Know when your period is coming

CareLync predicts your next period and fertile window based on your logged history — and gets more accurate the more you use it. No internet required.

🏥

Walk into your GP with your full cycle history

Generate a plain-text clinical summary of your cycle, symptoms, and medications in one tap. Give your doctor the context they need to help you.

🧘

See how your cycle affects how you feel

Log mood, energy, and sleep alongside physical symptoms. Over time, patterns emerge — so you can plan around your cycle, not against it.

🤰

Follow your pregnancy week by week

Switch to pregnancy mode and track your baby's development alongside your own physical changes through each trimester — all offline.

🔒

Your data lives only on your phone

CareLync has no server-side account. Your cycle and health data is stored locally and never transmitted to any platform, advertiser, or third party.

📊

Spot patterns you'd otherwise miss

Charts and timelines turn months of daily logs into a clear picture of your hormonal health — useful for conversations with your doctor or specialist.

Three Modes

Tracking that fits where you are right now

📅

Cycle Tracking

Log periods, predict your next cycle, and track how each phase affects your mood, energy, and sleep.

Identify your fertile window based on your own logged data — no guesswork, no subscription required.

🐣

Pregnancy

Follow weekly development milestones and track your own physical changes through all three trimesters.

CareLync is built offline-first. There are no accounts, no cloud sync, and no servers receiving your health data. Your cycle logs, symptom entries, and pregnancy records are stored only on your device. We have no way to access them — and neither does anyone else.
