# MechaSense vs QR

The clearest difference is in-app purchases: MechaSense at none against QR's 3. MechaSense also leads on ads (none vs shown) and rating (5.0 vs 4.6). QR's advantage is update cadence (fortnightly vs every 5 months) and ratings volume (1.1K vs 1). On price, device support and iOS requirement there is nothing between them.

Both are free to download. QR sells 3 in-app purchases, starting at $9.99 per 7 days. MechaSense asks for nothing beyond the download.

MechaSense holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: QR has 1.1K ratings behind it against 1, so its average is the more settled of the two.

MechaSense ships an update every 5 months, QR fortnightly. The most recent releases landed on September 18, 2026 and September 26, 2026 respectively.
