Sow's manual editor rotates objects in 15-degree steps. It's a garden-design app for iPhone built around a photograph of your outdoor space. Place plants and furniture over that picture, with each object available to move or resize as the composition takes shape.
The plant catalogue gives those objects names you can investigate. A plant page includes growing requirements and mature dimensions. In the editor, you can keep changing the arrangement instead of accepting a finished rendering. Sow also offers generated designs, but its design guide describes controls for removing or swapping individual species. That leaves a practical next step when a suggestion looks wrong: inspect the plant and replace it before developing the plan further.
I'm more interested in that editable sketch than in the promise of an automatically suitable garden. US App Store reviews have raised concrete objections: a June reviewer described problems with scale and selecting overlapping objects, while a September reviewer said suggested plants ignored zone and deer-resistance settings. October updates added species and general improvements, but don't establish that those issues are fixed.
I'd consider Sow for exploring a small outdoor space visually. I'd keep measurements and local planting advice alongside the picture, especially before buying plants for it.
