Log
Tap once to record sexual activity — with ejaculation, or without.
Male Sexual Energy
Track the energy you spend. Restore it on your own terms.
An iPhone app for men who want to manage vitality with one number, updated every minute.
Free to use. Premium is optional.
The signal
One number that tells you where you stand.
Every act of ejaculation drops your score to 0%. Time, age, and non-ejaculatory practice bring it back.
The math is simple, the consequences are not.
See how it's calculated
How it works
Three taps from logged to understood.
Calculate
The app updates your energy score minute by minute, based on your age and history.
Preserve
Get a recommendation tuned to where you are right now — not generic advice.
What you log
Two things to log. Nothing more.
Outflow
Activity with ejaculation. Score resets to 0%. Recovery begins.
Save
Activity without ejaculation. Score isn't reset, and a small bonus is applied.
Both kinds of activity sync to Apple Health, privately.
Roots
Built on a tradition that's been tested for centuries.
The math behind your score comes from Mantak Chia's “Taoist Secrets of Love: Cultivating Male Sexual Energy.”
This isn't a coaching opinion. It's a regulation principle that men have used for a long time.
Not medical advice. The app supports your awareness — it doesn't replace a clinician.

FAQ
Questions, asked honestly.
Is this app for me if I'm not into Taoism?
Yes. The Taoist origin is the source of the math — but using the app doesn't require any practice or belief. You log, you read your score, you decide.
Is this a NoFap app?
No. MSE is about regulation, not abstinence. The app accepts both ejaculation and non-ejaculation activity, and there's no streak to break.
Does it work for women?
No. The algorithm models male physiology specifically.
Is there an Android version?
No, and there are no current plans for one. We focused on iPhone, Watch, and Apple Health integration.
Will the free version always be free?
Yes. The tracker — logging activity, calculating your score, syncing to Health — stays free indefinitely. Premium adds statistics and content on top.
What does Apple Health share with the app?
With your permission, the app reads your date of birth (to calibrate the algorithm) and reads and writes sexual activity samples. Nothing else.
Is this medical advice?
No. MSE supports your awareness of your own patterns. It doesn't diagnose, treat, or replace a clinician.
