# Project vs Milthm

The clearest difference is in-app purchases: Milthm at none against Project's 18. Milthm also leads on ads (none vs shown) and rating (4.9 vs 4.6). Project's advantage is chart position (#137 vs unranked) and ratings volume (1.5K vs 275). On price, update cadence and device support there is nothing between them.

Both are free to download. Project sells 18 one-off in-app purchases. Milthm asks for nothing beyond the download.

Milthm holds the better App Store score, 4.9 against 4.6. That said, the two scores are not equally well evidenced: Project has 1.5K ratings behind it against 275, so its average is the more settled of the two. Written reviews point the same way: 72% of Project's written reviews are positive against 92% of Milthm's.

Project ships an update monthly, Milthm every 2 weeks. Both last shipped on September 22, 2026.
