Detector Testers needed an app to show off what their new Bluetooth-connected product line could do, against a hard deadline and a fixed budget. We worked closely with their team so the app did more than meet the brief: it had to make demonstrating the product’s features easy for the engineer holding the phone.
The mobile app and cloud portal behind Detector Testers’ Bluetooth-connected Testifire XTR2 range: test, report, share.
01
The start
A simple request to build an app

02
The journey
Four problems we had to solve
We analysed the requirements fast and set a strategy that would hit the deadline.
- Device ownership by organisation, not by individual
- A complex user experience to make simple
- Hardware still in development while the app was being built
- Controlled distribution of prototypes


03
The result
Test, Report, Share. A world first in detector testing.
The cloud portal gives an instant overview of the work carried out, makes it easy to share test reports with clients, and shows the status of every Testifire XTR2 unit in use. Review and manage reports from all test jobs. Share reports with clients as PDF or CSV. Manage engineer accounts and product registrations. Check product health, smoke levels, battery life and generator life.
Our work with Tappable has evolved from a simple request to build us an app, to them becoming a full & continuous team extension working relentlessly to tight deadlines. Long may it continue.
