EveSync: a calmer period and ovulation tracker that stays on your phone

EveSync by Knox Studios combines period tracking, fertile-day estimates, BBT charts, pregnancy-week notes, and pill-pack logging in a quiet, on-device cycle app — without a loud social feed.

Key takeaways

EveSync is a period and ovulation calendar with BBT logging and pregnancy-week education.
Predictions start from cycle settings and sharpen after three completed cycles.
Cycle logs are designed to stay on device; no mandatory account.
Premium unlocks ad-free tracking, deeper Insights, Learn, exports, and pill reminder notifications.

Cycle tracking without the mall energy

Most period apps interrupt a simple log with streaks, feeds, and paywalls. EveSync by Knox Studios is built for the jobs people actually open a cycle app for: when period is likely, which days look fertile, how mood and energy line up, pregnancy week notes, and whether you took your pill.

What EveSync includes

Today week strip, cycle status, and one-tap Log
Calendar colors for period and fertile stretches
Body tab for waking basal temperature (BBT) with confound tags
Pregnancy mode with clinician-first week notes from LMP or due date
Pill-pack logging (push reminders with Premium)

Fertile-window estimates are educational — not contraception. Your clinician’s guidance always comes first.

Private by design

Cycle and symptom logs are designed to stay on this device. This release does not sync wearables or Health Connect. Free tracking includes ads; EveSync Premium removes ads and unlocks Insights depth, Learn, exports, and pill reminder notifications.
