Verdict
The clearest difference is review sentiment: Synthy at 81% against Speechify's 34%. Synthy also leads on ads (none vs shown) and iOS requirement (16.6 vs 18.0). Speechify's advantage is rating (4.7 vs 4.2) and ratings volume (528K vs 385). On price, in-app purchases, monetization model and device support 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. Speechify sells 8 in-app purchases, starting at $9.99 per 7 days and Synthy sells 7 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.
Speechify holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: Speechify has 528K ratings behind it against 385, so its average is the more settled of the two. Written reviews complicate that: 34% of Speechify's written reviews are positive against 81% of Synthy's, so the app with the better star average is not the one people write more warmly about.
Speechify ships an update weekly, Synthy monthly. The most recent releases landed on November 5, 2026 and November 3, 2026 respectively.
