Estimated revenue
A model estimate with a likely range, not a reported figure.
No estimate. Apps outside the grossing charts, and some countries, have no reliable rank-to-revenue curve, so we show nothing rather than a guess.
How this estimate is made
Rank: we take the app's best Top Grossing rank on the latest chart day. Category ranks are converted into an equivalent overall rank, because a #10 in Finance earns far less than a #10 overall.
Curve: that equivalent rank is read off a rank-to-revenue curve anchored on public company revenue and market-data reports for the US iPhone App Store.
Country: the curve is scaled per country (Japan is roughly a third of the US, Türkiye under 1%). Where we have no scale, such as China, there is no estimate.
Range: the likely range widens with country, category and chart depth. It is a plausible span, not a statistical confidence interval.
Not included: ads, payments outside the App Store, and any difference between gross sales and what the developer keeps. Low confidence means indirect data; medium means several independent sources agree.

About this app
Text from the App Store listing.
This is a Tesla Powerwall monitoring app, for iPhone and Apple Watch.
See what your Tesla Powerwall is doing at any time, just by glancing at your phone, or wrist! You can launch the app to view an animated display of live data (updated every 10 seconds while it's open), or add a complication to your watch face so that you always know how much battery you have left. Note that complications aren't allowed to refresh as often, so that will update roughly every 30 minutes if you add one.
The app displays solar, battery, grid and home power usage as well as how much charge is left in your Powerwall.
There's two main items in the app, showing live power data as well as a daily summary total telling you how much solar you've generated, home power used and how much grid power you've imported and exported.
Some recent updates: in version 1.4, this support was added for solar only installations. In version 2.5, we added support for multi-site installations. As of version 2.6, this app now uses the official Tesla API as well.
We use this app personally every day and will endeavour to keep it up to date and add more features over time.
Note:
A Tesla Powerwall or a Tesla Solar Installation, and Tesla account are required to use this app. This app supports Tesla's official API, and doesn't see or store your username or password at any point. This app contains no first or third party tracking whatsoever. We take great care to respect your privacy and your data remains your data.
Disclaimer:
This app is not made or endorsed by Tesla. It's built by nerds who couldn't get enough of watching that mesmerising Powerwall animation and wanted it on their watches.
