An app that works offline for tracking — no internet, no cloud, no account

For rural signal, flights, hospitals and basements: why a tool with no server is the only 1 that never says “reconnecting”.

Open a cloud tracker in a basement or on a farm and you get a spinner. Your data is on a server you can’t reach. The irony: the thing you wanted to record is a number, and your phone has had the capacity to store a number since 1999.

Why most apps need internet

What the connection is actually for
Syncing to the company’s database
Sending analytics
Loading ads
Checking your login
Checking your subscription

None of those are for you. Remove them and nothing is left that needs a signal.

If you want a backup, export a file when you’re back in range. That is the only time a connection needs to be involved.
