Ampere is a small Android app with a clear job: it shows the current flowing into or out of your battery, so you can tell which charger and cable work best on your phone. If you want an Ampere app alternative that does that and also covers alarms, battery health and more, here is how bCare compares as of November 2026, based on Ampere's official Google Play listing.
The short version
Ampere is a focused current meter. Its listing describes measuring charging and discharging current, with widgets, a notification and alerts on the phone and on Android Wear watches in the PRO version. bCare also shows live charging current, then adds full, low and overheat alarms, a measured health score, a ranked list of apps draining battery, family phone sync, Bluetooth device levels and charging animations. The choice comes down to a single-purpose tool or a broader app.
bCare vs Ampere feature comparison
The Ampere column only reflects what its official Google Play listing and the FAQ it links to say as of November 2026. Where they do not describe a feature, the cell says Not confirmed. That does not mean the app lacks it, only that we could not verify it from an official source.
| Feature | bCare | Ampere |
|---|---|---|
| Charge alarm | Yes, at any level you pick, with repeat, snooze, voice announcement and a check that the alarm can ring | Not confirmed |
| Low battery alarm | Yes, at the level you choose, with repeat and snooze | Not confirmed |
| Overheat alert | Yes, alarm at a limit from 35 to 50 °C (42 °C by default) | Not confirmed |
| Health and capacity estimate | Yes, measured mAh from charges of about 20 to 80%, plus a 0-100 health score | Not confirmed |
| Cycle count | Yes | Not confirmed |
| Charging current monitor | Yes, live current, voltage and temperature, plus a check of each new charger | Yes, its main feature: charging and discharging current, averaged over many readings |
| Apps draining battery | Yes, apps ranked by share of screen time over 7 days | Not confirmed |
| Multi-phone sync | Yes, link phones by QR code | Not confirmed |
| Bluetooth device battery | Yes, one battery level per connected device | Not confirmed |
| Widgets | Yes, 7 home screen widgets | Yes, in the PRO version |
| Charging animations | Yes, 6 styles | Not confirmed |
| Languages | 15 | Not confirmed |
| Price model and ads | Free with ads. Optional PRO subscription removes ads and adds extras | Free with ads and in-app purchases. PRO adds widgets, a notification, alerts on the phone and alerts on Android Wear |
Ampere's listing names alerts on the phone and on Android Wear as PRO features but does not say which events trigger them, so the three alarm rows are marked Not confirmed.
What Ampere does well
- One job, done simply. Open the app, wait about ten seconds while it measures, and the current appears. There is little to set up.
- Comparing chargers and cables. The listing is clear that the point is to compare charger and cable combinations on the same phone, which is the question most people have when one cable seems slower.
- Clear about its limits. It explains that the readings are for relative comparison rather than lab accuracy, how the value is averaged from many samples, and that some phones do not expose a suitable measurement interface.
- Watch alerts. The PRO version can send alerts to an Android Wear watch as well as the phone.
- Kept current. The listing shows an update in June 2026 that mentions Android 16.
If you only want to know how many milliamps a charger is pushing, Ampere does that with very little in the way.
Where bCare is different
bCare shows live charging current too, but treats it as one part of looking after the battery rather than the whole app.
- Charger check built in. The live monitor shows current, voltage and temperature as they change. The charger test notices when you plug into a new charger or cable and compares it with the last charger you used: faster or slower, cooler or hotter, steady or not.
- Alarms you can rely on. A battery full alarm at any level, an 80% charge alarm and a low battery alarm, each with repeat, snooze and voice announcement. An alarm-ready check covers notifications, battery optimisation and autostart and plays a test alarm.
- Heat warnings. The overheat alert rings when the battery passes a limit you set between 35 and 50 °C, 42 °C by default.
- Battery health. The battery health check measures capacity in mAh from charges of about 20% to 80%, counts charge cycles and gives a 0-100 score.
- What is using power. Apps draining battery ranks your apps by share of screen time over the last 7 days and points out settings costing power right now.
- Other devices. Link family phones by QR code with family devices and see one battery level for each Bluetooth earbud, watch or speaker you connect.
- Widgets and animations. Seven battery widgets and six charging animation styles.
bCare is available in 15 languages and has 100K+ downloads on Google Play. Charge alarms, live readings and temperature alerts are free; an optional PRO subscription removes ads and adds extras.
A note on current readings
Any app that shows charging current, bCare and Ampere included, can only show what the phone reports. The figure is the current going into the battery after the phone has taken what it needs to run, so it is usually lower than the number printed on the charger, and it drops as the battery fills. For a fair test, compare chargers at a similar charge level, with the screen in the same state and nothing heavy running.
Which should you choose?
- Choose Ampere if you want a minimal current meter for comparing chargers and cables, or you want those readings and alerts on an Android Wear watch.
- Choose bCare if you want current readings as part of a wider battery app: alarms at the level you pick, heat warnings, measured health and cycles, the apps using the most power, and battery levels for family phones and Bluetooth devices.
Both are free to install, so try them with the chargers you own. See all app comparisons for more.
