Sentinel tracks what you actually feel — energy, focus, balance — so patterns stop being invisible.
iOS first. Launching Q2 2026.
Every mental health app was built for someone else.
Journals. Affirmations. "Breathe in for 4 counts." 🌸
You deleted it after day two.
Not because you don't care about your head.
Because the product didn't respect your intelligence.
60 seconds. Every day.
Three sliders. One optional note. Done.
After two weeks, the data talks:
"Your Mondays run 23% below your baseline."
"You recover in 2 days after high-stress events."
"Your best weeks start with consistent Thursdays."
You can't guard what you can't see. Sentinel shows you.
How much fuel do you have today?
Can you lock in when it matters?
Are you operating steady or on the edge?
Built for men who already track their lifts, their sleep, their macros —
and know their mind deserves the same rigor.
No therapy-speak. No journaling prompts. No passive affirmations.
Just data, patterns, and clarity.
Your mind. Your watch.
"Finally an app that speaks my language."
