Millisecond Clock2.4.0 - App Store
You'll be able to see results in few seconds.
Publisher Description
Millisecond Clock shows the exact time down to 1/1000 of a second, accurate enough to measure real delay in cameras, video streams, and network connections.
Point a camera at the screen and compare it to another display: the difference in milliseconds tells you exactly how much latency you are dealing with.
Beyond precision, Millisecond Clock is a clock you can make your own. Every part of it, from color and font to position on screen, is yours to design.
DESIGN YOUR CLOCK- 13 built-in color themes, or create unlimited custom themes with the full color picker
- 30 fonts, from the classic digital LED look to elegant serif and rounded styles
- Adjustable glow and shadow effects for extra depth
- Drag the clock, date, and weekday anywhere on screen, and resize each one independently
STAY ON TIME, YOUR WAY- 12-hour or 24-hour time, with an optional blinking colon
- 9 date formats to match how you write dates
- Show or hide the date and day of the week
- Toggle the millisecond display on or off
BUILT TO STAY ON SCREEN- Keeps your screen awake so the clock is always visible
- A true universal app, designed for both iPhone and iPad
Millisecond Clock is free to use, supported by ads.
A one-time in-app purchase removes ads and unlocks every premium theme, no subscription required.
Version History - Resizing the time, date, and weekday on the main screen now works correctly, and your adjustments are saved.
- "Reset Settings" no longer removes your purchases. Remove Ads and Unlock Themes stay active after a reset.
- Color picker: the red, green, and blue sliders now respond reliably, and adjusting one channel no longer moves the others. Short hex codes (such as #FFF) are now supported.
- The preview clock in Settings now follows your 12- or 24-hour preference and correctly shows 12 (instead of 00) at noon and midnight.
- Fixed a case where the loading indicator could stay on screen after a purchase or restore didn't finish; purchases and restores are now more reliable.
- General stability improvements and fixes for several rare crashes. 2.4.0 Sep 3 - Reduced battery and GPU usage from the clock's glowing digit effect, especially during long display sessions.
- Fixed a bug where the ad banner could duplicate and use extra memory when returning to the main screen.
- Smoother scrolling in the Themes and Date Format selection screens.
- Updated the advertising SDK to the latest version for improved reliability.
- General performance and stability improvements to the clock display.
- Reduced unnecessary background processing for better overall efficiency. 2.3.0 Aug 19 - Bug fixes and performance improvements. 2.2.0 03/04/2024 - Minor bug fixes and other small improvements. 2.1.0 09/18/2023 - Minor bug fixes and other small improvements. 2.0.1 08/29/2020 2.0.0 08/27/2020
