Trades & service
Fitters see their jobs, navigate there, document with photos, get a signature and record the time – the office writes the invoice from the job.
The app for your phone – for families and field staff. Installable, works offline, with your own branding. On your own server.
uttek Unterwegs is a mobile web app (PWA) with two editions: Private with appointments, tasks, a shared shopping list, notes, photos, expenses, trips and family sharing – Business with customers, jobs, navigation, time tracking, photo log with on-site signature, quote & invoice as PDF, trips, team and interfaces to the uttek tools. Big buttons, iPhone-friendly, offline with sync. You design branding, menu and modules in the app cockpit on your PC. Self-hosted, full source code, no subscription.
Live demo without sign-up · your own demo copy with fictional sample data (electrical contractor, family) · uploads and cockpit publishing off · administration view-only

The important things happen on the move: at the customer, in the car, in the supermarket, at the football pitch. Yet jobs are on scraps of paper, working time is filled in from memory in the evening, job photos vanish into the phone gallery and the shopping list is stuck on the fridge at home.
uttek Unterwegs brings all this into one app that installs like a real app – without an app store, straight from the browser on iPhone and Android. Big buttons, a plus button for everything new and a start page with what is on today. Entries saved without a connection are synced automatically once you are back online.
The Business edition is for trades, service and field staff: jobs with customer, address and one-tap navigation, start and stop time on the job, before/after photos, the customer’s signature on the phone and a proof of work as PDF, quote and invoice from the job, trips and a team overview “who is where today?”. Via ready-made interfaces the app fetches customers, jobs, appointments, shifts, tickets and staff from uttek Customers, Dispo, Mail & Calendar, Rota, Tickets and HR and reports trips and times to uttek Mileage Log and uttek Time – set up in the administration with address and token, test button and sync on/off per module. The Private edition is for family and household: shared appointments, shopping list, tasks, notes, photos, household expenses and trips – shared with up to 6 people.
Starts with SQLite – no database setup. As your business grows, switch to MySQL/MariaDB (PostgreSQL optional) with the admin wizard: test the connection, migrate all data, verify counts, switch over – with rollback.
The upgrade wizard is a uttek standard and is being built into every tool in upcoming versions.
With uttek Connect you link your uttek tools by address and key: tickets become Dispo jobs, customer data comes from the CRM, feedback lands in the ticket and the customer history, shop orders in the CRM – at no extra cost and without a cloud middleman.

No. uttek Unterwegs is an installable web app (PWA): open the address in the browser, “Add to Home Screen” – it then starts like an app with its own icon, on iPhone and Android. Updates arrive automatically via your server.
Yes. Recently opened pages stay readable offline, new entries (appointments, tasks, notes, trips, expenses, times) are stored on the device and sent automatically once you are back online. Photos are uploaded when you next have a connection.
The tier decides the edition. Private is for family and household: appointments, tasks, a shared shopping list, notes, photos, expenses, trips and sharing with up to 6 people. Business is for companies: customers, jobs with navigation, time tracking, photo log with signature, quote & invoice, team, statistics and interfaces. Business Enterprise adds PostgreSQL and an audit-proof change log.
A small application that runs locally on your PC (Windows, macOS, Linux – start script or simply open index.html, no installation). There you design logo, colours, icons, app name, menu order and bottom bar, switch modules on and off, define which role sees what and adjust texts in German and English – with a live preview in a phone frame. Publishing is signed with a token (HMAC-SHA256); every version is stored and can be rolled back. You download the cockpit in the administration.
Prepared are customers from uttek Customers, jobs from uttek Dispo, appointments from uttek Mail & Calendar and uttek Community, shifts from uttek Rota, tickets from uttek Tickets, staff from uttek HR and albums from uttek Media Library – and in the other direction trips, times and completed jobs. Set-up is in the administration: enter the remote system’s address and token, “Test”, then switch sync on or off per module; “Sync now” fetches immediately, otherwise every 15 minutes.
No. The trips in uttek Unterwegs are a simple list (kilometres, destination, purpose). For a tax-office-proof logbook, report the trips to uttek Mileage Log via the interface.
In the Private edition up to 6 family members. In Business and Business Enterprise as many app users as you need that you create yourself with roles (office, field staff) – no price per user.
