An independent studio in Toronto building apps about the awkward parts of being around other people: who owes who, and who to spend an evening with.
Split expenses fairly, not just evenly.
Shared costs for couples, housemates and friends. It is the only app of its kind that can divide a bill in proportion to what each person earns, which matters when an even split quietly costs the lower earner twice as much of their income.
Post a plan. Leave one seat open.
Meeting someone new around something you were already going to do. You post a real, time-boxed plan at a public venue with one seat free, people ask for the seat and say why, you pick one, and the chat opens only once the seat is locked.
Independent and deliberately small, so every decision is made by someone who will also have to support it.
Halvy collects no usage analytics and asks for no bank connection. It is a constraint we design around, not a setting.
Halvy has been live on both stores since July 2026 and has been updated steadily since. Seatt is called pre-launch here because it is.
