NerdCon

Download and open the app, then grant optional permissions if you want clipboard quick actions or widgets. Create or choose a conversion: select unit or currency categories, or open developer tools such as JSON formatter or encoder. Enter a value or paste text; NerdCon instantly shows precise results and related conversions. Save frequently used conversions as presets, pin them to the home screen widget, or add to favorites for one-tap access. Go to Settings to enable offline mode, choose themes, manage currency rate updates, and customize keyboard and clipboard behaviors.
