User Reviews

Users find the LM317 Calculator app very helpful, easy to use, and useful for electronics design involving LM317 regulators. The projects section and new interface are appreciated. However, multiple users report that ads are intrusive and cause crashes, calculations lack factoring in input voltage, and resistor value inputs can be limited or misleading. Also, the app does not support calculation by voltage inputs and lacks zoom functionality on project circuits, affecting usability and educational value.

Pros

App is clear, concise, and easy to use.
Helpful for calculating resistor values related to LM317 voltage regulator.
Includes a 'projects' section that users find nice and handy.
New interface is appreciated and looks nice.
Users find it useful for designing and building LED drivers and battery chargers.

Cons

Ads are very intrusive and cause the app to crash during calculations.
App does not allow input voltage to be considered in calculations.
R1 resistor values are restricted or can be input outside allowed ranges, causing inaccurate results.
Cannot calculate resistor values by entering desired input or output voltage directly.
No ability to zoom in on project circuits or lacks educational details in projects.

Recent reviews

So far, very nice app.... clear & concise. Admittedly, saves faffing about calculating on paper. .... bit lazy ! One issue is, it does not allow an input voltage to be considered.

R1 can only be 120 to 1K ohms when calculating voltage. This app allows you to enter a resistance that is outside of the requirement making you think it will work when it won't.
