Swell is an algorithmic coaching platform that helps you understand how you're wired, navigate the relationships that matter, and close the gap between what you want and what you do. Most personality tests categorize you into 5-32 personalities, but people are more complex than that. Swell maps you across 63 traits and nine dimensions — your drive, your mind, how you love, how you fight, how you grow. The result is specific, accurate, and the kind of read on yourself that might take a great therapist or a wise friend months to give you. Once Swell knows you, the rest of the app gets sharper. A coach who already understands your patterns. A daily insight tuned to you. Compatibility and friction points with the people in your life & advice on how to work within those dynamics. For those in therapy, a free export you can share with your therapist to help you two get the most out of your sessions. What’s inside: • Your Archetype. A portrait of who you are, made up of behavior patterns identified and validated by therapists and social workers. • A coach who knows you. It'll direct you towards your goals but is also helpful in day to day conflict or venting that comes up. Expect a challenging but supportive tone. • Daily Insight. One sentence a day, pointed straight at you. We take your archetype, any recent relationship or life dynamics we've noticed, and help you see potential blind spots. You can always dive in and learn more. • Connections. Add the people in your life and see where you click, where you’ll likely have friction, and what each person needs from you to be able to meet your needs well. Built for: • People who want to grow but don't know where to start, and tend to want to solve problems on their own. • Anyone navigating a hard relationship – at work, at home, with their friends. • Anyone who’s read a self-help book and thought: great, what now? Your individual data is encrypted. We never sell or share it. Swell offers personal insight and coaching, not clinical treatment. We are not a replacement for therapy (and no AI-driven app truly could be). If you’re in crisis, please reach out to a licensed professional or dial 988. Swell requires a subscription.

Verdict
The clearest difference is monetization model: Withings at freemium against Swell's subscription. Withings also leads on ratings volume (369K vs 11) and chart position (#50 vs unranked). Swell's advantage is iOS requirement (15.1 vs 18.0). On price, rating, update cadence 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. Withings sells 3 in-app purchases, starting at $9.99 per month and Swell sells 3 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.6 for Withings against 4.6 for Swell. That said, the two scores are not equally well evidenced: Withings has 369K ratings behind it against 11, so its average is the more settled of the two.
Withings ships an update fortnightly, Swell every 2 weeks. The most recent releases landed on November 1, 2026 and October 19, 2026 respectively.
