Changelog

Everything new in Deudin, newest first. We ship often — check back to see what changed.

26.9.1901Latest

Invites that always finish

Accepting an invite could leave you in a group without a spot in it. That's fixed, and anyone already stuck gets their spot the next time they open the group.

Fixed
  • If your connection dropped or your phone suspended the app while accepting an invite, the group showed up in your list but you couldn't add transactions and the owner saw you as not joined. Your spot now completes automatically when you open the group.
  • Reopening an invite link you already accepted no longer says it's unavailable — it takes you straight into the group.
  • If the spot an invite gave you was later removed or taken, the group now tells you so instead of silently hiding the add button.
26.7.2103

Find it, filter it, read it

More of your feedback, shipped: search and filter your transactions, see who's in a group, and a few numbers that are easier to read.

New
  • Search your transactions by text and filter them by category, right from the transactions list.
  • Everyone in a group can now see the full member list in Settings — not just the owner. (Only owners can invite or remove people.)
Improved
  • Amounts now follow your device's language for the decimal and thousands marks as you type — so if your keyboard's decimal key is a comma, typing 9,89 just works.
Fixed
  • Changing a transaction's date now sticks after you save — it no longer snapped back to the original date.
  • The daily spend chart no longer overlaps its labels: amounts now show as short, readable figures like 1.2k, 100k or 1.2M.
26.7.2102

A calmer update

When a new version of Deudin is published, the page no longer reloads out from under you. You get a brief animated screen while the update is applied.

Improved
  • Updates no longer interrupt you mid-tap: when a new version is ready, a short animated screen appears while it's applied, then the app reopens on the latest version.
26.7.2101

A polished public face — now in two languages

The marketing site reads as one piece now: a consistent header everywhere, a clearer language switcher, a fully bilingual changelog, and proper Terms and Privacy pages.

New
  • Terms of Service and Privacy Policy pages, in English and Spanish, linked from the footer of every public page.
  • This changelog now speaks both English and Spanish — read it at /changelog or /es/changelog, each with its own Atom feed.
Improved
  • The landing page now uses the same header as the blog and the rest of the site, so the navigation feels consistent wherever you are.
  • The language switcher marks the language you're reading with a clear check, so it's obvious which one is active.
  • A Light / Dark / System theme switcher now lives in the header of the landing and every public page, not just your profile.
26.7.2001

Your data, in and out

Owners can now export a group's whole history to a CSV and import it back — a real backup you control, and a clean way to move a group between accounts.

New
  • Export transactions: owners can download every expense and payment in a group as a CSV, named after the group, its transaction count, and the date and time. Nothing is lost — every payer and every share is written out exactly.
  • Import from CSV: bring that same file back into any group, matching the people in it to members here — the same guided flow as the Splitwise import. It restores the ledger to the cent.
26.7.1901

Your feedback, shipped

A round of changes straight from your feedback: a light theme, clearer balances, and a few rough edges smoothed over.

New
  • A light theme that follows your phone's system setting automatically — plus a Light / Dark / System switch in your profile if you'd rather pick.
  • A “Today” shortcut on the date picker, to jump back to today in one tap after browsing other dates.
  • When you split an expense by exact amounts or percentages, you now see how much is still left to distribute as you type.
Improved
  • Balances read at a glance now: what you owe shows in red, what you're owed in green.
  • The who-owes-whom list leads with the biggest debt, so it's clear who could cover the next expense to keep things even.
  • The daily spend chart shows the actual amounts, not just bars — readable on your phone, no hovering required.
Fixed
  • Your notification settings no longer flicker and reload every time you reopen Settings.
26.7.1802

Deudin, discoverable

A whole public face so people can actually find Deudin: honest comparisons, practical guides, a free split calculator — and this changelog you're reading.

