Verdict
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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Spamdrain sells 8 in-app purchases, starting at $25.99 per year and Wispo sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
Wispo holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Spamdrain has 1.2K ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 61% of Spamdrain's written reviews are positive against 100% of Wispo's.
Spamdrain ships an update every 2 months, Wispo monthly. The most recent releases landed on November 10, 2026 and October 31, 2026 respectively.
