Supasplit vs Kittysplit — which one fits your group?

Supasplit is an ongoing splitting app for friend groups and roommates. Kittysplit is a zero-friction tool for a single event. Different use cases, both valid. If your group just needs to settle a weekend trip and no one wants to download an app, Kittysplit is hard to beat. If you're tracking shared life across months and years, Supasplit is built for that.

Frequently asked questions

Is Kittysplit still a good choice in 2026?

For one-off events, yes. If your group is booking a weekend cabin and no one wants to install an app, Kittysplit's shareable link flow is genuinely hard to beat. Where it falls short is ongoing life: roommates, couples, or friend groups who split things every week will hit the no-persistent-balances wall pretty fast.

How is Kittysplit different from Supasplit?

Kittysplit is event-based and browser-only. You create a kitty for a trip, share the link, and settle up when it's over. Supasplit is relationship-based and iOS-native. You create groups that last, and balances carry across every dinner, grocery run, and trip. Different shapes, different jobs.

Can I use Kittysplit for roommate expenses?

You can, but it's awkward. Every kitty is a fresh event with no memory of the last one, so you'd either run one enormous ongoing kitty forever or rebuild a new one each month. Most roommates end up moving to a group-based app like Supasplit for this reason.

Does Kittysplit have a mobile app?

No. Kittysplit is web only. It works in a mobile browser, but there's no iOS or Android app, no widget, no push notifications, and no offline support. If you want a real app experience, you'll want Supasplit or Splitwise instead.

Can I import my Kittysplit history into Supasplit?

There's no automatic import. The cleanest path is to export the kitty as CSV for your records, settle up that event in Kittysplit, and then start fresh groups in Supasplit. Since Kittysplit doesn't carry balances between events anyway, you're not really leaving anything behind.

Do I have to pay for Kittysplit or Supasplit?

Kittysplit is free forever with no paid tier. Supasplit has a free tier that covers up to 3 groups, all 120+ currencies, all split methods, smart reminders, and no ads. Supasplit Plus is $3.99/month for unlimited groups, unlimited AI scans, voice entry, themes, custom icons, and the iOS widget.
