Build your sobriety record, day after day.
Turn each BAC reading into a dated, tamper-evident record. Build a clear picture of consistency a lawyer, mediator, program, or family member can review with the right context—using your own breathalyzer and your own phone.
Your reading. Your timeline. Honest limits.

What Notarus proves — and what it does not
Notarus does not watch you take a test. It preserves when your self-recorded reading was saved and whether the record has changed since. Gaps remain visible. If a court or program requires a particular testing service, follow that requirement.
