had died in my clip on tuner. I was very disappointed to find that the app doesn’t detect anything from iPhone 11. I read some other reviews confirming this and then reached out to the developers. All they said was a known problem that that are trying to fix (and they’d reach out but that was 2 months ago). I do appreciate that but I do wish they would make that known in the description so that people don’t purchase an app they can’t use. I am grateful that is type of app exists and wish the developers luck in resolving the issue. **Developer response:** Hi there, we've released a new version of the 432Tuner which addresses this issue, please download the new version (4.3) and see if it works for you. If it works I would truly appreciate if you can update your review :) I can only say the I'm sorry it took so long to fix, it was a hard bug to find. Much blessings, 432 Team ### 3/5 — Apps not working *2020-07-13* Hasn’t been picking up sound since last update. **Developer response:** Hi there, we've released a new version of the 432Tuner which addresses this issue, please download the new version (4.3) and see if it works for you.

Much blessings, 432 Team ### 1/5 — Doesn’t work *2020-05-30* I have the iPhone 11 Pro. The app doesn’t register that it is picking up sound. I have deleted it twice, downloaded it three times, rebooted my phone twice, and even updated my phone and redownloaded it after that. Nothing has resolved it. I open the app, ALLOW it to access my phone’s mic, and then make a whole bunch of noise, but the virtual needle remains on the default “C”. Nothing changes. Ever. Bummer. **Developer response:** Hi there, we've released a new version of the 432Tuner which addresses this issue, please download the new version (4.3) and see if it works for you.

Much blessings, 432 Team ## Most critical reviews (10 lowest-rated) ### 1/5 — SCAM ALERT *2024-06-09* It doesn’t look like it but as soon as you downloaded it it charges you $9.99 ### 1/5 — Don’t buy it *2024-03-27, version 5.0.0* Crappy! Period no exclamation point!!! ### 1/5 — Update Ruined the App *2023-05-04, version 5.0.0* I don’t know why they did this, but their update changed the format and now it doesn’t keep any tune. They killed the app and I paid money for it. Unfortunate ### 1/5 — Waste of money. Doesn’t work properly *2021-03-30* Doesn’t even tune correctly. I’d like my money back. I’d have been better off buying some lunch! Rip off. ### 1/5 — It’s not like it shows! *2020-09-09, version 4.3* The interface it’s different, looks like a compass, when I tried to “tune” to 432 the guitar sound became all wrong! ### 1/5 — Ripoff *2020-09-02* This app does not work at all. You can select the hz but that’s. The microphone function even tho turned on does not work. I want my money back! **Developer response:** Hey there, Please download the latest version of the app (4.3) it should work now. If it does please update you review. Much blessings ### 1/5 — Does not work. *2020-08-12, version 4.1* Cannot get this app to do anything. Does not work. ### 1/5 — JUST A Picture *2020-07-21* The app does not work **Developer response:** Hi there, we've released a new version of the 432Tuner which addresses this issue, please download the new version (4.3) and see if it works for you.

Much blessings, 432 Team ### 1/5 — Listen to other reviews, doesn’t work. *2020-07-17, version 4.1* Doesn’t recognize any sound. Can’t tune. Waste of money. Try elsewhere. ### 1/5 — Nothing *2020-07-02, version 4.1* Does nothing ## Most praised reviews (10 highest-rated) ### 5/5 — Excellent *2023-10-15* Perfect for when I’m not in reach of a tuner, out and about where there’s a guitar around ### 5/5 — Great app! *2023-03-27* I’ve been using this app for a while especially to tune up my ukuleles for recording and the finished tracks always sound cleaner and much warmer when recorded at 432 rather. than in 440hz. The 528hz tuning sounds much brighter with more clarity and tends to fit much better with vocal tracks too! Is there any way the app can be downloaded to the phone so I don’t have to keep returning to the App Store to open it? ### 5/5 — App works *2021-01-14* 432 is better for you ### 5/5 — Wont work with iPhone xs *2020-11-09* I think the app doesn’t work with my iPhone, i cant select or change anything with that, overall I didn’t understand, if anything plays on your iPhone after that you can change the pitch to 432hz At the same time? ### 5/5 — Bug fix works brilliantly *2020-09-03* Took a long time, though I re-love the app again. ThankYou creator/s **Developer response:** Hi there, we've released a new version of the 432Tuner which addresses this issue, please download the new version (4.3) and see if it works for you.

Would highly recommend for the Day Trippers! ### 5/5 — Always a pleasure *2020-05-14* This is my Go to app when I don’t feel like using my hardware tuner. Makes my ukuleles sing ### 5/5 — It works *2020-05-12, version 4.1* A great app-based tuner.
