# Electronic Toolbox Pro vs iCircuit

The clearest difference is rating: Electronic Toolbox Pro at 4.7 against iCircuit's 3.8. Electronic Toolbox Pro also leads on in-app purchases (none vs 2) and review sentiment (93% vs 61%). iCircuit's advantage is update cadence (every 4 weeks vs every 2 months) and chart position (#180 vs unranked). On price, ratings volume, ads and monetization model there is nothing between them.

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

Electronic Toolbox Pro holds the better App Store score, 4.7 against 3.8. Both are backed by a comparable volume of ratings — 245 and 135 respectively. Written reviews point the same way: 93% of Electronic Toolbox Pro's written reviews are positive against 61% of iCircuit's.

Electronic Toolbox Pro ships an update every 2 months, iCircuit every 4 weeks. Both last shipped on October 15, 2026.
