# Sola Bible App vs Protos

The clearest difference is rating: Sola Bible App at 5.0 against Protos's 4.7. Protos's advantage is ratings volume (120 vs 23). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. Sola Bible App sells 4 in-app purchases, starting at $4.99 per 7 days and Protos sells 4 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Sola Bible App holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Protos has 120 ratings behind it against 23, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on November 4, 2026 and November 5, 2026 respectively.
