The first phone case

from your phone

Set your limit. Third Rail Case tracks every pickup. Go over it, get zapped.

How it works

One rule. Three rails.

1

Set your limit

Decide how many pickups you get a day.

2

It keeps score

Every pickup gets counted, automatically. Your running total lives on your home screen, all day.

3

Go over, get zapped

Approach the limit, the case vibrates as a warning. Exceed it, you get zapped.

Under the hood: a companion app sets your limit and keeps score; NFC confirms the case is on your phone; BLE and a thin battery fire the module. The zap is strictly opt-in. Full safety spec below.

Safety spec

Drive mode

Zap hard-disables when driving is detected via motion sensors, GPS speed, and car Bluetooth. Passenger override included. Pickups behind the wheel still log as danger pickups.

Output

TENS-level maximum, enforced by a hardware current-limit circuit, not software alone.

Rate

Zap-rate lockout: capped per hour, auto-suspends after repeated triggers.

Default

Ships in vibrate mode. The zap requires explicit opt-in and a self-calibrated intensity ramp.

Screening

18+ only. Onboarding screens for pacemakers, epilepsy, and pregnancy. Nickel-free contacts.

Not a medical device. Zap responsibly.

Limited first run

Get zapped first.
