Verdict
The clearest difference is rating: Sunbeam at 4.7 against Luminous's 3.5. Sunbeam also leads on ratings volume (1.7K vs 2) and review sentiment (70% vs 50%). Luminous's advantage is update cadence (every 10 days vs every 4 weeks) and iOS requirement (17.0 vs 26.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Sunbeam sells 2 in-app purchases, starting at $4.99 per month and Luminous sells 3 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
Sunbeam holds the better App Store score, 4.7 against 3.5. That said, the two scores are not equally well evidenced: Sunbeam has 1.7K ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 70% of Sunbeam's written reviews are positive against 50% of Luminous's.
Sunbeam ships an update every 4 weeks, Luminous every 10 days. The most recent releases landed on November 11, 2026 and October 30, 2026 respectively.
