Verdict
The clearest difference is rating: SeshatVoice at 5.0 against Voidol's 2.3. SeshatVoice also leads on ads (none vs shown). Voidol's advantage is review sentiment (18% vs 0%) and ratings volume (10 vs 2). On price, update cadence, 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. Voidol sells 12 one-off in-app purchases and SeshatVoice sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
SeshatVoice holds the better App Store score, 5.0 against 2.3. That said, the two scores are not equally well evidenced: Voidol has 10 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 18% of Voidol's written reviews are positive against 0% of SeshatVoice's, so the app with the better star average is not the one people write more warmly about.
Voidol ships an update every 3 months, SeshatVoice every 4 months. The most recent releases landed on October 29, 2026 and October 24, 2026 respectively.
