# Screw Guru vs 3D Bolt Master®

The clearest difference is rating: 3D Bolt Master® at 4.9 against Screw Guru's 4.3. 3D Bolt Master® also leads on review sentiment (37% vs 14%) and chart position (#72 vs unranked). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Screw Guru sells 33 one-off in-app purchases and 3D Bolt Master® sells 19 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

3D Bolt Master® holds the better App Store score, 4.9 against 4.3. That said, the two scores are not equally well evidenced: 3D Bolt Master® has 55K ratings behind it against 6.4K, so its average is the more settled of the two. Written reviews point the same way: 14% of Screw Guru's written reviews are positive against 37% of 3D Bolt Master®'s.
