Aeterna: Longevity Tracker

Record four daily habits with a manual check-in and save your daily vitality log. Review past entries and vitality statistics in the Archive. Set up your profile, enter your age and save personal targets. Personal targets do not change the fixed thresholds and weights used by the daily score. Explore two separate estimates: a daily age estimate derived from your habit score, and a PhenoAge estimate calculated from nine biomarkers you enter yourself. Switch biomarker units and preview the calculation in the lab screen. These estimates are for information only and do not show your exact biological age. Aeterna is not a medical device and does not replace a doctor. Daily habit logging, scores, history, your profile and biomarker previews are available without Pro access. Saving biomarker records and exporting daily logs as JSON require Pro access. The JSON export includes daily vitality logs only. It does not include your biomarker records or profile, and there is no import feature. Purchases use Google Play Billing. You can copy a daily summary to the clipboard and choose a light or dark theme.