New
  • This changelog, plus an Atom feed at /changelog.xml so you can subscribe to releases.
  • Honest comparison pages against Splitwise, Tricount, Settle Up and Splid — including a step-by-step guide for migrating your Splitwise groups.
  • A public who-owes-whom calculator: paste who paid what, get the fewest transfers that settle everyone. Free, no signup.
  • Guides on splitting trip expenses, uneven rent, and multi-currency trips — in English and Spanish.
Improved
  • The landing now shows the free Stats features and answers more questions, and every public page is served as real HTML so search engines and AI assistants can read it.
26.7.1801

Ready for the beta crew

A focused pass on the rough edges you flagged: cleaner drawers, correct balances, and settings that only show what you can actually change.

Improved
  • The Activity tab is now reserved for group owners, so the feed stays useful for the people who manage the group.
  • Consistent wording across settle-up: it's "Settle" everywhere now, and the payment button says "Record" instead of "Save".
  • Adding a member you removed no longer leaves a ghost of them hanging around in pickers.
Fixed
  • Balances and currency labels now stay correct after you edit or delete an entry.
  • The currency dropdown on payments is properly aligned and actually selectable.
  • The "Paid by" menu behaves even when you haven't typed an amount yet.
  • Squashed a batch of beta-blocking bugs across drawers, balances, and labels.
26.7.1601

Currencies, your way

Every group is different — some are strictly one currency, others juggle three on a single trip. Now the owner decides which ones show up.

New
  • Owners can curate the exact set of currencies a group offers, so the picker is a short, relevant list instead of the full ISO catalog.
  • New groups start with USD and let the owner add more from settings; a currency already in use always stays selectable.
26.7.1501

Polish pass

A round of refinements to the flows you touch every day — transactions, balances, stats, and sharing an invite.

New
  • Share a group invite straight from your phone's native share sheet — Messages, WhatsApp, wherever your group already talks.
Improved
  • Refreshed the transactions list, balances, stats, and the expense modal for a calmer, faster feel.
  • Owner-only settings are now hidden from members who can't use them, so the settings screen isn't cluttered with things you can't touch.
26.7.1401

Invites, notifications & a new name

Deudin grew up this week: it got its name, a way to pull in the whole group, and a nudge when something changes.

New
  • We're now Deudin (deudin.app) — new name, new home, same app you were already using.
  • Add people as placeholder members and hand out a single-use invite link; whoever opens it claims that member and its balances.
  • Opt in to push notifications per group and get a ping when someone adds an expense or records a payment — your own actions never notify you.
  • Report a bug or send feedback in seconds, right from the avatar menu.
  • New landing pages in English and Spanish for anyone discovering Deudin.
26.7.1201

See the story, crunch the numbers, bring your history

The pieces that turn a ledger into an app you keep coming back to: a full activity feed, a stats view, live sync, and a door out of Splitwise.

New
  • A per-group activity feed showing every expense, payment, edit and membership change — with inline restore for anything deleted by mistake.
  • A Stats tab that turns your ledger into readable totals and trends.
  • Coming from Splitwise? Import a group's CSV export and land with your balances reproduced exactly.
  • Real-time sync so everyone in the group sees the same numbers, live, across devices.
  • Install Deudin as an app — it works offline and launches from your home screen.
26.7.1101

Accounts, groups & your first split

The core loop lands: sign in, spin up a group, log who paid what, and settle up when it's time.

New
  • Create an account and sign in securely.
  • Spin up a group and invite the people you share costs with.
  • Log an expense with multiple payers and flexible splits — equal, exact, percentage, or adjustments.
  • Settle up by recording member-to-member payments, tracked per currency.
26.7.1001

First light

The very first Deudin build — the money engine and the foundations everything else is built on. Small, but the math is already rock-solid.

New
  • A precise money engine that never loses a cent to rounding, with balances tracked independently per currency (no surprise conversions).
  • The ledger and membership model at the heart of every group.
  • The walking skeleton of the app, wired end to end and installable from day one.
Versions follow a date scheme — YY.M.DDNN — so 26.7.1801 is the first release cut on 18 July 2026. Subscribe via the Atom feed.
