Verdict
The clearest difference is rating: On‑Device AI at 4.4 against MDPeak's 3.7. On‑Device AI also leads on ratings volume (162 vs 3). MDPeak's advantage is review sentiment (100% vs 64%) and monetization model (free vs free with in-app purchases). On price, ads, in-app purchases 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. On‑Device AI sells 4 in-app purchases, starting at $3.99 per month and MDPeak sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
On‑Device AI holds the better App Store score, 4.4 against 3.7. That said, the two scores are not equally well evidenced: On‑Device AI has 162 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 64% of On‑Device AI's written reviews are positive against 100% of MDPeak's, so the app with the better star average is not the one people write more warmly about.
On‑Device AI ships an update fortnightly, MDPeak every 3 days. Both last shipped on October 24, 2026.
