# R Discovery vs SPSS Software Guide

The clearest difference is price: R Discovery at Free against SPSS Software Guide's $4.99. R Discovery also leads on review sentiment (57% vs 14%) and rating (4.8 vs 3.0). On in-app purchases, monetization model, device support and iOS requirement there is nothing between them.

R Discovery is free to download; SPSS Software Guide costs $4.99 up front. R Discovery sells 6 in-app purchases, starting at $11.99 per month and SPSS Software Guide sells 3 in-app purchases, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.

R Discovery holds the better App Store score, 4.8 against 3.0. That said, the two scores are not equally well evidenced: R Discovery has 924 ratings behind it against 10, so its average is the more settled of the two. Written reviews point the same way: 57% of R Discovery's written reviews are positive against 14% of SPSS Software Guide's.

R Discovery ships an update monthly, SPSS Software Guide every 2 months. Both last shipped on October 24, 2026.
