We built Siltwell for gardeners who want their beds to work with real conditions. Here we compare three planners so you can decide for yourself.
Seedtime details verified from seedtime.us and its help center, and Planter details from planter.garden and its App Store listing, September 2026. Spot something outdated? Tell us.
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. The free plan draws one layout with up to 8 rectangular beds. Custom bed shapes need a paid plan. Crop rotation is still listed as a future feature.
Planter has a clean, simple square-foot grid with a one-time lifetime option. It's great if you want straightforward SFG and don't need weather or soil data.
On Pro, Siltwell is the only one of the three that connects your weather station and soil sensors. It is also the only one that ships rotation and companion warnings in the layout today. It works offline, and it's the most affordable of the three, with cancel-anytime pricing.
