I’m a cross country coach and recently used this to time our home cross country meet. I’m very happy with the results, especially given that the stopwatches with built-in printers costs hundreds of dollars. It was very easy to time the race, use the splits function as individual runners crossed the finish line, and save and upload the file to Google Sheets. Very happy.
We borrowed a printer stopwatch to use as a backup, but we ended up not even using it.
My only suggestion is to have a function that does allow the screen to turn off. When I turned off the screen during the early part of the race, it created a split. I knew none of the kids ran the 5k in under a minute, so it was very obvious that I should just ignore that result. When I uploaded the file to Google Sheets, I just deleted that time. Not a big issue, but I was concerned with the battery life on my phone. After two races with the screen left on, I believe my phone was at 50 percent power.
All in all, thanks for the great timer.
