Veya vs Clue
Clue and Veya both take a calm, evidence-led approach to cycle tracking. The biggest differences are accounts, where your data lives, and what is free.
Clue is made by BioWink GmbH in Berlin. It has a free version and an optional subscription, Clue Plus, and offers modes for period tracking, trying to conceive, pregnancy and perimenopause. Its data is stored on servers in the EU.1,2,3,4
Veya hasn’t launched yet. Its side of this page describes what is planned for launch.
