# StatSync vs Spire

The clearest difference is ads: StatSync at none against Spire's shown. Spire's advantage is update cadence (every 3 days vs every 4 weeks). On price, in-app purchases, device support and iOS requirement there is nothing between them.

StatSync ships an update every 4 weeks, Spire every 3 days. The most recent releases landed on October 1, 2026 and October 10, 2026 respectively.
