BirthdayBridge

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.
