K193330 is an FDA 510(k) clearance for the Clue Birth Control. Classified as Device, Fertility Diagnostic, Contraceptive, Software Application (product code PYT), Class II - Special Controls.

Submitted by Biowink GmbH (Berlin, DE). The FDA issued a Cleared decision on February 18, 2021 after a review of 444 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Obstetrics & Gynecology FDA review panel, regulated under 21 CFR 884.5370 - the FDA obstetrics and gynecology device framework. The Abbreviated 510(k) pathway was used, relying on FDA-recognized standards to demonstrate substantial equivalence.

Device pattern: High-complexity regulatory submission. Standards-verified equivalence. The extended review timeline suggests the FDA required additional documentation before confirming substantial equivalence - a pattern common in complex or first-of-kind Obstetrics & Gynecology submissions.
