There are multiple categories of automation applications that needs to be segregated. It is important to know which niche you are targeting to start off, are you dependent on third party for execution or hold your own IP/ Technology to process requests? There are multiple interface options available but it solely depends on your target consumer segment, in case you have a product spec to address basic functionality and consumer details a staggered approach can be developed.

No clue what "home management" might mean.

Tip: If you need an App to start selling something now, scrap your idea + get a new one.

No App will... create profit...

Start manually... now... today... before sunset...

Once you have more manual sales than you can handle, you might be included to invest in an App.

Tip: Apps are controlled by Google (Android) + Apple (iOS).

Most of my clients have retired their Apps, to escape tracking + cancelling by these... Evil Entities...

Instead they've switched to mobile friendly Websites.
