# Science Now vs Tech Xplore

The clearest difference is review sentiment: Science Now at 43% against Tech Xplore's 0%. Science Now also leads on rating (4.6 vs 4.2) and ratings volume (140 vs 5). Tech Xplore's advantage is ads (none vs shown) and update cadence (every 3 weeks vs every 3 months). On price, in-app purchases, monetization model 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 and Tech Xplore sells 1 in-app purchase, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

Science Now holds the better App Store score, 4.6 against 4.2. That said, the two scores are not equally well evidenced: Science Now has 140 ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 43% of Science Now's written reviews are positive against 0% of Tech Xplore's.

Science Now ships an update every 3 months, Tech Xplore every 3 weeks. The most recent releases landed on September 24, 2026 and September 10, 2026 respectively.
