Only problem is if I try to search for different tuning systems it draws a blank suggestion box. if I click on the blank suggestion box it will change the tuning system, but I cant see what it has changed to till I click on it, and cannot get it back to the previous setting. I’m guessing this is due to my old iPhone 8+, but just thought I’d drop a line about it. ### 4/5 — Works amazingly! *2025-05-13, version 3.0* Everything on this app is very good, and it’s great to support a musician who made a great app. My only issue is that my phone is predominantly on dark mode, and when dark mode is on the list of temperaments disappears. This is my only problem. ### 2/5 — Needs an update !! *2024-01-16* I agree with Duncan! When I turn dark mode off I can see the temperament list. Otherwise it is blank and kind of like a game of pin the tail on the donkey. **Developer response:** I'm sorry I didn't get your email. It should have worked really well on your device. Please try out version 3.0 that's available to you as a free update. If you still have trouble with it, reach out to me at niklas@saers.com ### 5/5 — Lots of tuning options *2023-12-28* This app allows one to tune very precisely! Unfortunately in the newest update the list of temperaments does not show up when your iPhone is in dark screen mode (just a white screen until you guess at one and then it is entered). But it works just fine if one is not in dark screen mode! Must be a font/color issue **Developer response:** I'm sorry for not getting back to the comments earlier. At the time you wrote this, it should have been working great. Please check out version 3.0 that you should be a free update for you. If it still doesn't work, do reach out to me at niklas@saers.com ### 2/5 — Needs an update !! *2023-11-24* Needs an update! Doesn’t talk to the mic on Iphone xs os12.1 ! Love the temperament selections. A small tweak would fix all this. Emailed the admin with no response! **Developer response:** I'm sorry I didn't get your email. It should have worked really well on your device. Please try out version 3.0 that's available to you as a free update. If you still have trouble with it, reach out to me at niklas@saers.com ### 1/5 — Feedback issues *2023-11-03, version 2.1* Tuner appears to feedback with my phone and iPad microphone producing a high pitch piercing feedback sound and does not register the pitch of my instrument ### 1/5 — Does not work *2023-09-29* App does not work. **Developer response:** Please try out the new version 3.0, it should work very well also on newer iOS versions ### 2/5 — No longer functional *2022-12-29* This was a nice and very useful app, but has died of bit rot and is apparently no longer supported. Developer, please consider open sourcing if you are not able to maintain it? It’s a nice piece of work and deserves better. **Developer response:** Thank you for your appreciation. I'm happy to tell you Well Tempered has been updated to 3.0 and should work very well. ### 1/5 — Have been using for years, now has bad feedback problem *2022-12-16* I loved this app for tuning my harpsichord, but it is now broken by some sort of feedback issue with the microphone. I would pay money for this if it were fixed. **Developer response:** Thank you for your feedback, the new version solves this issue, and you should be getting the upgrade for free through the App Store ### 1/5 — Not for iPhone or iPad *2020-07-14, version 2.1* This isn’t able to aces the microphone on my iPhone or iPad -shame as the idea is great ## Frequently asked questions about Well Tempered ### What is Well Tempered?
