Verdict

The call

The clearest difference is price: Soil Test Pro at Free against iYield's $2.99. Soil Test Pro also leads on ratings volume (14 vs 1). iYield's advantage is rating (5.0 vs 3.7) and update cadence (every 8 days vs every 2 months). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
