A guardrail, not a green light
Foresight without false reassurance.
NightPace cannot make alcohol harmless or determine a safe amount. It deliberately forecasts conservatively, marks uncertainty and brings water, pauses and a safe journey home to the foreground.
Peak before logging
Before selecting a drink, see the maximum estimate it is projected to produce.
Conservative forecast
The trajectory shows a cautious estimate with a trend and uncertainty range — not just one number.
Custom and found drinks
Add, edit and delete custom drinks. An optional online search can use product details as a starting point.
Breath value adjustment
Optional breath-test values can adjust the future trajectory. This still does not turn the app into a measuring device.
Private history
Review peaks, trajectories, drinks, water and meals. Core data is processed locally on the device.
Designed for real evenings
Less calculation. More context.
Tap a point on the curve, preview the impact of the next drink and use the trend arrow to see where the estimate is moving. NightPace refreshes the view immediately after changes.

Buy once. Keep using it.
After 14 free days, NightPace can be unlocked permanently with a one-time €2.99 in-app purchase. Purchases can be restored through Apple. No subscription.
Important safety notice
No calculated value proves safety or fitness to drive.
NightPace is a private forecasting tool, not a medical device. Calculated values are model estimates, not measurements, medical advice or legal advice. A breath-test value may also be inaccurate.
Even small amounts of alcohol can impair reaction time, perception, judgement and coordination. After drinking, do not drive a car, motorbike, bicycle, e-scooter, skateboard or boat, and do not swim or engage in other risky activities. If you drive, stay at 0.00.
Alcohol harms health; NightPace cannot determine a risk-free amount. Less alcohol means less risk. If alcohol poisoning is suspected, symptoms matter more than any app value: do not leave the person alone and call 112 immediately.
When alcohol becomes a problem
Confidential professional support is available. In Germany, the DHS directory lists local counselling services; call 112 in an emergency.
