# Echo vs QR2Go

The clearest difference is rating: Echo at 4.9 against QR2Go's 4.0. Echo also leads on ratings volume (36 vs 1). QR2Go's advantage is in-app purchases (none vs 2) and update cadence (daily vs every 9 days). On price, ads, monetization model and device support there is nothing between them.

Both are free to download. Echo sells 2 in-app purchases, starting at $4.99 per month. QR2Go asks for nothing beyond the download.

Echo holds the better App Store score, 4.9 against 4.0. That said, the two scores are not equally well evidenced: Echo has 36 ratings behind it against 1, so its average is the more settled of the two.

Echo ships an update every 9 days, QR2Go daily. Both last shipped on October 24, 2026.
