Why no battery app for tablets and laptops

I've been wondering why no one has ever created a battery app with live tile for tabs and laptops? There are plenty on WP. Would be nice to see an updated percentage on my Start Screen.

I agree. I was wondering the same thing when I got my Surface 2 last year. I think there are a few in the store but they look like crap and reviews were all bad. I really wish Insider Pro was a universal app. Love it on my phone.

I know nothing of developing apps but I wonder if there is something in the OS that prohibits battery monitoring.
