An auto redial app keeps calling a busy line for you until it gets through. RMDialer does it on Android: 3, 5 or 10 tries at your gap, stopping the moment someone answers.

Short answer
An auto redial app is a phone app that keeps ringing one busy number by itself, a set number of times with a pause between tries, and stops once somebody picks up. RMDialer is one for Android: 3, 5 or 10 tries at a gap of 10, 20 or 30 seconds, it stops the moment the call log shows an answer, and redialling one number is free.
Key takeaways
Six reasons to let the app chase a busy line instead of tapping redial by hand.
The phone keeps trying the busy line while you get on with something else, and tells you when it gets through.
After every try the app checks the call log for talk time. The first try that shows it ends the redial.
Each try rings for 30, 45 or 60 seconds, your choice, and is then cut so the next one can start on time.
Three, five or ten, never more. Enough to get through to a busy helpline without becoming a nuisance.
The attempts and the call that connected stay in that number’s history, next to its notes and reminders.
Redialling a single number is part of the free dialer. Calling a whole list again is the paid list feature.
Four choices on one sheet, opened from the ⋮ menu of any number’s Call Details.
3, 5 or 10. The app never goes past 10, because calling one number more than that stops being persistence.
10, 20 or 30 seconds between the end of one try and the start of the next, so the line has a moment to clear.
30, 45 or 60 seconds, then the try is cut, so an unanswered try does not ring for a full minute before the network drops it.
After each try the app reads the phone’s call log. The moment a try shows talk time, redial stops and tells you who answered.
The try is cut after the ring time you chose while RMDialer is your phone app, which is also what lets it dial by itself. What auto redial means, and how to find a redial switch in a phone’s own settings, is explained on the auto redial glossary page.
Your phone may already redial, and single-purpose redial apps fill the Play Store. Here is where each one stands, described in general terms.
| Compared on | RMDialer Auto redial | Your phone’s own redial | A single-purpose redial app |
|---|---|---|---|
| Where you start it | The ⋮ menu on the number’s Call Details | Call settings, on brands that have it | Its own screen, number typed or pasted |
| Tries and gap | 3, 5 or 10 tries; 10, 20 or 30 seconds apart | A few tries, fixed by the brand | Usually adjustable |
| How long each try rings | 30, 45 or 60 seconds, your choice | Until the network drops it | Varies by app |
| Knows the call was answered | Yes, from the call log, then stops | Stops when a call connects | Varies; some keep going |
| What is kept afterwards | Every try in the number’s call history, beside its lead record | The phone’s call log only | Usually nothing |
| Calls a list again | Yes: Call again if not answered, on any list | No | No |
| Best for | A business phone that also chases a busy line | An occasional busy number | Someone who only ever needs redial |

If redial is the only thing you will ever need, a single-purpose app does the job. RMDialer earns its place when the same phone also calls customers: the busy supplier line and the sales list sit in one app, on one SIM, with one history.
Real businesses, real numbers: how owners and sales teams across India and 12+ countries use RMDialer every day.
“Hindi mein app chalta hai, yeh sabse badi baat. Season shuru hone se pehle 400 kisaan ki list auto dial ho jaati hai, aur jo bole "baad mein call karna" uska reminder set. Excel se auto call kaise kare, yeh Google pe dhoondh ke yahan aaya tha. Ab do saal se use kar raha hoon.”
“GST and ITR deadlines mean 200 client calls in a fortnight. The auto dialer runs the list, the remark goes on the client's number, and the ones who said "documents by Friday" ring the assistant on Friday. A follow up reminder app that lives inside the phone dialer is the only kind my staff will keep using.”
“Collections calling is volume work. The auto dialer clears 250 numbers per executive per day from their own SIM, promise-to-pay dates become reminders, and the daily call report shows connected versus not reachable per person. Talk time per employee ended the "phone was busy all day" excuse.”
“Quote-and-chase business. Every enquiry gets a quote remark and a call-back reminder, and the ones we lost show up in the lost leads list for a discount call next month. Auto WhatsApp sends the quote PDF after the call. Would like a Telugu voice note feature, otherwise very good call management app.”
“Free telecalling app search brought me to the 3-day trial. Whole app, nothing locked. By day two I had imported last year's 1,200 travellers and the auto dialer was calling them for this season's packages. Paid the yearly plan on day three. The WhatsApp itinerary goes out after each call by itself.”
“Most CRM tools here are built for a desk. Our brokers sell from their phones, so a telecalling CRM inside the dialer made sense. Leads from Facebook ads land in the app, the auto dialer calls them, and the tripping schedule rings each broker. Tagalog interface, own Globe SIM, no VoIP number for clients to distrust.”

