## What is Charging Time?

Charging Time is an app that predicts the time it takes to charge the device where the app is installed.
   
1.Predict how long it will take to reach a specified charge level.
2.The current charging status is used for the next charging prediction.
3.You can manage charging forecast data for each charger.
4.Predictions can also be made for stages in the middle of a specified target charge level.
5.You will be notified by sound and vibration when you reach the target level.
6.There is a function to adjust the expected time.
7.You can set an alarm for the expected time as a calendar event.
8.You can use Widget function.
9.You can use Live Activity.


When it is not in the charging state, it calculates the expected time.
Charging prediction starts automatically when the battery is charged.
Simple screen operation, easy charge level setting, with slider adjustment function when charging time deviates.
You can measure the charging time according to the charging environment, such as the charger you use or charging while using.
You can also predict charging during charging.

If you give permission to use the calendar, you can set the estimated charging time to the calendar event even when the app is inactive. When the target time is reached, a calendar event will start and notify you.

### 5/5 — Better than expectid

*2026-04-08*

I download every free charge time app i could find (which was only around 15 apps though) and this is the one i decided to keep. Only issue is there is a glitch where the settings per icon keep getting reset every time my iPad dies the icons also reset. Single settings don’t have this issue.

**Developer response:** Thank you for your review and for pointing this out.

We identified an issue with the per-icon settings and have released a bug fix to address it.
Please update to the latest version to ensure everything works correctly.
We appreciate your feedback and hope you continue to enjoy using Charging Time.

### 4/5 — Live notifications

*2025-09-14*

Love the app. Would be nice to have a few Live notifications size options. Also, add % symbol nest to the charging level and target. Could add status bar custom options for what to display.  Just a few requests/suggestions.  Overall great app.

**Developer response:** Thank you very much for using our app and for sharing your valuable feedback.
Regarding the % symbol, on smaller screens it can be difficult to secure enough display space, so it is not currently shown.
As for the Widget, the timing of data updates is managed by iOS/iPadOS, so real-time updates every 1 or 3 minutes cannot be guaranteed. Therefore, the Widget displays the predicted charging time calculated by the app itself, and is intended to be used as a reference.
We will take your feedback into consideration when looking at possible improvements in future iOS updates and app enhancements. Thank you for your continued support.

### 1/5 — Not What You Think

*2025-09-12*

I’m not sure what this is actually estimating, but it’s not what you think. It provides an estimated charge time whether or not your device is even plugged in, so it obviously doesn’t account for the actual factors that would determine charging time.

**Developer response:** Thank you for using our app and for sharing your feedback.
This app is designed to estimate the charging time for iPhone and iPad devices.
Charging time can vary depending on many factors, such as the type of charger (cable, wireless charger, mobile battery, car charger), the power output of the charger (for example, 5W, 10W, 30W), the age and condition of the battery, and battery settings in iOS. Charging time may also change depending on how the device is used during charging, such as watching videos or using apps.
Because of these variations, it is difficult to predict the exact charging time from a single measurement. Instead, this app calculates an estimated charging time based on past charging data. In practice, when you charge under the same conditions several times (about 5 to 10 times), the app uses that history to provide a useful estimate for that environment.
In addition, if you use different charging environments (for example, wireless charging or a mobile battery), you can switch icons to record and manage separate estimates.
This app is intended to provide a “reference charging time” rather than an exact result, and actual times may vary depending on the situation.
While the features may not match every request, we hope this explanation helps you better understand how the app works, and that it can be useful for your own charging style.

### 5/5 — Charging Accuracy

*2025-08-31*

This app is really accurate. The charging times are outstanding. One good suggestion would be to have the picture icons labeled with words, like car, portable power bank. But you got to try it and see the effort.

**Developer response:** Thank you very much for using our app and for sharing your valuable feedback.
We truly appreciate your thoughtful suggestion about adding labels to the icons, such as “car” or “portable power bank.” At this time, it is difficult for us to add this feature due to technical factors and the upcoming major iOS update.
That said, your feedback is very valuable and will be taken into consideration when we explore possible improvements in the future.
We are grateful for your support and hope you continue to enjoy the app.

### 5/5 — Good app

*2025-07-25, version 3.5*

This is a really good app! Very underrated ngl!😃

### 4/5 — Could use more info

*2023-09-22, version 1.8*

Nice app. I wonder if you can/is it possible to add more info under each battery setting?  For example the current and voltage input and an alert to indicate that the selected power source does not have enough “juice” to charge the phone. 

Thx.

### 5/5 — Great

*2023-07-11, version 1.6*

It is a great app!
