The Logic of You

Using a series of Probabilistic & Adaptive engines, ULA learns your unique cycle, making accommodations for irregularities like PCOS or PMS.

Complete Sovereignty

Data is stored entirely on-device. Export, import, or erase your entire history with one click. No cloud, no leaks.

Deep Symptom Logging

From Mittelschmerz to mood swings, track exactly how you feel at every stage of your cycle.

Your body. Your data.

ULA was built because your most sensitive information shouldn't be a product. Your data stays on your device, we don't collect, track it or analyze it.

Everything happens on your device.
