User reviews

Short History

The history is too short at only 30 days. It use to show months of usage. Only 30 days is pointless. Need a full 12 months to be able to analyze usage.

Way too simple

Why is there only a 30 day history? Why can't I see gallons? It works but needs way more data

Won’t Scan

Broken on iOS—camera comes up ok but won’t read/scan the QR code. Need a way to manually add a tank monitor.

Solid, but too simple

The monitor is accurate and has key features. It updates at a reasonable frequency.

On the main screen it shows the gallons, but the graph only shows percentage. You have to figure out gallons. Want to see the amount of gallons delivered? Graph carefully, mouse over, multiply… harder than necessary.

More annoying it only shows the last 30 days, not at all useful if you are trying to look at what you used across a season or plan/estimate for a heating season ahead. The competitive apps all have longer history, so if that is important to you do not go with this one.

API for exporting? No.
Integration with home automation? No.
Web version? No.
Export data? No.

UI issues on smaller screens

The UI doesn’t the support smaller viewports of iPhone SE and iPhone 13+. Text goes below the fold and features that should be there are inaccessible. Makes it impossible to link my tanks to my supplier using a supplied code.
