A revolutionary new smartphone application is demonstrating remarkable success in helping men extend their bedroom performance, not through traditional techniques, but by strategically replaying their former partners' most cutting criticisms regarding their sexual prowess.

Developed by 'Cognitive Performance Solutions Inc.' and dubbed 'The Inner Critic Pro,' the app reportedly syncs with users' old social media posts and text messages, selectively surfacing negative feedback at critical moments. A randomized trial published this week showed participants using the app experienced a significant increase in duration, with many attributing the improvement to a sudden, overwhelming urge to prove someone wrong.

“We found that while physical techniques have their place, nothing motivates a man quite like the phantom echo of a past lover’s disappointment,” explained Dr. Evelyn Thorne, lead researcher. “The app doesn’t teach; it reminds. It’s less about mindfulness and more about mind-shame.”

One trial participant, Chad Peterson, 38, reported a 300% increase in stamina. “I just hear my ex-girlfriend, Brenda, saying, ‘Are you done already?’ in my head, and suddenly I’m capable of feats I never imagined,” Peterson stated, visibly sweating. “It’s like a personal trainer, but for your ego.”

Critics argue the app might foster unhealthy psychological patterns, but developers insist the results speak for themselves. The company is now exploring a premium version that includes AI-generated hypothetical criticisms from current partners, just in case the user’s past isn’t sufficiently scarring.
