URL Helper vs PID Controller Simulation
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
URL Helper
Read full descriptionHide full description
Entering URLs isn't really fun. Most of the time only the domain name varies while the rest consists of standard parts with a lot of special characters which are error prone to enter. This application makes it easy and fast to enter even complex URLs correctly, especially for non HTTP protocols. It has separate fields for the protocol, subdomain, domain, top level domain, port, path and fragment part (#) of a URL.

Verdict
The clearest difference is update cadence: PID Controller Simulation at every 3 months against URL Helper's every 19 months. PID Controller Simulation also leads on price ($3.99 vs $4.99). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
