15 minute timer, beeps every interval

Not exactly philosophy (off the beaten path for my channel), but these timers improve my quality of life (for work, especially) and I think it is imperative that I share them with you. It is the morally right thing to do. Even if it wrecks my KZbin channel algorithm.
Timer set to a 15 minute intervals for 10 repetitions, beeping at the end of each cycle. Total of 2 hr and 30 min (10 sets x 15 minute = 150 minutes). Think egg timer or pomodoro timer.
Perfect for completing repetitive tasks on time. Beep reorients attention to keep in focus, and helps reduce day-dreaming and distractions. My recommendation: turn headphones/speakers up in general, turn this video up, but turn all other apps down. For example, if you have lo fi hip hop playing in one tab, make sure the sound on this video is higher, so the beeps are heard over the music.
Have an interval time you want but can't find? Message me and I'll see if I can make one. Personally, I often use intervals that aren't at the 5 min increment, so if you request an unusual integer that is my jam.
If you use it and like it, let me know. If you think there are mistakes or improvements to be made, please let me know. If you want to distribute it, please credit me.

This video has been incredibly useful for keeping me focused when studying or doing... Pretty much anything where I should be regularly reminding myself of how much time has passed. Knowing how much time you're spending on a class's readings or having something to notify you that you may be hyperfixating on a topic has helped my pacing and retention so thanks

these timers are a little slow and over time these differences accumulate

It is subtle, but it looks like you're right. It should be shorter, in that for each minute it is really close to 61 seconds. Multiply that by 150 minutes, that gives you a couple minutes accumulated. I chalked this up to the extra beeps and initial read countdown, but it is somehow a little more than that.
