# EE ToolKit PRO vs iCircuit

The clearest difference is rating: EE ToolKit PRO at 4.9 against iCircuit's 3.8. EE ToolKit PRO also leads on in-app purchases (none vs 2) and review sentiment (90% vs 61%). iCircuit's advantage is update cadence (every 3 weeks vs every 3 months) and chart position (#114 vs unranked). On ratings volume, ads, monetization model and device support there is nothing between them.

EE ToolKit PRO costs $9.99 and iCircuit $12.99 up front. iCircuit sells 2 in-app purchases, starting at $1.99 per month. EE ToolKit PRO asks for nothing beyond the download.

EE ToolKit PRO holds the better App Store score, 4.9 against 3.8. Both are backed by a comparable volume of ratings — 293 and 134 respectively. Written reviews point the same way: 90% of EE ToolKit PRO's written reviews are positive against 61% of iCircuit's.

EE ToolKit PRO ships an update every 3 months, iCircuit every 3 weeks. The most recent releases landed on September 21, 2026 and September 24, 2026 respectively.
