NFL Reporter Jane Slater Caught Her Boyfriend Cheating Via His Fitbit
On Twitter, she shared the story of catching her ex in the act when his Fitbit activity spiked at 4 a.m.

Gone are the days when you had to smell your spouse's shirts or dig through their car to catch them committing infidelity. Today, it's all about the apps. People are catching their partners cheating by sleuthing on Instagram, Twitter, and—according to one viral tweet—Fitbit. Yes, NFL reporter Jane Slater, 38, revealed she caught her ex-boyfriend cheating via Fitbit.
On Dec. 5th, Slater responded to the controversy surrounding the Peloton Christmas commercial by tweeting that one Christmas, her ex-boyfriend got her a Fitbit—which tracks the number of steps you walk, your sleep quality, your heart rate, and other indications of physical activity and overall health.
At first, she "loved it." The couple synced up their Fitbits so they could help each other stay motivated to work out. It was all going well… until "he was unaccounted for at 4 a.m. and his physical activity levels were spiking on the app."
An Ex Boyfriend once got me a Fitbit for Christmas. I loved it. We synched up, motivated each other… didn't hate it until he was unaccounted for at 4am and his physical activity levels were spiking on the app 🥴wish the story wasn't real. https://t.co/npRkLJYYz0

Slater's tweet went viral. Some people chimed in to say maybe he was just watching TV. Those cop shows can really raise your heart rate!

But it gets worse. Slater added that she was at his apartment with balloons because his birthday was the following day, and any activity at 4 a.m. was out of character for him.
Calling the police station bc I was at his home with balloons for his birthday and the behavior was out of character 😂

She's fairly certain he was not at a spin class.
Spoiler alert: he was not enrolled in an OrangeTheory class at 4am.

Plenty of people who'd been cheated on made jokes on Twitter about those so-called "activity levels."
Been there. Didn't find out though Fitbit though. My ex's physical activity would have only spiked for like 90 seconds so it would have been practically unnoticeable anyway.

And impressively, Slater is taking it all in stride now.
My girlfriend once said "one day we will laugh about this" as I sobbed uncontrollably in the car. I have now many times bahahahah
