Verdict
The clearest difference is price: Soft Sounds at Free against Imperial Converter's $1.00. Soft Sounds also leads on iOS requirement (8.0 vs 17.6). Imperial Converter's advantage is in-app purchases (none vs 1) and update cadence (every 2 days vs every 18 months). On ads and device support there is nothing between them.
