Put DroxQ on your phone

Installed, it opens like an app and keeps working where the signal doesn't. That last part is the point: a compound with no bars is exactly where a form gets filled in.

Forms work with no signal
Download a worksheet, ITR or diary day before you leave. Fill it in on site and it sends itself when you get signal back.
Camera and location built in
Photos and a GPS reading attach to the record, and are kept on the phone until they can be uploaded.
Voice notes
Say in twenty seconds what nobody types one-handed in the rain.

Android

Open this page in Chrome.
Tap the three dots at the top right.
Tap Install app, or Add to Home screen.

Open it from the home screen icon, not from a browser tab. A tab has its stored work cleared after a week of not being used, and anything filled in offline lives there until it sends.
