Split Pro settles the question that ruins group dinners, who owes whom, with a private expense ledger that runs on your own server instead of an ad-supported app. Create a group for the apartment, the trip, or the team lunch rotation, then log each shared cost with its category, currency, date, and a photo of the receipt. Every expense splits your way: equally, by percentage, by shares, by exact amounts, or with manual adjustments when someone covered the tip. Rent, utilities, and subscriptions can repeat on a schedule so recurring bills enter the ledger on their own. The balances view shows exactly who is ahead and who owes, and debt simplification collapses a web of small obligations into the fewest possible payments. Negative expenses record refunds and corrections without breaking the math, and the activity feed keeps a visible history of every edit and deletion. Coming from Splitwise, you can import your friends and groups to pick up where you left off, and bank transactions from supported providers convert straight into expenses. On phones it installs as a progressive web app with push notifications whenever a new expense lands. Logins use email magic links, Google, or your own OIDC provider, and signups can be closed so the instance stays limited to your circle.

TREK coordinates group expeditions and vacations through a collaborative travel planning workspace that unifies daily itineraries, interactive route maps, shared expense budgets, and packing lists. Travel groups can build day-by-day timelines by dragging activities between dates, attaching transit bookings with flight numbers, and estimating driving intervals directly on OpenStreetMap and Mapbox canvases. Instant WebSocket synchronization mirrors itinerary edits, group chat messages, and decision poll votes across all traveling companions simultaneously without page refreshes. The integrated multi-currency expense manager tracks shared expenditures across lodging, dining, and transit categories, automatically calculating per-person debts and generating simplified debt settlement summaries. An interactive world atlas highlights visited nations and tracks lifetime travel statistics, enabling globe-trotters to manage personal bucket lists and review past journeys. Travelers can organize shared packing checklists from reusable equipment templates, monitor real-time weather forecasts powered by Open-Meteo, and export comprehensive travel schedules to printable PDF guides and calendar feeds. Role-based permission controls safeguard sensitive travel documents and boarding pass uploads while allowing guests to contribute notes and vote on activities.

When a family vacation or group expedition spans multiple airlines, hotels, rental cars, and currencies, Surmai brings every reservation and shared cost into one collaborative travel planner. Each trip breaks down into dedicated sections for transportation legs, lodging stays, daily activities, and travel notes. Confirmation codes, terminal numbers, departure times, and street addresses stay right where everyone in your party can find them. Built-in airport, city, and airline directories auto-complete flight routes in seconds, or you can forward booking confirmation emails directly into an active trip for automatic parsing. The chronological itinerary view then weaves flights, hotel check-ins, and excursions into a clean day-by-day timeline so your group can spot layover gaps immediately. Boarding passes, train tickets, and PDF vouchers live inside a central attachment vault. Installing the Progressive Web App caches your entire itinerary and travel documents on your phone for offline viewing at airport gates or remote trailheads. A built-in expense ledger logs shared purchases across multiple currencies so nobody has to guess who paid for dinner. Administrators can invite fellow travelers over SMTP email, enable OAuth2 or OpenID Connect login with Authentik, Keycloak, Google, or Microsoft, and replicate backups continuously to S3-compatible object storage.

When vacations, shared apartments, and group events turn into a tangle of receipts and awkward IOUs, I Hate Money restores harmony with a dead-simple shared budget manager that requires zero user accounts for invited participants. Organizers create a project protected by a private code and share a single link with friends, roommates, or travel companions, allowing everyone to log expenses immediately from any desktop or mobile browser. Each bill entry records who paid, when the purchase happened, what it covered, and which members benefited, supporting both equal splits and custom weighted shares for participants who stayed longer or consumed more. Built-in multi-currency conversion lets international travelers record bills in foreign currencies and convert them automatically into the project default currency. Newly added expense filtering and direct reimbursement bill creation on the Settle screen calculate the minimum number of transfers required to square every balance, while Monthly spending statistics, JSON or CSV exports, and a REST API keep group finances transparent.
