# Luminus vs Protos

The clearest difference is monetization model: Protos at free with in-app purchases against Luminus's subscription. Protos also leads on ads (none vs shown) and ratings volume (117 vs 4). Luminus's advantage is rating (5.0 vs 4.8) and update cadence (weekly vs every 3 weeks). On price, review sentiment and in-app purchases there is nothing between them.

Both are free to download. Luminus sells 9 in-app purchases, starting at $6.99 per 7 days and Protos sells 7 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Luminus holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Protos has 117 ratings behind it against 4, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

Luminus ships an update weekly, Protos every 3 weeks. The most recent releases landed on October 24, 2026 and October 25, 2026 respectively.
