Easy To Know

This is the official homepage for Easy To Know, an Android application. Easy To Know started as a fast local file-transfer app and has grown into an all-in-one Android toolkit — file sharing, weather, network speed test, alarms, device tools, and a free VPN, all bundled into a single app.

The file-sharing tool creates a temporary WiFi hotspot on the sending device and shares the connection details as a QR code. The receiving device scans the code to connect instantly, and the transfer happens directly between the two phones at local WiFi speed — no mobile data or internet connection needed.

What This App Does:

• Send any file — photos, videos, documents, or apps — directly to another Android device over local WiFi, with no internet, cables, or file size limits.
• Connect instantly by scanning a QR code, with no pairing codes to type.
• Check live weather — current conditions, hourly and 7-day forecasts, air quality, wind, and sunrise/sunset times for your location.
• Run a detailed network speed test — download speed, upload speed, ping, and jitter, with a history of your past results.
• Set strict alarms that require solving a short math puzzle to dismiss, so you can't sleep through them.
• View detailed device information — CPU, RAM, storage, battery health, display, and sensors.
• See every app installed on your device, check its permissions, and uninstall apps you no longer need.
• Analyze your device's storage to see what's taking up space.
• Convert images between JPEG, PNG, and WEBP formats.
• Look up your device's IP address and network details.
• Connect through a free, no-signup VPN for extra privacy while browsing.
• Sign in with your Google account to keep your profile synced across sessions.

Tools Included in the App:

• File Sharing — send and receive files directly between two Android phones over a local WiFi connection, at full local-network speed.
• Weather — current conditions, hourly and 7-day forecasts, and air quality, powered by a free public weather service.
• Speed Test — measure your download speed, upload speed, ping, and jitter, with recent results saved for comparison.
• Alarms — set strict, math-puzzle alarms for times you really can't afford to oversleep.
• Device Info — a full breakdown of your phone's hardware and software specs.
• Apps Manager — browse installed apps, review their permissions, and uninstall unwanted apps.
• Storage Analyzer — see how your device's storage is being used.
• Media Converter — convert images between common formats.
• IP Info — check your device's IP address and connection details.
• Free VPN — connect through a free VPN tunnel for extra privacy, with no account or subscription required.

Who It's For:

Anyone who wants a single, no-clutter app for everyday phone tasks — moving files between Android phones without using mobile data, checking the weather before heading out, testing their internet connection, keeping their apps and storage organized, and browsing with a bit more privacy.

How File Sharing Works:

• Sign in with your Google account.
• On the sending phone, tap "Send Files" and choose a file.
• A QR code appears — scan it from the receiving phone's "Receive Files" screen.
• The two devices connect automatically over WiFi, and the transfer begins.
• The received file is saved to the EasyToKnow folder in Downloads.

The other tools — Weather, Speed Test, Alarms, Device Info, Apps Manager, Storage Analyzer, Media Converter, IP Info, and the Free VPN — are all available directly from the app's home screen, and each works independently of the file-sharing feature.
