Verdict
The clearest difference is rating: OneLLM at 4.6 against Lekh AI's 4.1. OneLLM also leads on in-app purchases (none vs 2) and iOS requirement (16.4 vs 18.0). Lekh AI's advantage is update cadence (every 4 days vs fortnightly). On price, review sentiment, ratings volume and ads 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. Lekh AI sells 2 in-app purchases, starting at $0.99 per month. OneLLM asks for nothing beyond the download.
OneLLM holds the better App Store score, 4.6 against 4.1. Both are backed by a comparable volume of ratings — 26 and 72 respectively. Written reviews complicate that: 56% of OneLLM's written reviews are positive against 57% of Lekh AI's, so the app with the better star average is not the one people write more warmly about.
OneLLM ships an update fortnightly, Lekh AI every 4 days. Both last shipped on November 5, 2026.
