Travel and travel-adjacent
The studio's focus is tools for trips — planning them, paying for them, and dealing with what happens when they do not go to plan.
Apps
What we ship.
Every app we publish is developed in-house by Last Layover LLC and released under the studio's name.
Untilt
Bill splitting for iOS and Android · Free · No account required
Untilt splits shared expenses between a group of people without asking anyone to make an account. You create a group, share a link or QR code, and everyone adds what they spent. It works with no connection at all, and syncs through a relay that only ever handles encrypted data.
What it does
- No account, ever. No email, no phone number, no password. A group lives behind a private link you share with the people in it.
- Fully offline. Add and edit expenses with no signal; changes queue on the device and upload themselves when you reconnect.
- End-to-end encrypted sync. The encryption key travels in the fragment of the invite link, which browsers never send to a server. The relay stores ciphertext it cannot read.
- Any currency. Enter an amount in the currency you actually paid in. Untilt converts to the group's home currency at a rate you can edit, including historical rates for past dates, and freezes it so old expenses never drift.
- Four ways to split. Equally, by exact amounts, by shares, or itemized straight off a receipt — with support for more than one payer on a single expense.
- Balances and settle-up. See who owes whom, either simplified into the fewest transfers or in full, then record the settlements.
Built for trips
- Receipts. Attach a photo and itemize from it, so a shared dinner splits line by line instead of down the middle.
- Multiple groups. A trip, a flat, and a recurring dinner can run side by side without mixing.
- Comments and history. Every expense can be discussed, edited, or deleted, and the group sees what changed.
- Categories. Tag expenses so it is clear afterward where the money actually went.
- Multilingual. Localized, because the people on a trip are not always from the same place.
What we are working on
Untilt is the first of a set of apps aimed at the same problem from different angles: the practical friction of being away from home.
The same constraints
Anything new we ship holds the line on the three rules: private by default, useful with no connection, and small enough to actually finish.
Built here
Design and engineering both happen in-house. We are not reselling or white-labeling someone else's software.
