Hi A,

That sounds like a really neat app. You might want to focus on gardening tools that people might not want to commit to buying right away so they'd have more incentive to use your app. Maybe tools like tillers, sprinklers or even cameras if people are worried about wildlife sneaking in. I'd also offer items specifically for the gardener at work, like lighting for night gardening (I have a neighbor who does this so I promise it's a thing that people do lol) or a Mosquito Magnet to minimize bites.

Good luck with your app!
