Fantastic app from an independent developer, and does exactly what it says on the tin. Wonderfully detailed stats and reports, and a comprehensive wiki. £1.99 is a bargain considering the base app's functionality. Knowing how much work goes into app development, I'm more than happy to pay the subscription fee to support the dev. I'd love to see a 365 day grid import & solar export history in the app (I only see 124 days), but since the data can be exported as CSV it's not a big deal.

Super handy app. A slight mod that would make the widget more useful at a glance is to allow the user to adjust the y axis scale (price) in the app, or auto scale it per week of data. Currently in a 3x1 box the cost line looks like a flat squiggle with the price going up to 85p. Something like -5p to 40p would be more useful

I don't find this app that useful with the Octopus Tracker tariff. It shows half hourly time slots on the graph when I only need daily and the widget does not show the current gas price. I have resized the widget to show just the current price and it would be nice if the price automatically centered in the widget (when it's too small to show the graph). Also a transparent widget background would be nice. App seems very Agile focused but with a little effort could improve the Tracker support.

Hi Ivan, please drop an email to contact@smarthound.uk with the Android version (launcher/flavour) you're using as you shouldn't be able to rescale the widget to anything below 1x4. Not showing gas rate in widget is a technical limitation: background updates are limited by how often you use the app so data wouldn't update if you never open the app.

What's new

Update 4.6.0:
• new: see and explore missing data in detail
• new: accept days with missing data to use in weekly stats or energy reports

Update 4.5.x:
• new: gas reports!
• new: see when electricity is cheaper than gas (fix in 4.5.2)
• new: improved CSV export
