# Blue vs TELLO

The clearest difference is rating: Blue at 3.7 against TELLO's 2.1. Blue also leads on in-app purchases (none vs 1) and review sentiment (43% vs 27%). TELLO's advantage is ratings volume (92 vs 7) and iOS requirement (8.0 vs 12.4). On price, ads and device support there is nothing between them.

Both are free to download. TELLO sells 1 one-off in-app purchase. Blue asks for nothing beyond the download.

Blue holds the better App Store score, 3.7 against 2.1. That said, the two scores are not equally well evidenced: TELLO has 92 ratings behind it against 7, so its average is the more settled of the two. Written reviews point the same way: 43% of Blue's written reviews are positive against 27% of TELLO's.
