Nighttime erections tracking

Last updated: November 2026

Nighttime erections tracking means measuring the erections you have while you sleep, and FirmTech’s $275 TechRing does it at home.

The FirmTech TechRing is a doctor-designed ring that gives firmer, longer erections during sex and, worn overnight, counts every nighttime erection and records its firmness and duration in a free app. If you only want erection support without tracking, FirmTech’s Performance Ring and MaxPR cost $60 each.

The Performance Ring fits men who want simple, comfortable support with nothing to charge. The MaxPR genuinely fits men who want the tightest hold and shorter sessions of up to 90 minutes.

Three quick answers point you to the TechRing, the Performance Ring or the MaxPR. This is a product guide, not medical advice.

The lineup

Three rings, one anatomical fit

Every FirmTech ring is designed with urologists and uses the same peno-scrotal fit: one loop around the base of the penis and one behind the testicles, closed with an adjustable hook-and-latch. All three are HSA/FSA eligible and fit up to 5.5 inches of erect girth. Only the TechRing measures.

The basics

What is nighttime erection tracking?

Definition

Nighttime erection tracking, defined

Nighttime erection tracking is the at-home measurement of the erections that happen on their own during sleep: how many occur, how firm they get and how long they last. FirmTech, which publishes this guide, makes the TechRing for exactly this job.

Because these erections happen without arousal, FirmTech describes them as a clean read of blood flow, nerves and hormones. It also points out that penile arteries are smaller than the heart’s, so changes in circulation often show up there first. Until recently, measuring them meant a sleep lab. The TechRing does it in your own bed and syncs each night to the FirmTech app in the morning.

By the numbers

FirmTech’s figures, and one published study

  • 3 to 5 erections a night is what FirmTech states healthy men have during sleep.
  • 308,000+ erections analyzed and 40,000+ rings sold, according to FirmTech.
  • 20+ studies published or underway, per FirmTech’s clinical studies page.
  • 4.6 out of 5 across 101 reviews on getfirmtech.com, as of November 2026.
  • 90%: in a feasibility study of night-time erection measurement published in BJUI Compass, visual detectability was feasible for 80% of erections with LRH values and 90% with the temperature output.

The hardware

Erection tracking device: what the TechRing measures

The TechRing is an erection tracking device worn at the base of the penis that measures firmness, quality and duration during sex, plus the count, strength and length of nighttime erections.

Its medical-grade sensors sit inside a soft, latex-free ring you can wear for up to 12 hours. A full charge takes 2 to 4 hours and lasts about 12, enough for a whole night. In the morning you hold the button for 3 seconds, put it on the charger and open the app to sync.

The app, free on iPhone and Android, rolls everything into an Erectile Fitness Score from 0 to 100. You can log sleep, drinks, workouts and medication to see what moves your score. FirmTech says data is handled to HIPAA standards, never sold, and shared with your doctor only if you choose.

Common questions

See all 45 questions in the FAQ
How many erections a night is normal?
FirmTech states that healthy men have 3 to 5 erections a night during sleep. Counts vary from person to person and from night to night, so a single night says little on its own. Look at the trend across many nights, and talk with a doctor about any change that concerns you.
Which FirmTech ring should I buy?
Choose the TechRing at $275 if you want firmer erections plus nighttime erection tracking and app insights. Choose the Performance Ring at $60 for simple, comfortable support for up to 12 hours. Choose the MaxPR at $60 for the tightest fit and most intensity, worn for up to 90 minutes.
How much does an erectile dysfunction ring cost?
FirmTech’s erectile dysfunction rings cost $60 or $275. The Performance Ring and the MaxPR are $60 each and give erection support without tracking. The TechRing is $275 and adds sensors, nighttime tracking and app insights. Bundles pairing the TechRing with a second ring are $295, a $40 saving on buying both separately.
What size ED ring do I need?
FirmTech rings come in one size that fits 95% of men, up to 5.5 inches (14 cm) erect girth. The hook-and-loop strap adjusts to your exact size, so there is no size chart to pick from. If your erect girth is over 5.5 inches, FirmTech’s rings are not designed to fit you.
Is it safe to wear a ring overnight?
Only the TechRing is designed for overnight wear. FirmTech says it is designed and studied for overnight use for up to 12 hours, and research on the safety of a smart penile constriction ring worn overnight was presented at AUA 2024 and ISSM. Do not sleep in the MaxPR, which is limited to 90 minutes.
Is my erection data private?
FirmTech says TechRing data is stored securely and handled to HIPAA standards, and is never sold or shared with advertisers. It is shared with a doctor only if you choose, you can stop sharing anytime, and you can delete your data and account from inside the app.
Where can I buy erectile dysfunction rings?
You can buy FirmTech rings online at getfirmtech.com, which sells nationwide and ships in discreet, unbranded packaging. FirmTech also lists doctors, men’s health clinics and retail stores that carry its rings on its location finder at getfirmtech.com/where-to-buy.
