Side-by-side comparison
The criteria that matter most for early cycles.
What changes in practice
Age and starting point matter
Clue’s official guidance says users under 16 need a parent or guardian’s permission and help with privacy settings, while US users under 13 cannot use the app. Soso is built around the earlier first-period journey.
Privacy is not a zero-sum claim
Clue has a credible privacy position. Soso should win on age-appropriate simplicity and family context, not by making a vague privacy attack.
