The clearest difference is rating: Smart Diffuser at 5.0 against SpamSafe's 4.5. Smart Diffuser also leads on in-app purchases (none vs 15) and device support (3 vs 1). SpamSafe's advantage is update cadence (every 3 weeks vs every 5 months) and ratings volume (4.8K vs 3). On price, ads and iOS requirement there is nothing between them.

Both are free to download. SpamSafe sells 15 in-app purchases, starting at $6.99 per 7 days. Smart Diffuser asks for nothing beyond the download.

Smart Diffuser holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: SpamSafe has 4.8K ratings behind it against 3, so its average is the more settled of the two.
