# DR.Lissajous vs 4D Draw

The clearest difference is rating: DR.Lissajous at 4.5 against 4D Draw's 3.4. DR.Lissajous also leads on iOS requirement (9.1 vs 17.1). 4D Draw's advantage is review sentiment (70% vs 50%) and update cadence (every 7 months vs every 23 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

DR.Lissajous holds the better App Store score, 4.5 against 3.4. Both are backed by a comparable volume of ratings — 2 and 9 respectively. Written reviews complicate that: 50% of DR.Lissajous's written reviews are positive against 70% of 4D Draw's, so the app with the better star average is not the one people write more warmly about.

DR.Lissajous ships an update every 23 months, 4D Draw every 7 months. The most recent releases landed on November 1, 2026 and November 6, 2026 respectively.
