# EE ToolKit vs P&ID

The clearest difference is review sentiment: EE ToolKit at 90% against P&ID's 0%. EE ToolKit also leads on rating (4.7 vs 4.3) and ratings volume (1.4K vs 6). P&ID's advantage is update cadence (every 2 weeks vs every 3 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. EE ToolKit sells 1 one-off in-app purchase and P&ID sells 3 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

EE ToolKit holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: EE ToolKit has 1.4K ratings behind it against 6, so its average is the more settled of the two. Written reviews point the same way: 90% of EE ToolKit's written reviews are positive against 0% of P&ID's.

EE ToolKit ships an update every 3 months, P&ID every 2 weeks. The most recent releases landed on October 21, 2026 and October 20, 2026 respectively.
