# Vidaya vs half

The clearest difference is monetization model: half at freemium against Vidaya's subscription. half also leads on ads (none vs shown) and update cadence (every 4 days vs fortnightly). Vidaya's advantage is ratings volume (4 vs 1) and iOS requirement (15.1 vs 18.0). On price, rating, in-app purchases and device support there is nothing between them.
