Garden planning apps?

I'm in Springfield, MO and trying to kick off my garden planning for some new raised beds this year, and I want to be more intentional with my planning than I have in the past (e.g. rotation, companion planting, scheduling), and am kind of overwhelmed. Do any of you use gardening apps for planning, and if so, which are worth it? The Farmer's Almanac one is expensive, does anyone have experience using it?

Bonus: if you are in zone 6b and have a spring layout you love, feel free to share!

I appreciate the help!
