Verdict

The call

The clearest difference is rating: Wispo at 5.0 against Spamdrain's 4.4. Wispo also leads on review sentiment (100% vs 61%) and update cadence (monthly vs every 2 months). Spamdrain's advantage is ratings volume (1.2K vs 1) and device support (3 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
