# Observing vs Hearing Amplifier

The clearest difference is in-app purchases: Observing at none against Hearing Amplifier's 19. Observing also leads on ads (none vs shown) and iOS requirement (13.0 vs 16.0). Hearing Amplifier's advantage is update cadence (every 5 weeks vs every 5 months). On price and device support there is nothing between them.

Both are free to download. Hearing Amplifier sells 19 in-app purchases, starting at $0.99 per 7 days. Observing asks for nothing beyond the download.

Observing ships an update every 5 months, Hearing Amplifier every 5 weeks. The most recent releases landed on October 2, 2026 and October 25, 2026 respectively.
