## What is Perfboard Lab?

Understand electronics by trying it out: Perfboard Lab turns your iPhone, iPad or Mac with Apple silicon into an electronics lab. Build a circuit and switch on the power. Right away you see what happens: LEDs light up, buzzers beep, motors turn and hum. And if your maths was off: it smokes, it sparks and the part burns out – without any real damage.

SEE WHAT HAPPENS, INSTANTLY
• Every change is computed instantly with real physics
• Overloaded parts smoke in four levels until they burn out
• The analysis explains in plain words what is wrong: an LED the wrong way round, a missing series resistor, a short circuit, an open circuit

MEASURE LIKE IN A REAL LAB
• Multimeter: voltage, current and power at every part
• Oscilloscope: voltage and current over time

OVER 20 REAL PARTS
• DC voltage source, AC source, current source and breadboard power supply
• Resistors, potentiometers, ceramic and electrolytic capacitors, inductors, switches
• Diodes and Zener diodes, NPN and PNP transistors, N- and P-channel MOSFETs, relays, op-amps, voltage regulators and Timer NE555
• LEDs in six colours, an incandescent lamp, a buzzer with a real tone and a motor whose hum matches its turning
• Real characteristics as in a parts catalogue, each with a short explanation

JUST LIKE ON THE WORKBENCH
• Draw wires with the pen – straight wires with bends and branches
• Perfboard, with Perfboard Lab Pro also stripboard with cuttable strips and breadboard as used with Arduino
• Copy parts with all their values; text labels annotate your circuit
• Real 2.54 mm grid: what fits in the app fits on the real board
• Bill of materials with every part and the length of every wire
• With Perfboard Lab Pro you see your circuit in the 3D view: real parts on the board that you turn, tilt and measure

PERFECT FOR SCHOOL AND CLASS
• A guided tutorial builds your first circuit with you
• AI-assisted tasks and explanations in Perfboard Lab Pro: tasks that suit your level, explanations step by step on the board.
• Lots of ready-made examples: from an LED with a series resistor to logic circuits, transistors and op-amps
• The interactive formula collection adapts to your circuit: with the power on, every worked example calculates with the measured values of your parts and shows where each number comes from.
• Teachers pass their default settings on to the whole class as a file

FOR EVERYONE
• For iPhone, iPad and Macs with Apple silicon
• In many languages and usable with VoiceOver and Voice Control
• No ads, no tracking

FREE
The perfboard with almost all parts and their examples, text labels, the instruments and the simulation are free. A circuit can have up to 7 parts. Your circuit is kept automatically.

PERFBOARD LAB PRO
With “Perfboard Lab Pro” you save as many circuits as you like and keep working on the same circuit on iPhone, iPad and Mac. You export them as PDF with a bill of materials and share them with others. Plus circuits with more than 7 parts, op-amp, voltage regulator, Timer NE555, motor, Zener diode and current source with their examples, the stripboard and the breadboard with their examples, AI-assisted tasks and explanations, and the 3D view.
• Try it free for 3 days, then a weekly subscription. The App Store shows the price in your currency before you buy.
• The subscription renews automatically every week unless it is cancelled at least 24 hours before the end of the period. Payment is charged to your Apple Account. You can cancel at any time in your Apple Account settings under “Subscriptions”.

## Version history (last 3 releases)

### 1.0.2 — 2026-10-27

• 3D view in Perfboard Lab Pro: your circuit appears with real component packages. You rotate, tilt, pan and measure directly in 3D. LEDs light up, and the relay’s armature and contact spring move with the coil current. Without a subscription, a short preview shows the 3D view.
• Keep working on all your devices: with Perfboard Lab Pro, circuits and settings stay the same on all your devices via iCloud.
• New parts: 78xx voltage regulator with selectable output voltage and NE555 timer.
• New examples: multivibrators with the NE555 (astable and monostable) and an astable multivibrator with two transistors. All examples are laid out more clearly and carry a name tag.
• Strips on the stripboard can be cut between two holes and joined again.
• As on a real board, each hole holds only one component lead, and component bodies never touch. Transistors and MOSFETs sit in a TO-92 package, the op-amp in a DIP-8 package like the TL071.
• The formula collection is interactive and adapts to your circuit: with the power on, every worked example calculates with the measured values of your parts and shows where each number comes from. New topics are DC voltage source, current source, incandescent lamp, motor, potentiometer, diode, buzzer, voltage regulator and NE555. Every symbol has a fixed colour in the sketch, the formula and the worked example.
• The oscilloscope shows the waveform live, with time per division, period and frequency.
• In landscape, the app shows only the board, in 2D and in 3D.
• Oscillating circuits are analysed over their whole period.
• A consistent interface: sheets, buttons, panels and lists look and behave the same everywhere.
• Many small improvements.

### 1.0.1 — 2026-10-19

• AI-assisted tasks and explanations in Perfboard Lab Pro: tasks at your level of knowledge and step-by-step explanations of your circuit on the board. On devices with Apple Intelligence, Apple’s on-device model chooses the tasks and explanation steps. All texts are written in advance.
• Formula collection: formulas from R = V / I to reactance. Each formula comes with a labelled sketch, an explanation, the meaning of all its symbols and a worked example using the values of your circuit.
• Copying parts: the copy keeps all values, and a separate button opens the formulas.
• Text labels annotate the circuit, with font size, colour and transparency of your choice.
• Measuring at every terminal: for parts with three or more terminals, the multimeter measures the terminal you tap against GND, for example an input of the op-amp.
• New parts: relays as normally open and normally closed, N- and P-channel MOSFETs, electrolytic and ceramic capacitors.
• New examples on the stripboard and the breadboard.
• Overloaded parts smoke, burn and char. Polarized parts such as electrolytic capacitors and LEDs also break when reversed.
• With AC too, overloaded parts first get hot and smoke before they burn out.
• The simulation goes on after every change: capacitors keep their charge and coils their current.
• The page “Calculation basis” now shows every calculation method with its formula, legend and worked example.
• Accessibility: you can use the app with Voice Control. It follows Reduce Motion, Differentiate Without Color and Increase Contrast.
• Sources limit their current like a lab power supply. Maximum current and maximum voltage can be set.
• A new app icon and many small improvements.
