NanoSplit – Split Expenses
No account. No password.
Only for iPhone
Free
iPhone
Flat share, trip, festival: enter what was spent and NanoSplit says who owes whom. Invite by QR code – no account with us, no password, no ads.
NanoSplit splits expenses in a group – for flat shares, trips, festivals or family. No account with us, no password, no ads.
THAT SIMPLE
• Create a group, enter the names – done.
• Invite the others by QR code or link. Joining is one tap.
• Enter expenses: split equally, by shares or with fixed amounts.
• NanoSplit works out who owes whom – in few payments.
• Money changed hands? Tap the line, settled.
NO ACCOUNT WITH US
No registration, no e-mail address, no password. The app takes your name from your Apple ID with one tap – or you type it yourself. Whoever has the invitation link is in.
NEW IPHONE? NOTHING TO DO
Your groups belong to your Apple ID and are simply back on a new iPhone.
PRIVATE
What you enter is encrypted on the iPhone before it leaves the device. Only the members of the group hold the key. No tracking, no analytics, no ads.
WORKS OFFLINE
You can always add entries. As soon as there is a connection, the group's iPhones catch up with each other.
ALSO
• Your name is yours: it is tied to your iCloud account, nobody else can go by it in the group
• Every expense shows who entered it
• A notification when someone adds something
• Add people who don't have the app yet
• Save the current state as a PDF
• Several groups, each in its own currency
• Dissolve a group for everyone once it is no longer needed
NanoSplit syncs through iCloud; the iPhone has to be signed in to iCloud for that.
NanoSplit is a private, ad-free and experimental project.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
A new look. NanoSplit has become clearer and calmer: navy instead of black, one gradient for what matters, and every balance carries its colour and its sign.
• Follows your iPhone: light and dark, and the text size from Settings up to the largest step.
• New icon.
• Remove a member with a touch and hold on the name.
