In some cases, it is nearly impossible to contact certain services via a telephone line, whether it is a viral phone draw, a state unemployment office, a local post office during holidays, or an office that repairs warranty products. Fortunately, there are some apps that can help you overcome these barriers.

These apps are called "automatic redial" applications, and as the name implies, they work exactly how they work; the app dials numbers for you, but if the line is busy and causes the call to be disconnected, the app automatically re-dials, saving you the hassle of dialing yourself repeatedly. Let the app continue to redial, and eventually you should be able to get on the phone and talk to a live call on the other end.

Why do we need to automatically redial the application

Automatic redials are useful for dialing state unemployment offices, local radio competitions, motor vehicle authorities, post offices during Christmas, state representatives or other government officials, and even grandmothers who are still using dial-up to access the internet. If you hear busy tones repeatedly, an automatic redial can help reduce your workload.

For those who have used landline phones, you may know that this feature is called continuous redialing , but the telephone company uses different names such as duplicate dialing, busy line redialing, or busy number redialing. It even has its own national shortcut for most landline phones – call 66 to start it after hearing a busy tone and call 86 to stop it.

However, mobile operators do not provide the same service code as landlines, and continuous redialing is one of the features that wireless providers skip. Additionally, smartphone manufacturers have not yet adopted built-in software tools to help you automatically redial numbers, although Samsung seems to have had automatic redial on some Galaxy models in the past.

All major phone manufacturers have a double-click redial feature in the built-in phone app, and you can click the call button after you finish the call to call to call again and then click once to make a call. But this requires you to click multiple times yourself, which is where third-party automatic redial applications come in.

Which automatic redialer applications are the best

These types of applications are only available on Android. If you are an iPhone user, you cannot use these apps. What is the reason? Android has fewer restrictions than iOS when it comes to allowing apps to take advantage of the smartphone system. So Android has no problem with the app using the operating system and phone features, and iOS can't do that.

If you search for "automatic redial" in the Play Store, you will find a lot of options. Really, there are many such applications. Most of these applications do the same: automatically redial when the line is disconnected. But some are better than others and provide some useful features you might want to take advantage of. We selected four popular options from the Play Store to see how these very similar apps differ.

You should know that, according to some automatic redial app developers, Android makes their apps unrecognizable tones. This means that if these tones are encountered, the application will not automatically end the call. Instead, you need to hang up manually or wait for the call to time out. Either way, once the call is disconnected, the app should start dialing again.

Automatic dialing expert

If you are looking for a purely customized experience in the automatic redializer, an automatic dialing expert may be your choice. The program provides tuning capabilities for almost all settings, from dialing to call duration, and even custom themes.

While other options in this list provide maximum dials from 101 to 9,999, there is no limit to the auto-dial expert. That is, you can choose to limit the number of times the app calls.

Similarly, the duration of the call is the same. You don't need to limit the duration of the call, but if you want to limit it, you can choose to hang up the call immediately after connecting, or cut it off at most 23 hours, 59 minutes, and 59 seconds.

However, there are three ways to take advantage of its automatic dialing feature. First, you can use it with the regular phone app, but this way you can't set the call duration. Second, you can set it as the default dialer to dial through it instead of your phone app. One way is to dial until it is connected, and when someone answers it ends its process. Another method is to set parameters such as call duration, number of dials, delays, etc.

If you have a lot of phone calls to make, an automatic dialing expert can help you. It supports "automatic redial list", allowing you to string together a series of numbers that the application will process one by one. Each number in the list has its own settings, so you can choose how many times the app tries to dial for each number and how long each number will be called after connecting. The app also allows you to import and export CSV lists, saving you time to manually enter each number.

If you dig deep into the settings of the AutoDial Expert, you'll find some extra features that make the app even more complete. You can use light, dark, or system themes to set the app as the default call app and automatically enable the speakers when dialing.

The app contains banner ads, but they are not boring. It also includes three in-app purchase options: the full premium version without ads ($7.49), the premium version with ads ($2.49), and the ad-free version without advanced features ($4.99). What are these advanced features currently are unclear.

Automatic redial

While it's not the most dazzling app on this list, automatic redialing comes second only to automatic dialing experts in customization. It is also compatible with dual SIM cards if you are looking for an app that can take advantage of both SIM cards on your smartphone.

• Play Store Link: Automatic Redial

First, let's look at our limits: The app allows you to dial up to 9,999 times, which, while far from unlimited, has been many times. You can choose the interval between each dial from one second to five minutes.

While the app doesn't have a traditional call list like the previous two options, it does have a feature for future scheduling calls. As an alarm, you can choose to schedule a call for a specific time and date, or set a repetition frequency you prefer.

You will also find some useful features in the settings, such as automatically turning on the speakers when starting a call, reminding you before the application starts dialing as planned, and automatically ending dialing if the call lasts more than five minutes. Like the AutoDial Expert, the app is compatible with light and dark modes, or set to match system themes.

I have friends who use this app to contact their unemployment office and they have succeeded. So while it's not as versatile as the first two apps, it accomplishes the task. The app has banner ads, but offers an ad-free version of the purchase option for $3.49.

AutoRedial - Quick redialing makes it easy

AutoRedial is not dazzling at all. It has a naive user interface and feature set. That said, if you are looking for a simple app to dial repeatedly in place of your repeated dialing, this is not a bad choice.

• Play Store Link: AutoRedial - Quick Redial Makes Easy (Free)

The application cannot be simpler. Enter the phone number you want, select whether to enable or disable the speaker, and select the number of times the app will dial (from 1 to 101). The three buttons under "Enter Number" allow you to make calls, end calls, and access your contacts. That's all.

At least that's true for the home screen. If you go into settings, you will find more options. You can choose between one second and one minute intervals after redialing, enable or disable the display when redialing, turn the speaker on or off, use Smart Audio Redial, and select your dialing attempts from 1 to 101.

But that's not all about Auto Redial. You can clear call history, view recent calls and view your favorites from the hamburger menu. You can even see any new features that developers want to highlight, although the actual update time of the list is not yet clear.

This is the only app on our list that has no ads and in-app purchases. It has not been updated since January 6, 2021, and it is the longest updated app on the list.

Automatic redial | Call timer

If you think AutoRedial is simple, wait until you see automatic redial (not to be confused with automatic redial of the second app). The app's home screen is minimalist, providing enough functionality to dial any number you need. That said, if you dig deeper, you'll find some other settings that might make this automatic redial worth a try.

• Play Store Link: Automatic Redial | Call Timer (Free)

When you launch the app, you will see a simple screen—you can choose to automatically end the call between 0 and 60 seconds or minutes (0 means the call will not end automatically). Below, you can select the interval for automatic redialing, from 1 to 60 seconds or minutes.

You won't mistakenly think that these are the only features that the app offers, because the location of other features is not obvious. But if you click that plus sign ( ) button, you will find more hidden options in the settings. Here you can choose to set vibration and/or sound alarms 10 seconds before the call ends, which is only useful if the time limit for ending the call is set on the home screen.

You can also control whether the speaker is automatically started, select from ten different background colors, and select a priority number for contacts with multiple numbers. But the real highlight is the "Show hang-up timer", which allows you to continue chatting when auto-end is enabled, and "Call Recording", which records your phone calls directly to your device.

The app has ads, but you can pay $2.49 to purchase Auto Redial | Call Timer Pro to remove them.
