# Academia.edu vs SciSpace

The clearest difference is review sentiment: Academia.edu at 74% against SciSpace's 13%. Academia.edu also leads on rating (4.8 vs 3.2) and ratings volume (17K vs 6). SciSpace's advantage is in-app purchases (none vs 3). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. Academia.edu sells 3 in-app purchases, starting at $9.99 per month. SciSpace asks for nothing beyond the download.

Academia.edu holds the better App Store score, 4.8 against 3.2.
