About this app

Stay close to the people who matter — before life gets in the way.

Foster is a relationship tracker and check-in reminder app built for one simple truth: the friendships and family relationships we care about most are often the easiest to accidentally neglect. Foster helps you stay in touch with the people who matter, on your terms.

Never lose touch again
Add the people you want to stay connected with, set how often you'd like to check in — weekly, monthly, or on your own schedule — and let Foster send you a gentle reminder when it's time to reach out. No more realizing it's been six months since you last spoke to someone you love.

Your personal CRM for relationships
Think of Foster as a personal CRM for friends and family. Track check-in history, build streaks, and keep private notes on conversations, birthdays, or anything you want to remember about the people in your life — so every time you reconnect, you pick up right where you left off.

Smart conversation starters
Not sure what to talk about? Foster's brainstorm feature uses AI to suggest thoughtful conversation ideas based on the notes you've written — so reaching out never feels awkward or forced.

Built for privacy
Your notes and relationships are yours alone. Foster has no feeds, no followers, and no messaging between users — everything you write stays private to you. Import a contact using your phone's built-in picker (Foster never sees your full address book), or add someone manually in seconds.

Features:

Custom check-in reminders for every relationship
Private notes and check-in history
Streaks to track your consistency
Group your contacts (family, friends, etc.)
AI-powered conversation suggestions
Google & Apple Sign-In — no passwords to remember
Full data control — delete your account and data anytime

Whether you're rebuilding touch with old friends, staying close to family across the world, or just want a simple relationship reminder app that keeps you consistent — Foster is the stay-in-touch app built to help you show up for the people who matter.

Download Foster today and never let another important relationship fade into silence.
Never lose touch. Track check-ins, set reminders, and keep private notes.
