# EveryCircuit vs SISO Calculator

The clearest difference is review sentiment: SISO Calculator at 100% against EveryCircuit's 51%. SISO Calculator also leads on rating (5.0 vs 3.0) and in-app purchases (none vs 1). EveryCircuit's advantage is ratings volume (67 vs 3) and iOS requirement (9.0 vs 14.0). On price, ads and device support there is nothing between them.

Both are free to download. EveryCircuit sells 1 one-off in-app purchase. SISO Calculator asks for nothing beyond the download.

SISO Calculator holds the better App Store score, 5.0 against 3.0. That said, the two scores are not equally well evidenced: EveryCircuit has 67 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 51% of EveryCircuit's written reviews are positive against 100% of SISO Calculator's.

EveryCircuit ships an update every 3 months, SISO Calculator every 5 weeks. The most recent releases landed on October 24, 2026 and October 20, 2026 respectively.
