BirthdayBridge
Birthday reminders set to their time zone, not yours.
About BirthdayBridge
Calculates the exact moment to wish someone happy birthday based on global time zone overlaps. Rather than triggering standard midnight alerts, the algorithm scores availability slots during a contact's birthday to align their morning hours with the sender's awake schedule. Users organize contacts, configure notification preferences, and launch pre-filled greetings through messaging platforms directly from notifications while keeping all personal data stored locally.
Who is BirthdayBridge for?
Designed for people managing relationships across different countries and time zones. Before using it, users relied on basic calendar alerts that fired at midnight local time, resulting in messages arriving while international friends were asleep or long after their actual birthday had passed in their region.
How does BirthdayBridge work?
First, import contacts from the device address book and select each person's city or time zone. Next, pick a reminder mode such as the smart overlap engine, their morning, or a custom time. Finally, receive a time-zone-adjusted notification and tap to send a pre-filled message through iMessage or WhatsApp.
