Amazon / Utilities / FULL BATTERY CHARGE ALARM AND THEFT SECURITY ALERT
REVIEW
A two-trick battery utility that mostly does both tricks.
Ebizzinfotech's combo app sounds a charge-complete alarm and screams if someone yanks the cable. It works, ad breaks and all, and that is the entire pitch.

Fire tablets live on chargers. They sit on kitchen counters running recipes, on nightstands cycling sleep audio, on coffee-shop tables while their owner orders a refill. Two failure modes follow from that lifestyle: the battery cooks itself on a permanent 100-percent trickle, and the tablet walks off when the owner looks away.
Ebizzinfotech’s app is a combo utility built around exactly those two failure modes. One screen, two toggles, a PIN, a sound picker. There is nothing else to learn and nothing else to configure. The pitch is the same as a dozen Play Store equivalents — full-charge buzzer plus cable-unplug siren, free, ad-supported, no account.
It is a single-screen utility doing two unglamorous jobs, and the second job is the one that justifies the install.

FEATURES
Two functions sit behind one toggle each. The full-charge alarm watches the battery level and triggers a chosen ringtone when the device hits 100 percent, with a slider that lets you fire it earlier — 80, 90, 95 — if you are trying to avoid trickle-topping a Fire tablet overnight. The anti-theft alarm watches the charging state: unplug the cable while the alarm is armed and the device sounds at full volume until you enter a four-digit PIN.
The settings are blunt. Pick a tone from the bundled library or point the app at a file on the device. Set volume independently from the system slider so a muted tablet still screams. Toggle vibration. There is no smart-home hook, no notification mirroring to a phone, no scheduling — arm it manually when you walk away from the cafe table, disarm it when you come back.
Screenshots and the listing confirm a single-page UI with three or four big buttons. That is the whole product.
MISSION ACCOMPLISHED
The anti-theft mode is the reason to install. A Fire tablet charging on a coffee-shop counter is an easy grab, and a 100-decibel alarm tied to the charging cable is a meaningful deterrent for the cost of zero dollars. The PIN-to-silence step is the right design choice — a swipe-to-dismiss would defeat the point.
The charge alarm is a nice-to-have that genuinely extends battery longevity if you cannot trust yourself to unplug. Setting the trigger at 90 percent and using any tone louder than a notification chime is the configuration that actually changes behaviour.
ROOM TO IMPROVE
Ad density is the headline complaint in this archetype, and Ebizzinfotech's catalogue is consistent about it. Expect a full-screen interstitial on launch, a banner pinned to the bottom of the configuration screen, and another interstitial when you save settings. None of it interferes with the alarm itself once armed, but the friction of opening the app to change a tone is real. There is no paid tier to remove ads.
The bigger gap is reliability on Fire OS specifically. Amazon's aggressive background-task killing means a long-armed anti-theft alarm can drop if the system decides the app has been idle too long. There is no foreground-service notification keeping it pinned, no battery-optimization exemption prompt, no documentation of how long the arm state survives. Test it on your specific tablet before you trust it with a device worth stealing.
CONCLUSION
This is a free utility that does two things competently and asks for your attention via ads in return. Install it if the cafe-table scenario is a regular part of your life, or if your Fire tablet lives on a charger and you would rather it stopped at 90 percent. Skip it if you want either feature wrapped in a polished, ad-free experience — that app exists on other platforms but not in this listing.
