A shared trip, in one place
The group’s plans
and numbers, together.
Contri gives everyone in a trip a shared view of expenses, contributions, and updates.
Invite by code or QR
Share a trip invitation, scan its QR code, or enter the code. New members review the trip before joining.
Track who paid and shares
Record an expense and its payer, then split it equally or use the available exact, percentage, or share-based options.
Explore the Maharashtra route
See the origin, destination, and stops on a Maharashtra state map with subtle curved connectors. Admins can drag pins, add or edit stops, reorder the journey, update dates and completion status, and follow a live progress timeline with place names. Members can view the shared route.
Review settlement suggestions
See the suggested payments from current trip balances. Admins and members with granted access can manage settlement records.
Record advance contributions
Trip admins can record, edit, and reverse advance contributions separately from expenses; members can see the shared contribution history.
Activity and notifications
Follow shared trip activity and manage in-app notifications. Android push alerts are available when push delivery is configured for the account and app.
Manage private receipts
Attach multiple receipt images to eligible expenses, preview them, and retry failed uploads. Receipts stay in private storage; viewing and upload access follow trip membership and permissions.
Profile, settings, and guest access
Manage your profile and appearance preferences, or start with a guest account and link Google later.
Keep useful trip summaries
Export trip summaries as PDF and expense details as CSV when you need a copy.

Privacy & account access
Trip access follows membership.
Contri uses Firebase Authentication and Cloud Firestore for accounts and trip data. Guest access uses Firebase Anonymous Authentication; link Google from your profile if you want an easier way to recover the same account.
This site does not verify which Firestore rules are currently deployed. Share trip invitations only with people you intend to add.
