Verdict
Resistor Tools and 計算工坊 are too close to call on the numbers: across 5 compared parameters — price, ads, in-app purchases and device support among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Resistor Tools sells 1 one-off in-app purchase and 計算工坊 sells 9 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
