Amazing app
Update: the dev just replied to me and explained the hidden Hmm feature I was not aware of: taping the play/pause button let you edit specific time! Killer feature indeed, which let me preview upcoming LST in local time!
This app is wonderful to have: works on all devices (works on Mac as well as widgets which is all I need)
Clean, modern and easy to use
It’s free!
I’m so grateful
Exceptional and multifunctional
One suggestion for the developer: a user setting to allow the app to override the lock screen timeout optionally for a constant on display setting. Thank you for bringing this very useful app to the iOS environment.
Response from developer
Thank you for the comment. In version 9.1, an option to prevent the device from auto-locking (sleeping) was added. I hope it helps.
Almost; but, not quite.
Hope the developer takes this under advisement.
14 December 2024 UPDATE: Tsuyoshi Sawada quickly responded with a note through the Apple App store that he added an optional setting to switch on or off the JD/MJD in his LSTClock and I tested it this evening when making my observations. It is a perfect solution to a long term issue that I have struggled with in my work having to look things up and compute JD and MJD with online calculators. Tsuyoshi, your solution is perfect! Thank you for responding so quickly and as promised, your app is not rated ⭐️⭐️⭐️⭐️⭐️ and more. Thank you so very much!
Response from developer
Thank you for the suggestion, I added an option to show JD/MJD in version 8.3.

Widget broken
Extreme minimalism
“Local” sidereal time
Small bugs but unique in function
No Night Mode
Response from developer
Thank you for the feedback. Night mode is added in version 3.5 (I hope it helps).
