# Silo vs Spark Pulse

Silo and Spark Pulse 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. Silo sells 4 in-app purchases, starting at $6.99 per 7 days and Spark Pulse sells 2 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
