About this app

Keep the people who matter from quietly drifting away.

Life gets busy and the friendships you care about slip, not from a falling out, just from time. Foster is the quiet layer of care over your real life. It keeps the people who matter close and gives you a gentle nudge before a relationship goes cold. It is not a social network, not a feed, not a replacement for your contacts. It is a private place to be intentional about the people in your life.

You decide who belongs and how often you want to be in touch. Foster watches the rhythm and tells you who is due, so staying close becomes a habit instead of an afterthought.

FIVE TABS, ONE QUIET SYSTEM
- People: everyone you choose to keep close, each with the cadence you set and a health read that shows at a glance who you have drifted from.
- Today: who is due for a hello, plus the follow-ups you promised, so you always know the one small thing worth doing now.
- Moments: the calls, messages, meetups and milestones worth remembering, logged in a tap so the history of a friendship is yours to keep.
- Occasions: birthdays and the dates that matter, surfaced early enough to actually act on, never the morning of.
- Pulse: how your circle is doing as a whole, who is thriving and who is slipping, with honest empty states instead of invented trends.

THE FREE VERSION IS A REAL TOOL
Keep up to twenty people, log moments, set your cadence and get nudged, with no ads, ever. Free is a working relationship tracker, not a teaser.

FOSTER PRO adds the deeper layer:
- Keep an unlimited circle
- A catch-up brief that pulls together what matters before you reach out
- Suggested openers tuned to each person and moment
- Thoughtful gift ideas you can save per person
- Voice-note logging for moments on the go
- Editable cadence defaults across your whole circle

PRIVATE BY DESIGN
Everyone you add and every moment you log stays on your device. No account, no sign-in, no server, nothing uploaded. Foster never reads or imports your phone's address book; you choose exactly who to add.

Foster is a personal tool for being a better friend, not a productivity CRM and not a place to perform. The people are real. Keep them close.
