Voltage Divider

This engineering utility calculates unknown values in a voltage divider circuit. It can solve for voltages or resistor values, displaying ideal and actual resistor options. It also shows current, power, and voltage tolerance.

Highlights
  • Solves for Vin, Vout, R1, or R2
  • Resistor picker with actual values
  • Displays ideal resistor value
  • Calculates voltage tolerance
  • Shows current and power consumption

Read full description

A handy engineering utility that solves for voltages or resistor values in a common voltage divider circuit. Enter three terms (out of Vin, Vout, R1 or R2) and this app will solve for the fourth term automatically. The resistor picker will only let you pick from actual resistor values that exist. It's a great time saving tool for quickly selecting resistor values in a switching power supply design or any other circuit that incorporates a voltage divider. When solving for a voltage, select two resistor values and one of the voltages. The remaining voltage will be displayed automatically. The max and min possible voltages will also be displayed based on the resistor tolerances. The current and power through the divider will be displayed at the bottom of the screen. When solving for a resistor value, select two voltages and one resistor value. The remaining resistor value will be displayed in yellow. This is an ideal value. Use the resistor picker to select an actual resistor value close to that ideal value. You can then tell the app to solve for Vin or Vout to see if the resulting voltage meets your design requirements.

Verdict

The call

The clearest difference is rating: Hacker Clock at 4.5 against Voltage Divider's 2.7. Hacker Clock also leads on update cadence (every 15 months vs every 48 months) and ratings volume (41 vs 3). On price, review sentiment, ads and in-app purchases there is nothing between them.

Voltage Divider costs $1.99 and Hacker Clock $1.99 up front. Neither carries in-app purchases, so what you see is what you pay.

ReceptionRating · Positive reviews · Number of ratings

Hacker Clock holds the better App Store score, 4.5 against 2.7. That said, the two scores are not equally well evidenced: Hacker Clock has 41 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 56% of Voltage Divider's written reviews are positive against 54% of Hacker Clock's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Voltage Divider ships an update every 48 months, Hacker Clock every 15 months. The most recent releases landed on June 23, 2026 and September 25, 2026 respectively.
