# Spark · vs Lucero

The clearest difference is in-app purchases: Spark · at none against Lucero's 3. Spark · also leads on ads (none vs shown) and rating (4.8 vs 4.4). Lucero's advantage is iOS requirement (13.0 vs 15.0). On price, review sentiment, update cadence and device support there is nothing between them.

Both are free to download. Lucero sells 3 in-app purchases, starting at $4.99 per month. Spark · asks for nothing beyond the download.

Spark · holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: Spark · has 494 ratings behind it against 57, so its average is the more settled of the two. Written reviews complicate that: 77% of Spark ·'s written reviews are positive against 81% of Lucero's, so the app with the better star average is not the one people write more warmly about.

Spark · ships an update every 10 days, Lucero every 3 weeks. The most recent releases landed on November 7, 2026 and November 3, 2026 respectively.
