Compare before choosing
Every page shows where Soso fits best鈥攁nd when the competitor may be the right choice.
VSvs. Flo
A first-period app or a platform for the whole reproductive-health journey?
Both track cycles, but they serve different moments. Soso is built around first periods and early cycles; Flo covers a much broader reproductive-health journey, from the first period through perimenopause.
VSvs. Clue
A gentle first-cycle start or deep science for every stage?
Clue combines science-led tracking with strong European privacy positioning. Soso focuses the experience on puberty, first periods, and a language families can use without extra setup.
VSvs. Period Calendar
A focused first-period experience or a free calendar packed with features?
Period Calendar offers broad tracking, strong distribution, and anonymous use. Soso trades feature volume for a quieter, age-appropriate first-period experience without ads.
VSvs. My Calendar
An app built around the first period or a broad tracker with a Simple Mode?
My Calendar offers deep customization and a Simple Mode that hides fertility data. In Soso, age-appropriate context is the product foundation, not a setting families must configure.
Age appropriate
First-period context matters more than a huge feature list.
