### 5/5 — Great App with adjustable ms offset!

*2026-08-08*

Love the offset option!!
As s possible enhancement, would love if you added an optional audible 5 second count down  at the hour i.e. (beep-beep-beep-beep-beep-boop).

**Developer response:** Thank you for the wonderful review and for loving the offset option! The audible countdown is a great suggestion, and I'll make sure to take note of it for future update considerations. Thanks for your support!

### 1/5 — No option to remove intrusive ads!

*2025-10-26*

There are ads and there are intrusive ads.  This is very much in the latter camp.  Ads play for several minutes before you get an option to skip making the app an unusable joke!
Why not provide an option to buy without ads???

**Developer response:** Sorry for the bad experience, and thank you for the honest feedback.
I agree—ads that take minutes to skip are intrusive and not acceptable. I’m tightening the filtering and blocking settings in the ad network to reduce these kinds of aggressive ads as much as possible.

Regarding a one-time “Remove Ads” option: at the moment, I’m not able to offer it due to current eligibility/administrative requirements. If it becomes possible in the future, I’ll seriously consider adding it.

### 5/5 — Exactly what I needed

*2025-09-19*

I’m running some experiments and wanted to have the exact time on video. This worked perfectly. The combination of elapsed time and absolute time is perfect too.

**Developer response:** I'm so glad the app was helpful with your experiments. Knowing how the app is used in the real world is excellent feedback that directly guides our improvements. Thank you! Please don't hesitate to reach out if you have any further suggestions or need enhancements.

### 5/5 — Nice but add widget
