Most period apps were built for adults trying to get pregnant. Calla wasn't. It's built for teens who just want to understand what's happening in their body - without the noise, the upsells, or the ovulation countdowns. Your data lives on your phone. No accounts required. No ads. No third parties, no data brokers, no advertisers. Optional parent share, if you want it. Privacy-first. Always. All your data stays on your phone. No accounts. No cloud. No ads. No data selling. Period. Built for how your body actually works Irregular cycles? That's normal, especially when you're starting out. Calla doesn't just assume a 28-day cycle - it learns your patterns and gives you predictions that actually make sense for your body. Track what matters to you Log your period, flow level, mood, energy, cramps, sleep, skin, focus, appetite, and activity. See how your cycle connects to how you feel day to day. Understand your cycle Get gentle, age-appropriate insights about each phase of your cycle - what's happening in your body and what to expect.
