A browser that lets you do everything with one hand. HalfMoon Browser is a lightweight web browser specifically designed for one-handed operation on iPhones. It consolidates operations such as back, search, and tab switching into a "dial" accessible from the edge of the screen, aiming for ultimate comfort by allowing you to complete browsing with just your thumb. β–  Unique dial operation for one-handed use Place your finger on the left or right edge of the screen, and a semi-circular dial will unfold. Simply slide your finger up or down and release to execute the desired function. β€’ Back / Forward / Home β€’ New Tab / Tab Switch / Close Tab β€’ Search / URL Input β€’ Add Bookmark β€’ Instantly jump to the top/bottom of the page β€’ Remove Ads / Share / In-page Search / Auto-scroll / Settings (submenu) Even on larger devices, there's no need to stretch your finger to the center or top of the screen. β–  Extensive customization to create your own preferences The contents of the dial can be edited at any time from the settings. β€’ Add, delete, and rearrange items β€’ Swap left and right dials (switch between dominant and non-dominant hands) β€’ Two operation modes (hold & release / tap switching) β€’ Adjust dial size from 0.8x to 1.8x β€’ Adjust haptic feedback intensity β–  Unprecedentedly powerful ad blocking HalfMoon's ad blocking operates with a three-layer structure. β€’ Layer 1: URL filtering blocks over 200 ad-delivery domains at the communication level β€’ Layer 2: CSS hiding removes ad containers from the screen β€’ Layer 3: Detection bypass (prevents "Please unblock ads" warnings and automatic ad reloads) Furthermore, ads that were not completely blocked by the filter can be manually removed with a single tap from the "Remove Ads" submenu. Hidden selectors are remembered per site, so they will be hidden from the start the next time you open the site. β–  Other Features β€’ Private Browser (Protected by Face ID / Touch ID) β€’ Forced Dark Mode (Inverts white background sites to darker display) β€’ Super Dark (Darks the entire screen, adjustable from 10-85%) β€’ Password Save (Encrypted to Keychain on your device) β€’ Site Data / Download / History Management β–  About the Pro Version Almost all features of HalfMoon Browser are available for free.
