Verdict
The clearest difference is review sentiment: ReadLevel AI at 100% against NSWL's 22%. ReadLevel AI also leads on rating (5.0 vs 2.0). NSWL's advantage is in-app purchases (none vs 3) and ratings volume (14 vs 1). On price, update cadence, ads and iOS requirement 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. ReadLevel AI sells 3 in-app purchases, starting at $2.99 per month. NSWL asks for nothing beyond the download.
ReadLevel AI holds the better App Store score, 5.0 against 2.0. That said, the two scores are not equally well evidenced: NSWL has 14 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 22% of NSWL's written reviews are positive against 100% of ReadLevel AI's.
Both ship on a similar rhythm, roughly every 3 months. The most recent releases landed on August 16, 2026 and August 1, 2026 respectively.
