The technician app is built offline first: the day's jobs are on the phone, the whole visit can be done without a connection, and everything syncs by itself when the phone is back online. **Availability:** Android and iPhone apps are built and being prepared for store release; the phone web app works today.

A lost network means a lost visit record. ### The whole job offline See the job, follow the checklist, take photos, record readings, add parts used and collect the customer's signature without a connection. ### Safe sync Each change is sent once and only once. If the office changed the job in the meantime, the app says so in plain words instead of overwriting anything. ### Readings that mean something Record pressure, conductivity, TDS, pH and other readings. They are judged against your own bands for that kind of system. ### Parts and stock Record the filters and parts used. They come off the technician's van stock and can go on the invoice. ### Arrival check When a technician starts work the app checks they are at the site. It never blocks the work, it only lets the office know when something looks off. ### Notifications Reminders for today's visits and changes to assigned jobs arrive as push notifications on Android. Illustration: each change is stored on the phone, sent once when the network returns, and checked against the job as it is now.

Questions ## About technician phone apps **### Is there an Android app and an iPhone app?** Both have been built, with the same offline design. They are being prepared for release in the app stores. A phone-friendly web version for technicians works in any modern browser today. Ask us about the current status. **### What happens if two people change the same job?** The app compares the change with the job as it is now. If it can no longer be applied, the app tells the technician why and nothing newer is overwritten. **### Can the technician turn off location sharing?** No. Location is shared with the office while the technician is working a job, and the company can also choose working hours for it. Technicians are told clearly when it is on. ## Works together with [Live trackingSee who is on the way, and send customers a link that shows the technician arriving.](https://aquasops.com/features/live-tracking)[Jobs and schedulingBook, assign and follow every service visit, from the first request to the closed job.](https://aquasops.com/features/job-management)[Inventory and partsKnow what is in the store and on each van, and put parts used on the job and the invoice.](https://aquasops.com/features/inventory) ## See it with your own kind of work Book a short demo.
