BenchKit
Read full descriptionHide full description
BenchKit puts four everyday electronics calculations in one focused, offline iPhone app. RESISTOR CODES Decode 3, 4, 5, and 6-band axial resistors by tapping the bands on a drawn resistor, or SMD codes (3-digit, 4-digit, EIA-96, R notation). See the tolerance range, IEC marking code, and standard E-series match, with a warning when a reading is probably reversed. PCB TRACE WIDTH Estimate minimum internal or external copper trace width from current, copper weight, and allowed temperature rise, in millimeters and mils, or the current a given width can carry. Results outside the IPC-2221 chart range are flagged as extrapolations. VOLTAGE DROP Voltage drop, voltage at the load, power lost in the wiring, and the share of supply that reaches the load. Enter the round-trip resistance, or wire gauge (AWG or mm²), length, and conductor temperature. VOLTAGE DIVIDER Ideal unloaded output voltage, divider current, per-resistor dissipation, output resistance, and what an optional load does to the output. Or enter a target voltage and get the closest E24/E96 resistor pairs with their worst-case output. Type values the way engineers write them: 4k7, 2R2, 100m, 3V3; the keyboard has keys for the letters. No account. No ads. No analytics. No network connection. English, Simplified Chinese, and Japanese. BenchKit is a quick estimation tool. Always verify production designs against component datasheets, applicable standards, simulation, and physical validation.

Verdict
The clearest difference is in-app purchases: BenchKit at none against Kanon AI's 6. BenchKit also leads on ads (none vs shown). Kanon AI's advantage is update cadence (every 3 weeks vs every 2 months) and iOS requirement (16.0 vs 18.0). On price and device support there is nothing between them.
