Verdict
The clearest difference is review sentiment: RapidAI at 43% against Viz.ai's 14%. Viz.ai's advantage is rating (4.2 vs 4.0) and monetization model (free vs ad-supported). On price, ratings volume, update cadence 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. Neither carries in-app purchases, so what you see is what you pay.
Viz.ai holds the better App Store score, 4.2 against 4.0. Both are backed by a comparable volume of ratings — 36 and 13 respectively. Written reviews complicate that: 14% of Viz.ai's written reviews are positive against 43% of RapidAI's, so the app with the better star average is not the one people write more warmly about.
Viz.ai ships an update fortnightly, RapidAI every 3 weeks. The most recent releases landed on September 16, 2026 and August 15, 2026 respectively.
