Verdict
The clearest difference is ads: Wahoo at none against ChartedSails's shown. Wahoo also leads on ratings volume (43K vs 2). ChartedSails's advantage is rating (5.0 vs 4.7) and iOS requirement (15.1 vs 18.0). On price, update cadence, 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. Wahoo sells 2 in-app purchases, starting at $4.99 per month and ChartedSails sells 2 in-app purchases, starting at $44.99 per month. Whichever you choose, the download price is not the number that matters.
ChartedSails holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Wahoo has 43K ratings behind it against 2, so its average is the more settled of the two.
Wahoo ships an update fortnightly, ChartedSails every 3 weeks. The most recent releases landed on October 15, 2026 and September 23, 2026 respectively.
