Track hours automatically. Improve working conditions. Open Working Hours helps healthcare workers document actual working hours easily โ and make structural problems visible. Overwork in healthcare is well known, but rarely documented. Without independent data, there's no foundation for change. Open Working Hours gives you a private record of your hours, and lets you contribute anonymously to aggregated statistics that show what working conditions actually look like across hospitals and specialties. Tracking shouldn't be an additional burden. Automatic clock-in/out via geofencing as you arrive at and leave your workplace, or log shifts manually in seconds with reusable templates. Built for hospital life: fast, reliable, low-friction. Creates transparency Plan your shifts, track what actually happens, see overtime at a glance over 14 days. When you choose to contribute a confirmed week, it joins anonymized, aggregated statistics at the institutional level โ turning isolated experience into a shared picture of working conditions. Privacy from the start Daily shift detail, your calendar, and location data stay on your device. Geofencing detection runs locally. Optional workplace search uses Photon (Komoot, Germany). Only aggregated statistics are ever published, and only when at least 5 people contribute to the same group (k-anonymity), with additional statistical noise to protect against re-identification. No employer access. EU-only infrastructure for hosting, email, and geocoding โ optional Apple/Google sign-in is the only US touchpoint, under EU adequacy. No analytics SDKs. No advertising. No third-party trackers. GDPR compliant. Delete your data anytime. For healthcare workers Designed with and for doctors, nurses, midwives, and other healthcare workers. Use it solo from day one โ your contributions become statistically meaningful as more colleagues join. Free. Non-commercial. Learn more: openworkinghours.org
