# iCircuit vs BLExAR

The clearest difference is price: BLExAR at $4.99 against iCircuit's $12.99. BLExAR also leads on in-app purchases (none vs 2) and rating (4.0 vs 3.8). iCircuit's advantage is update cadence (every 4 weeks vs every 3 months) and ratings volume (135 vs 14). On ads, monetization model and device support there is nothing between them.

iCircuit costs $12.99 and BLExAR $4.99 up front. iCircuit sells 2 in-app purchases, starting at $1.99 per month. BLExAR asks for nothing beyond the download.

BLExAR holds the better App Store score, 4.0 against 3.8. That said, the two scores are not equally well evidenced: iCircuit has 135 ratings behind it against 14, so its average is the more settled of the two. Written reviews point the same way: 61% of iCircuit's written reviews are positive against 75% of BLExAR's.

iCircuit ships an update every 4 weeks, BLExAR every 3 months. The most recent releases landed on October 19, 2026 and October 13, 2026 respectively.
