## Description

⚡ Your 100W charger might be charging at 8W — and you&#39;d never know.<br><br>A worn cable, a dusty port, a misaligned wireless pad or a hot battery can silently cut your charging speed by 90%. Your phone still says &quot;super fast charging&quot;. WattFlow shows you what&#39;s actually happening.<br><br>WattFlow is an honest, real-time meter for every watt that flows in or out of your battery — plus real tools to understand what&#39;s going on with your charging and your battery&#39;s health.<br><br>LIVE, TRACKED<br>• Live watts refreshed every second — charging in, draining out<br>• Wired (AC / USB / dock) and wireless, detected automatically<br>• Voltage, current, temperature and battery level at a glance<br>• Peak In / Peak Out tracking and a live 60-second power graph<br>• Animated charge flow — watch the current move<br>• Home screen widgets (Small/Medium/Large) with a 7-day charging chart<br><br>FIND THE PROBLEMS<br>• Charging Benchmark — grade your charger and cable in 60 seconds<br>• Charging Q&amp;A — 14 common questions answered with real measured data, wired and wireless, across multiple devices<br>• Report an inaccurate reading — compare against your own USB power meter<br><br>THE HONEST NUMBER<br>WattFlow shows battery-side power — what actually reaches (or leaves) your battery, not the marketing number on the charger brick. That&#39;s why it can read lower than the charger&#39;s own display: conversion losses and system drain are real, and knowing the difference is the whole point.<br><br>BUILT FOR EVERY SCREEN<br>Adapts to phones, tablets, foldables and Chromebooks — the same real data, laid out for the screen you&#39;re on.<br><br>WATTFLOW PRO — one-time purchase, yours forever<br>• 24/7 background history — every charge and discharge session logged automatically, even with the app closed<br>• Energy Ledger — daily energy in vs. out, at a glance<br>• Sleep Drain — how much battery you lose overnight, and why<br>• Battery Health Trend — is your battery actually degrading, or is that reading just noise?<br>• Floating watts overlay — a draggable live-watts pill over any app<br>• Adjustable charge and low-battery alert thresholds<br>• CSV export<br><br>Zero permissions by default. No ads. Your data stays on your device.
