Workforce management for shift-based teams.
Shift scheduling · geofenced time clock · absences & availability · team chat

Web app · Website · support@wrenta.co

Wrenta is a full-stack workforce management platform for businesses that run on shift-based schedules — retail, hospitality, logistics, healthcare, and more. Employees get a mobile app for their schedule, a geofenced time clock, absences, availability, and team chat; managers run scheduling, approvals, locations, and reporting from the web dashboard. The UI ships in English and German.

For employees

• Clock in / out with GPS geofencing — attendance is verified at the workplace
• My schedule — upcoming shifts, week view, shift details
• Open shifts — see and claim unassigned shifts
• Absences — vacation, sick leave, and other requests, with entitlements
• Time account — overtime balance and monthly trend
• Availability — recurring weekly availability windows
• Team chat & announcements — with report/block moderation
• Push notifications — shift changes, approvals, announcements

For managers & admins

• Team schedule — all staff shifts for any day, plus shift create/update/swap
• Time-tracking review — accept clocked sessions; auto clock-out for forgotten ones
• Absences, entitlements & swap requests — review and approve
• Employees, locations & roles — manage the org
• Announcements — broadcast to the whole team or selected people

• Mobile — Flutter (Dart), Provider, geolocator for GPS/geofencing, Firebase Cloud Messaging + Crashlytics. iOS 13+ / Android 8+.
• Web — React + Vite + TypeScript, Zustand, Tailwind CSS.
• Backend — Node.js (Express) + TypeScript, Prisma ORM, PostgreSQL, JWT access/refresh auth, Zod validation, server-side geofencing (Haversine).
• Infra — API on Render, web & landing on Cloudflare Pages.

Key decisions

• Geofencing is enforced server-side — the mobile app checks location for UX, but the API independently validates GPS on every clock-in.
• Clock-out is location-optional — captured for records, never blocks the action.
• Forgotten clock-outs are auto-closed at the scheduled shift end and flagged for manager review.

Each repo has its own README with setup steps. In short:

# Mobile (Flutter)
flutter pub get && flutter run

# Web dashboard (React + Vite)
npm install && npm run dev

# Backend (Node + Prisma)
npm install && npm run db:migrate && npm run dev

The mobile app targets the production API (https://api.wrenta.co) by default.

No third-party ad tracking and no selling of data. Location is used only to verify on-site presence at clock-in. Users can delete their account and data from within the app. See the Privacy Policy.
