WattFlow, our real-time charging power monitor for Android, is now live on Google Play. It shows exactly how many watts are flowing into or out of your phone’s battery — live voltage, current, temperature and wattage, no guesswork.
Most phones only show a battery percentage. WattFlow reads the same sensors Android uses internally and turns them into a live wattage number, a session curve and a charging benchmark grade — so you can see whether a charger, cable or wireless pad is actually delivering what it claims.
What's New in v2.0
The 2.0 release adds home-screen widgets in three sizes. The small widget shows live wattage at a glance; the medium widget adds today’s peak in/out and a time-to-full estimate; the large widget layers in a 7-day energy history chart, updating right on your home screen without opening the app.
Also new: an Energy Ledger that logs net Wh gained or lost per day, a Sleep Drain report for overnight battery loss, and a Battery Health trend that flags abnormal degradation using outlier-aware baselines.
WattFlow is free to try, with a Pro upgrade for advanced reports. Download it now on Google Play.
