# NIST vs StudyIB

The clearest difference is in-app purchases: NIST at none against StudyIB's 6. NIST also leads on iOS requirement (13.0 vs 17.1). StudyIB's advantage is device support. On price there is nothing between them.

Both are free to download. StudyIB sells 6 in-app purchases, starting at $10.00 per month. NIST asks for nothing beyond the download.
