GrowWise turns your real garden into a living plan: beds to the square foot, a seed box you actually use, and companion planting you can see. Tap a plant. See what belongs beside it. New Companion Mode lets you compare several plants at once and find seeds that work with all of them. PLAN BEDS LIKE THE REAL THING Create raised beds by width and length in feet. Plant vegetables and herbs on a 1-foot grid, undo freely, and keep multiple gardens for different yards or seasons. PLANT WHAT GROWS WELL TOGETHER Green rings mark companions. Red rings mark plants to keep apart. Filter the Seed Box to companions of a plant in the bed—or use Companion Mode to find seeds compatible with a whole grouping. PLANT ON TIME FOR YOUR ZONE Set your location to load USDA growing zone plus last and first frost dates. The planting calendar shows when to start indoors, direct sow, and transplant. Filter seeds by Start now, Sow now, or Transplant now. KEEP A GARDEN YOU CAN TAKE OUTSIDE Open inventory for a seed list, growing notes, and symbol key you can print. Track plantings from seed to harvest, and save seed for next year. GrowWise is built for home vegetable gardeners who want a plan that matches the soil they actually have. Free includes one garden bed (up to 10×10 ft) and the full seed catalog. GrowWise Premium unlocks unlimited beds, larger beds, and custom seeds.

Verdict
The clearest difference is price: GrowWise at Free against SoundSentry's $4.99. GrowWise also leads on update cadence (weekly vs every 2 months) and device support (3 vs 1). SoundSentry's advantage is in-app purchases (none vs 3). On ads there is nothing between them.
