# Soul.io vs Sky Stackers

The clearest difference is review sentiment: Sky Stackers at 100% against Soul.io's 53%. Sky Stackers also leads on ads (none vs shown) and update cadence (daily vs every 4 months). Soul.io's advantage is in-app purchases (none vs 1) and ratings volume (8K vs 4). On price, monetization model and device support there is nothing between them.
