Verdict

The call

The clearest difference is rating: Lumin at 4.5 against DisplayNote App's 2.1. Lumin also leads on update cadence (every 9 days vs every 2 months) and ratings volume (908 vs 21). DisplayNote App's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, in-app purchases and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Lumin holds the better App Store score, 4.5 against 2.1. That said, the two scores are not equally well evidenced: Lumin has 908 ratings behind it against 21, so its average is the more settled of the two. Written reviews complicate that: 32% of Lumin's written reviews are positive against 50% of DisplayNote App's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Lumin ships an update every 9 days, DisplayNote App every 2 months. The most recent releases landed on September 29, 2026 and June 4, 2026 respectively.
