For nuclear families, blended families, single parents, and co-parents who don't live together. Whatever shape yours takes, Tavvi keeps you coordinated.
Family software usually solves abstract problems. We built Tavvi for the specific ones.
The kids transfer to Mom's. Both parents tap to confirm — the schedule update flows to everyone's phones, and there's a quiet record you can pull up later.
Dad pays $84 at the dentist. Tavvi splits it 70/30 according to the rule you set, posts it to the running balance with the ex, and the receipt lives next to the kid's name.
Step-kids' soccer game at 11. The toddler's nap at 1. Aunt-and-uncle dinner at 5. One calendar, every kid, the whole household — without rebuilding it on three different apps.
Most family apps assume one shape: two parents in one house. Real families look like everything from a single parent and one kid to a blended household with two exes and four children from three different relationships.
Tavvi treats the family as the unit, not the individual. You can be in more than one family. You can co-parent with more than one person. The calendar, the expenses, and the messages know which relationship they belong to — and never get them confused.
We'd rather do a small set of things carefully than a long list of things half-built.
Events, RSVPs, recurring schedules, and a custody overlay if you have one.
Set split percentages by category. The math runs itself; the receipts live with the kids.
Conversation, attachments, and emoji reactions. Pin the messages that matter.
Running balance between co-parents. Settle up via Venmo, Zelle, or cash — confirmed both sides.
Upload a custody decree and our AI extracts the schedule, support, and expense rules. You review before anything is saved.
Per-child albums and private notes. Milestones, behavior patterns, the moments worth keeping.
Two parents, shared kids, one household. Everything in one place — no co-parent UI cluttering up your day.
Current spouse, kids from prior relationships, one or more exes you still coordinate with. Tavvi is the only tool that handles this cleanly.
Two homes, one calendar, shared expenses. Custody schedule, handoff confirmations, settlement history — without the friction.
Just you and the kids. Calendar, expenses, photos, and the diary you've been meaning to keep. Nothing extra.
The free tier covers calendar, messaging, and basic expense tracking — enough for a lot of families.
Tavvi is built by Topaz Software — a small team that thinks family software should feel less like software. We started with co-parents, expanded to families of every shape, and we're shipping carefully so we get it right.
