Verdict
The clearest difference is review sentiment: AI helper at 100% against Ninja AI's 56%. AI helper also leads on rating (5.0 vs 4.0) and iOS requirement (13.4 vs 15.1). Ninja AI's advantage is ratings volume (52 vs 4). On price, update cadence, ads and in-app purchases 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. AI helper sells 4 in-app purchases, starting at $1.99 per 7 days and Ninja AI sells 7 in-app purchases, starting at $5.00 per month. Whichever you choose, the download price is not the number that matters.
AI helper holds the better App Store score, 5.0 against 4.0. That said, the two scores are not equally well evidenced: Ninja AI has 52 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 100% of AI helper's written reviews are positive against 56% of Ninja AI's.
Both ship on a similar rhythm, roughly fortnightly. The most recent releases landed on September 7, 2026 and September 8, 2026 respectively.
