Verdict
The clearest difference is in-app purchases: KernelAI at none against Textify's 7. KernelAI also leads on ads (none vs shown). On price, rating, review sentiment and ratings volume 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. Textify sells 7 in-app purchases, starting at $0.99 per 7 days. KernelAI asks for nothing beyond the download.
KernelAI holds the better App Store score, 4.6 against 4.4. Both are backed by a comparable volume of ratings — 44 and 38 respectively. Written reviews complicate that: 87% of Textify's written reviews are positive against 80% of KernelAI's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly fortnightly. The most recent releases landed on October 19, 2026 and October 12, 2026 respectively.