A different job with its own setting in the list dialer, so it gets only a short note here.
Auto redial chases one number. A list of customers needs something gentler: each person who missed the call gets another ring or two later, while the rest of the list keeps moving. RMDialer does that with a list setting called Call again if not answered, which stays off until someone switches it on.
Every option of that setting, the timings that suit sales lists, and what happens to waiting retries when a session is stopped are set out on auto dialer with redial.
A second pass at a different hour is still the strongest retry for customers. Filter the list by No Response, choose how long ago they were last called, and start a fresh session in the afternoon on the ones the morning missed. The list dialing that makes this possible is described on the automatic call dialer page, and for a team that runs it on its own numbers, on business auto dialer.
Short answer: not the Android way, and the reason is Apple’s, not the app’s.
Two things make redial work: placing a call without a tap each time, and knowing whether the last try was answered. iOS allows neither to an app. An iPhone app can open the dial screen for you to press, and it cannot read the call log afterwards, so it has no way to tell a busy tone from a conversation.
The RMDialer iPhone app has every feature except the call log, so an owner on an iPhone still sees the team’s calls, leads and reminders. Auto redial, like the list dialer, runs on the Android phones.
An illustration with round numbers, built to show the two kinds of redial, not a customer story.
Picture a small tour operator in Haridwar during the pilgrim season. Two people take enquiries for bus trips to the hill shrines, and every seat depends on one bus operator whose booking line is engaged from nine in the morning. Until now someone stood by the phone pressing redial between enquiries, and lost the enquiries in the meantime.
On the busy booking line the owner opens the operator’s number and starts Auto redial with 10 tries, a 30-second gap and a 45-second ring. The phone keeps trying in the background, and on the sixth try the line connects and redial stops. The seats are confirmed and noted on that number’s record, with a reminder for the payment date.
The enquiry list is the other half. Pilgrim families often miss the first call because they are travelling, so the morning list runs with Call again if not answered set to two more tries after the list. The dharamshala owners and families who were driving pick up on the second pass, and nobody is rung twice inside a minute.
Three cases where redialing does more harm than good.
People type "auto redial android" when they already know the phone, "auto redial call" when a line has been engaged for an hour, and "auto redial app download" when they are ready to install. All of them land on the same sheet in RMDialer, opened from the number’s Call Details. "Auto redial apk" is the same hope from someone used to sideloading; install from Google Play instead.
Four neighbouring questions have pages of their own: how to judge the best auto redial app, how a list gets its no-answers rung again on an auto dialer with redial, what works on an iPhone, and the meaning in Hindi on auto redial kya hai.
You will also see it called auto redial android, auto redial app download, auto redial apk and auto redial call. They describe the same thing, so whichever phrase brought you here, this is the page for it.
Find it in the call log, tap it to open its Call Details, and choose Auto redial from the ⋮ menu at the top.
Redial stops by itself the moment the call is answered. When you hang up, a short sheet saves what was said.
Put a date on the promise, and the reminder rings on the day. The tries and the answered call stay in the number’s history.
RMDialer is on Google Play for Android 8 or newer; the download page has the link. Auto redial on one number is free. Redialing a whole list is part of list auto dialing, on the plan after a 3-day trial; plans are on pricing. Prices are per user, exclusive of taxes.
For a phone that is also used for business, RMDialer is the best auto redial app for Android: it redials one busy number 3, 5 or 10 times, lets you choose the gap and how long each try rings, stops the moment someone answers, and keeps every try in the number’s call history. Auto redial itself costs nothing.
In RMDialer, open the number’s Call Details from the call log or your contacts, tap the ⋮ menu at the top right and choose Auto redial. Pick the number of tries, the gap and the ring time, then tap Start auto redial. A bar at the bottom of the app shows the redial running and lets you stop it.
Yes. Several single-purpose redial apps are on Google Play, and RMDialer, a full business dialer, has Auto redial built in. The practical difference is what happens after the call connects: RMDialer keeps the tries and the call in the number’s history and lets you save a note and a reminder on the same screen.
Some Android phones have a redial option in their own call settings. If yours does not, install an auto redial app: in RMDialer it is on the ⋮ menu of any number’s Call Details. Set the tries and the gap, start it, and the phone redials by itself until the call is answered or the tries run out.
Not one that works like the Android kind. An app on iPhone cannot place calls in the background or read the call log, so it cannot tell whether a try was answered. The RMDialer iPhone app carries every feature except the call log, and redial depends on the call log, so for Auto redial use RMDialer on an Android phone.
Auto redial means your phone calls the same number again by itself, again and again, until someone answers or the number of tries you allowed runs out. It is for a line that is busy or not answering, such as a helpline or a booking counter, and it is different from an auto dialer, which calls a list of different numbers once each.
Redial automatically ka matlab hai: phone khud usi number ko baar-baar lagata rahe jab tak koi call utha na le. Busy helpline ya booking line ke liye kaam ka hai. RMDialer mein number ki Call Details kholo, ⋮ menu mein Auto redial chuno, kitni baar lagana hai aur beech ka gap set karo, aur Start dabao.
Yes. Auto redial on one number is part of the free dialer. Calling a whole list again with the call-again setting belongs to list auto dialing, which is in the plan at ₹159 per user a month on yearly billing in India, after a 3-day trial with every feature.
As many times as you choose on the sheet, 3, 5 or 10, and never more than 10. It stops earlier the moment a try is answered, and when every try is used you get a note saying there was no answer after that many tries. Apps that promise to call a number 100 times are built for something else: ten tries is enough for a busy helpline, and past that the person on the other end is simply not answering.
After each try it reads the phone’s own call log and looks at the talk time of that outgoing call. Talk time means someone answered, so redial stops. If the call log cannot be read, the app treats the result as unknown rather than as unanswered, so it never rings back a person who already picked up.
Yes, but not with Auto redial, which works on one number. The list dialer has its own setting for it, Call again if not answered, that gives each missed person a limited number of extra rings at a pause you pick, without holding up the rest of the list.
No, one at a time. If a list session is running, RMDialer asks you to stop it before starting Auto redial, so two automatic sessions never fight over the same phone line. Finish or stop the list, redial the busy number, then carry on with the list.
Be careful. Auto redial suits helplines, booking lines and service numbers. Ringing a person again and again can feel like harassment and gets business numbers reported as spam. For a customer, use the list rule with a pause of 30 minutes or after the list, or call again at a different hour.
Install RMDialer only from Google Play. Copies of apps offered as APK files on other websites can be modified, and a file offered under the RMDialer name outside Google Play is not ours. Play also keeps the app updated, which matters for a feature that reads the call log.
Yes. The redial tries go out through the SIM your dialer settings use for calls, the same as your other auto dial calls, and each try appears in the call log with its SIM. Check which SIM is set before redialing a line that only answers calls from a registered number.
