# SPIDER AUDIO vs Retra

The clearest difference is in-app purchases: SPIDER AUDIO at none against Retra's 3. SPIDER AUDIO also leads on ads (none vs shown) and iOS requirement (10.3 vs 16.0). Retra's advantage is update cadence (every 4 days vs every 2 months) and ratings volume (3K vs 1). On price, rating and device support there is nothing between them.

SPIDER AUDIO ships an update every 2 months, Retra every 4 days. The most recent releases landed on October 20, 2026 and October 23, 2026 respectively.
