# LUMO vs Zachet

The clearest difference is rating: LUMO at 5.0 against Zachet's 4.5. LUMO also leads on in-app purchases (none vs 4) and review sentiment (100% vs 86%). Zachet's advantage is update cadence (every 4 days vs every 11 days) and ratings volume (51 vs 5). On price, ads and device support there is nothing between them.

Both are free to download. Zachet sells 4 in-app purchases, starting at $17.99 per month. LUMO asks for nothing beyond the download.

LUMO holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Zachet has 51 ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 100% of LUMO's written reviews are positive against 86% of Zachet's.

LUMO ships an update every 11 days, Zachet every 4 days. The most recent releases landed on November 10, 2026 and November 8, 2026 respectively.
