Kixx turns everyday walking into a social game. READ YOUR STEPS Connect Apple Health to bring your step count into Kixx. See daily progress and compare your pace with friends. CLIMB WEEKLY LEAGUES Move through competitive weekly standings powered by real walking. Follow your position and see what it takes to move up. EARN AND COLLECT Hit your daily goal to fill Chests and earn Stars. Use your progress to collect Walkers and curated taunts. CHALLENGE FRIENDS Race friends in Daily Duels and Squad challenges. Choose optional wagers of earned Stars: the amount is shown before entry, you can lose your stake, and eligible steps decide the winner. Stars have no cash value, cannot be cashed out, and cannot buy real-world prizes. No real-money purchases are offered. RECORD A WALK Start an optional GPS walk to measure distance and draw your route. Kixx removes the beginning and end of eligible routes before saving the privacy-trimmed route to your private walk history. You decide when to export a share card. STAY IN CONTROL Apple Health, Contacts, precise location, photo selection, and Notifications are optional. Kixx asks for system access only when a feature needs it, and Photo Overlay uses Apple's photo picker without uploading the selected photo to Kixx. Use handles and invite links without Contacts. Report or block another player from their profile. Delete your account and associated data in Settings. Kixx is a social walking game, not a medical device, and does not provide medical advice.

Verdict

The call

[solidcore] and Kixx both sit at 4.9 stars, but that hides the real split: 100% of Kixx's written reviews are positive against 21% of [solidcore]'s. Kixx also leads on ads (none vs shown) and update cadence (every 10 days vs every 6 weeks). [solidcore]'s advantage is ratings volume (29K vs 7) and chart position (#148 vs unranked). On price, rating, in-app purchases and monetization model there is nothing between them.
