AsterKit

Private Period & Cycle Tracker

Only for iPhone

Free · In‑App Purchases

iPhone

Track your cycle privately. Zero data collection, zero accounts, zero analytics. AsterKit is a privacy-first period tracker for ages 13+. There are no accounts and no login — all data stays on the device. To reach premium features: on first launch, the parental gate shows a math problem (e.g., "14 + 27 = ?") — type the numeric answer to proceed. The 7-day free trial then starts automatically (no payment required) and unlocks all features including Advanced Insights and PDF export. Tapping a locked premium feature re-shows the parental gate before the purchase sheet. No demo account is needed.
