Use the Google Play badge below to open the PropelMapper listing. Check that the developer is PropelMapper Inc, then tap Install on your Android phone.
Open the app and sign in with the same email address as your web account. Your visits belong to that account, so you can capture them on the phone and return to them in the browser at your desk.
If you are new to PropelMapper, start 45 days free on this site first. Use that email when signing in on Android so your phone and browser work stay together.
In the field, record voice notes, take photos, enter readings or type observations. Each capture keeps its location and time, giving the report a record of what you saw and where you stood.
You can keep capturing without a signal. Captures save on the phone and upload when you reconnect. Transcription, new report drafts and sending require a connection.
Prepare for a visit without coverage
Sign in while you have a connection and download the offline maps you need before heading out. The phone can save captures and draw or walk a boundary away from cell service. A report draft already downloaded to the phone can also be reviewed and signed offline.
Before your first disconnected visit, make a short recording while online and check that it appears in your web account. Then try a voice note and photo without coverage and reconnect to check the upload. This gives you a chance to check microphone and location access on the phone you will carry, rather than discovering a setup problem at the field gate.
After reconnecting, let the waiting captures upload before expecting a new draft. Review the report against your notes and photographs, correct the wording and send it when it is ready for the client.
Use Android and iPhone on one team
Colleagues can use either phone platform for field visits and use the web app for maps, shared places, tasks and contacts. Browser work needs an internet connection. Clients receive the exported report without having to install the field app.
The recording screen shown here was captured on iPhone. For the current Android screens and installation requirements, see the Google Play listing.
