# Chippy Tools vs Fire Pump Calc

The clearest difference is in-app purchases: Fire Pump Calc at none against Chippy Tools's 10. Fire Pump Calc also leads on review sentiment (75% vs 55%). Chippy Tools's advantage is update cadence (every 8 days vs every 8 months) and ratings volume (905 vs 4). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. Chippy Tools sells 9 in-app purchases, starting at $2.99 per 7 days. Fire Pump Calc asks for nothing beyond the download.

Chippy Tools holds the better App Store score, 4.5 against 4.3. That said, the two scores are not equally well evidenced: Chippy Tools has 905 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 55% of Chippy Tools's written reviews are positive against 75% of Fire Pump Calc's, so the app with the better star average is not the one people write more warmly about.

Chippy Tools ships an update every 8 days, Fire Pump Calc every 8 months. The most recent releases landed on September 24, 2026 and August 19, 2026 respectively.
