## Review summary

Users find the LED Resistor Calculator & SMD app helpful, easy to use, and accurate for basic LED resistor calculations, with a clean interface including resistor color codes. However, many express frustration with the 60-second delay imposed on the free version, prompting some to uninstall. The app mainly supports single LED calculations and lacks features for series or parallel LEDs, which limits its utility for more complex projects. Despite these drawbacks, its free, ad-free nature and efficiency make it a valued tool for beginners and hobbyists.

### Pros

- Easy to use and helpful for beginners and experts alike.
- Accurate and efficient calculation of LED resistor values.
- Provides color code images for resistors, aiding understanding.
- Free and ad-free app, offering good value without cost.
- Saves time in finding the right resistor for LED circuits.

### Cons

- Free version imposes a 60-second delay on calculations, which frustrates users.
- Feature limitations in the free version push users to upgrade or find alternatives.
- App lacks support for complex circuits such as multiple LEDs in series or parallel.
- Some users report calculations don't always match real-world results, especially for multiple LEDs.
- Limited additional features compared to other apps, such as handling power supply tolerance or LED binning.
