When each one wins.

Seedtime

Has the category's best free-form, to-scale canvas for designing a whole property, if an elaborate property map is your priority and budget isn't a concern, it's the layout leader. Just note the layout is paid-only, and rotation/companion are still promised, not shipped.

Planter

A clean, simple square-foot grid with a one-time lifetime option, great if you want straightforward SFG and don't need weather or soil data.

Siltwell

The only one that connects your weather station and soil sensors, ships rotation and companion warnings in the layout today, works offline, and is the most affordable of the three, with honest, cancel-anytime pricing.
