Independent Android developer
CompuJohnny builds focused utilities for reading, editing, and moving files. Every app is designed to be understandable, dependable, and honest about how it handles your data.
Our apps
CompuJohnny apps are built for Google Play with no ads, no subscription, and no CompuJohnny account.
Read, organize, crop, scan, and export PDFs on your Android device. PDF Grove keeps document work local and always saves edits as a new copy.
Free to download, with an optional one-time Pro unlock for unlimited prepared reading and Smart Book Crop.
Share selected Android files directly with nearby devices over the same Wi-Fi or a temporary phone hotspot—without sending them through a CompuJohnny cloud.
Same-Wi-Fi sharing is free. Three completed hotspot browser sessions are included, followed by an optional one-time Browser Pro unlock.
The approach
Important actions, permissions, limits, and system handoffs are explained in plain language.
Each app follows Android conventions and adapts across its supported screens and versions.
Every app explains what it can access, what stays on the device, and which outside services are involved.
Support and privacy
For app support or privacy questions, include the app name, Android version, and a short description of the issue. Do not email passwords or private documents.
