# Local Sidereal Time vs Beauty Math

Local Sidereal Time and Beauty Math are too close to call on the numbers: across 5 compared parameters — price, ads, in-app purchases and device support among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. Local Sidereal Time sells 1 one-off in-app purchase and Beauty Math sells 3 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
