# PERPLEXIUM vs Primedor

The clearest difference is in-app purchases: Primedor at none against PERPLEXIUM's 4. Primedor also leads on rating (5.0 vs 4.7). PERPLEXIUM's advantage is ratings volume (24 vs 3) and device support (3 vs 1). On price, review sentiment and ads there is nothing between them.

Both are free to download. PERPLEXIUM sells 4 one-off in-app purchases. Primedor asks for nothing beyond the download.

Primedor holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: PERPLEXIUM has 24 ratings behind it against 3, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
