# Science Now vs Mechanical Engineering Mag

The clearest difference is rating: Science Now at 4.6 against Mechanical Engineering Mag's 3.5. Science Now also leads on ratings volume (140 vs 6) and update cadence (every 3 months vs every 7 months). Mechanical Engineering Mag's advantage is in-app purchases (none vs 3) and ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. Science Now sells 3 in-app purchases, starting at $0.99 per month. Mechanical Engineering Mag asks for nothing beyond the download.

Science Now holds the better App Store score, 4.6 against 3.5. That said, the two scores are not equally well evidenced: Science Now has 140 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 43% of Science Now's written reviews are positive against 71% of Mechanical Engineering Mag's, so the app with the better star average is not the one people write more warmly about.

Science Now ships an update every 3 months, Mechanical Engineering Mag every 7 months. The most recent releases landed on September 24, 2026 and September 21, 2026 respectively.
