Verdict
The clearest difference is rating: Chart Neo at 4.8 against NFP Charting's 4.3. Chart Neo also leads on review sentiment (80% vs 49%) and update cadence (every 6 weeks vs every 4 months). On price, ads, in-app purchases and monetization model 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. NFP Charting sells 6 one-off in-app purchases and Chart Neo sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Chart Neo holds the better App Store score, 4.8 against 4.3. That said, the two scores are not equally well evidenced: Chart Neo has 72 ratings behind it against 6, so its average is the more settled of the two. Written reviews point the same way: 49% of NFP Charting's written reviews are positive against 80% of Chart Neo's.
NFP Charting ships an update every 4 months, Chart Neo every 6 weeks. The most recent releases landed on June 11, 2026 and September 24, 2026 respectively.
