BirthdayBridge

Time zones shouldn't get in the way of the people you care about. BirthdayBridge tells you exactly when they're awake, wherever they live.

Most birthday apps remind you at midnight in their timezone. BirthdayBridge calculates when the person is actually experiencing their birthday — and finds the perfect moment for you to reach out. Smart timezone-aware reminders — The Smart Window algorithm finds the optimal overlap between your waking hours and your contact's local time. You get notified at the right moment — not just when the calendar date changes. One-tap birthday messages — Send a pre-written birthday message via iMessage, WhatsApp, or Email directly from the notification or app. Personalise message templates with nicknames and custom greetings. Built around your contacts — Import from your address book or add contacts manually. BirthdayBridge reads names, birthdays, and addresses — nothing else. No data ever leaves your device. BirthdayBridge Premium — Unlock unlimited contacts, all reminder modes, home screen and lock screen widgets, and all eight colour themes with a single one-time purchase. No subscription. Ever. Your contacts. Your data. On your device.
