# Echo vs Pitch Hunter

The clearest difference is rating: Echo at 4.9 against Pitch Hunter's 2.3. Echo also leads on ratings volume (36 vs 3). Pitch Hunter's advantage is in-app purchases (none vs 2) and update cadence (every 2 days vs every 9 days). On price, review sentiment, ads and monetization model there is nothing between them.

Both are free to download. Echo sells 2 in-app purchases, starting at $4.99 per month. Pitch Hunter asks for nothing beyond the download.

Echo holds the better App Store score, 4.9 against 2.3. That said, the two scores are not equally well evidenced: Echo has 36 ratings behind it against 3, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

Echo ships an update every 9 days, Pitch Hunter every 2 days. Both last shipped on October 24, 2026.
