# iCircuit vs Blast Pressure

The clearest difference is price: Blast Pressure at $4.99 against iCircuit's $12.99. Blast Pressure also leads on in-app purchases (none vs 2). iCircuit's advantage is update cadence (every 4 weeks vs every 8 months) and chart position (#125 vs unranked). On review sentiment, ads, monetization model and device support there is nothing between them.

iCircuit costs $12.99 and Blast Pressure $4.99 up front. iCircuit sells 2 in-app purchases, starting at $1.99 per month. Blast Pressure asks for nothing beyond the download.

iCircuit ships an update every 4 weeks, Blast Pressure every 8 months. The most recent releases landed on October 23, 2026 and October 20, 2026 respectively.
