What you get: • Your own buoys: five to start, the nearest to you when location is on, then any of 109 across the North Pacific • Individual swells and the average period, two switches you turn on when you want them • 24-hour comparison, so you can see how conditions have shifted • Recent data at a glance; press and hold a row to log a past reading • Your logbook: tap the pencil to log a reading, name it what you saw, and star it. When a live reading matches a starred log, an amber ring highlights CURRENT • A rotating compass with swell direction on the rim • Buoy School: what every reading means, with CDIP's own definitions and links • Dark display mode for dawn patrol • Feet and Fahrenheit, or meters and Celsius; 12-hour or 24-hour clock • A share card for the current reading No ads.

Verdict
The clearest difference is update cadence: Swell Intel at weekly against Wave Whisperer's monthly. Swell Intel also leads on ratings volume (11 vs 2). On price, rating, review sentiment 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. Swell Intel sells 2 in-app purchases, starting at $2.99 per month and Wave Whisperer sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 5.0 for Swell Intel against 5.0 for Wave Whisperer. That said, the two scores are not equally well evidenced: Swell Intel has 11 ratings behind it against 2, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
Swell Intel ships an update weekly, Wave Whisperer monthly. The most recent releases landed on November 5, 2026 and October 31, 2026 respectively.
