It has a nice graphic display showing you how the charge is progressing. One downside is that it won’t work unless it’s the app is visible. Major downside is that the ads are obnoxious to some degree and very hard to get rid of! ### 3/5 — Ads are LOUD *2026-06-24, version 2.9.2* Advertisements play very LOUDLY and annoy everyone. ### 3/5 — Loud commercials *2026-06-08, version 2.9.2* Ads are too loud, destroys the usefulness of the app ### 4/5 — Almost perfect *2026-05-30, version 2.9.2* You mute your phone sound for the stupid ads, then you are muted when the alarm goes off? Not great. ### 2/5 — Not working *2026-05-10, version 2.9.1* I just paid the .99cents to remove the ads but when I press the set alarm button nothing happens. ### 2/5 — Not reliable *2026-05-10, version 2.9.1* Worked well for a while and suddenly refused to start. Uninstalled and reinstalled. Still the same problem. What a shame… ### 3/5 — Is this the only way? *2026-04-29, version 2.9* The ads are very annoying and difficult to stop once viewed. ### 4/5 — Weird background sounds *2026-04-08, version 2.9* It is very helpful. But the background sound is very strange! Why? ### 2/5 — Charging options *2026-01-04, version 2.9* Would like to see an option to lock screen while charging. Also would like to be able to adjust the input (like it does automatically in the app ).. would also like better sounds please !! ### 2/5 — Spyware ? *2025-10-08, version 2.9* Promo for an "amazing application" to clean phone. No close button on the ad's page. Likely spyware. ### 4/5 — Won’t turn off the ads *2025-10-08, version 2.9* The app started acting up, so I deleted it and uploaded it again and now it’s showing me ads like I didn’t pay for it. Feels suspiciously done on purpose. Don’t buy it. ### 5/5 — Alarming *2025-09-20, version 2.9* I alarmed and full of energy about how good this app is. ### 5/5 — Great app! *2025-09-12, version 2.9* Works just as advertised-I use it daily ### 3/5 — Kinda works *2025-09-10, version 2.9* If you leave it open and keep your phone from going to sleep then it works as advertises, sounds an alarm when it reaches a charge percentage. But you can’t minimize it or run it in the background. You can’t even allow your screen to turn off. Another thing is minor but you can’t select any percentage. You have to move a slider and pick whatever number is close to what you want. For example, 80% is a widely accepted value. You can move the slider and land on 78% or 83%. ## Most critical reviews (10 lowest-rated) ### 1/5 — ADS ARE LOUD & long *2026-08-07, version 2.9.2* Ads are too long AND LOUD for such minimal app!! ### 1/5 — it has not alerted me *2026-05-15, version 2.9.2* this app just likes giving ads, doesn’t alert you like it promises, might work 2/10 times. not worth it. ### 1/5 — It is NOT reliable! *2026-05-11, version 2.9.2* This is a great little app, and it works just well. However, on tablets and desktops when the ads come in at the beginning, some of them raise the device volume, causing the user to lower the volume which, if the user forgets to bring the volume back up then the alarm cannot be heard. The other issue is that some of the ads do not have an option to get out of the ad without hearing the entire ad even if it’s not something that you want to hear. I recommend they work on that ad feature that creates these two problems. Other than that it’s a great little app to say congratulations. ### 1/5 — Doesn’t alert you when charge is done *2026-04-10, version 2.9* The alarm doesn’t ring to notify you that your phone is fully charged. Defeats the whole purpose of the app. My phone is getting overcharged anyway, bad design. ### 1/5 — Not efficient *2026-03-05, version 2.9* I was looking for a app to remind me when is 20% battery to be charged and let me know when is 80% full but didn’t work at all ### 1/5 — Unreliable *2025-09-29, version 2.9* Sometimes would work and sometimes the alarm failed to go off allowing the phone battery to overcharge the whole night. ### 1/5 — Doesn’t work *2025-05-13, version 2.9* Can’t set to 90%, goes from 88 to 93. Alarm never goes off. ### 1/5 — Alarm not working *2025-04-30, version 2.9* Alarm not sounding so charges to 100% instead if alarming when iPad charges to 80% ### 1/5 — Did not warn me! *2025-04-13, version 2.9* The Alarm is not working! ### 1/5 — Don’t download, it s cks *2025-01-15, version 2.8.2* Cannot turn the buzzer off. ## Most praised reviews (10 highest-rated) ### 5/5 — Works great *2026-09-04, version 2.9.2* Does exactly what it says, nice alarm that warns for overcharging, set it to the % you want. ### 5/5 — Functional and easy *2026-07-10, version 2.9.2* I find the Battery Charge Alarm app easy to use and helpful to maximize battery life. ### 5/5 — Great app *2026-07-02, version 2.9.2* This is a great app to have on your phone if you want to avoid overcharging. ### 5/5 — Good,but... *2026-06-30, version 2.9.2* Not a bad battery app, but doesn't always notify when phone reaches preset percentage point and charges straight to 100% instead. The other thing is very limited on notification tones. Could do with improvement, but its the only one worth downloading thats free considering very little choice from the App Store. 🙃 ### 5/5 — Great but...... *2026-04-14, version 2.9* Too many ads. ### 5/5 — Heinrich *2026-04-01, version 2.9* Hdiwbdidurjfnnfjfufhjfnfnfnfndmfmnc Jd ### 5/5 — Thanks *2026-03-31, version 2.9* Excellent app, just what I was looking for ### 5/5 — Excellent *2026-02-25, version 2.9* Really works! ### 5/5 — It works! *2025-11-26, version 2.9* It’s a great, way to extend battery life. Thank you. ### 5/5 — Does what it says it does. *2025-10-19, version 2.9* Works well --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
