Short answer, don't do it. Save yourself $30. Full review to come shortly, but just in case you saw them recommended by people just putting out lists of available apps but haven't actually used Smart Gardener, don't do it. They are advertising things they don't do, and when I pointed it out, they thanked me for my suggestions. Um...what?
They partner with Baker Creek, yet the majority of information on the seeds they sell aren't here.
You want accurate advice based on specific plants? Nope. You're getting info users inputted. If I wanted info from non-experts, I would Google the answers, not pay for it.
Is Square Foot Gardening easier with this? Nope. The majority of recommended plants per square wasn't right and it won't allow you to customize it.
Anyway, go old school. Write it out. This has been a waste of time.
I thought they don't offer refunds because they didn't want people to get the info they needed and then request a refund. Nope. It's because they know they aren't doing what they advertise. But you can't falsely advertise a product and get paid for it. Now I have to waste more time filing a dispute with my credit card company.
Very frustrating.
