YOUR DOWNLOAD

Android APK, version 1.12.0 (approximately 85 MB). Requires Android 8.0 or newer. One-time price: $4.99 USD, plus any applicable checkout tax. No ads or subscription. The installed calculator works offline.

INSTALLATION

After purchase, download the APK on your Android phone and open it. Android may ask you to allow installation from the browser or file manager you used. Follow your device prompts; keep security scanning enabled. School- or employer-managed phones may restrict installation. This is a direct Android download, not an iPhone app or a Google Play installation.

The floating icon is optional and requires Android permission to display over other apps. Standard calculator use does not require this permission.

Step-by-step explanations are available for supported problem types. Check your expression, domain and angle mode, and verify important results independently.
