TL;DR · SHORT ANSWER

What is the best automated calling app?

For list calling from mobiles, choose an app that dials on the handset SIM and records outcomes. Calling CRM does both and can switch the route to WhatsApp.

One app for dialling, follow-ups and WhatsApp: Calling CRM
Android-only team fed by marketplace leads: Dialmio
Planning to resell a dialler or use its API: RMDialer

The list

Best auto dialer app: the 7 apps, compared for hands-free list calling

Each entry looks at how much of a calling session the app runs by itself, from choosing the list to numbers that never answer. The order is our editorial call.

1
Calling CRM
callingcrm.in

Best for: teams that want the dialler, the follow-up alarm and WhatsApp inside one app.

A session can start from a filtered set of leads, an uploaded sheet, numbers from the call log, a caller’s assigned queue or today’s due callbacks. The phone then rings each number on its SIM, with a pause between calls that an admin can lock for the whole team.
Unanswered numbers come back for one to three more tries, a ring limit stops endless ringing, and a call that the network drops before it rings is placed again by itself. Read the full auto dialer app page for every setting.

Worth knowing: It places one call at a time. A large centre that needs several lines ringing per agent should look at a predictive dialler instead.

2
RMDialer
rmdialer.com

Best for: businesses that want a white-label reseller deal or a call-log API.

RMDialer bundles its list dialler with a telecalling CRM in a single plan that it says covers 67 features, with apps for Android and iPhone.

Worth knowing: Dialling from a computer and calling a list over WhatsApp are not mentioned on rmdialer.com.

3
AutoDial CRM
autodialcrm.in

Best for: callers who flip the same list between the SIM and WhatsApp.

Its site describes a list dialler that can run by SIM card or over WhatsApp, and says WhatsApp, Google Meet and Zoom calls show up in its call log next to ordinary calls.

Worth knowing: iPhone buyers are pointed to its support team for how list dialling works under iOS.

4
Telodial
telodial.com

Best for: small teams of two to fifty callers that want a reachable vendor.

Telodial lists SIM list dialling plus a WhatsApp calling mode capped at 20 a day by default, and can start a handset call from a number clicked in a Chrome tab.

Worth knowing: If you need recordings, note that it gathers the handset recorder’s files rather than capturing audio itself.

5
NLCaller
nlcaller.com

Best for: teams that lean on automatic retries and three-way calls.

nlcaller.com shows a list dialler with one to three automatic retries, click-to-dial from Chrome and conference calling, on both Android and iPhone.

Worth knowing: A WhatsApp route for list calling is not described on its site.

6
Dialmio
dialmio.com

Best for: Android teams whose leads arrive from marketplaces and ad forms.

Dialmio’s draw for list calling is where the numbers come from: marketplace enquiries and ad-form leads feed its SIM dialler and are dealt out to callers in turn.

Worth knowing: Android 8 or later only. The site says there is no iPhone app and no predictive dialling.

7
Telecalling Software
telecallingsoftware.com

Best for: office callers who want a plain dialler that keeps working offline.

The app at telecallingsoftware.com runs a list dialler and a lead list on each caller’s own SIM for Android 8 and later, with a web dashboard for managers.

Worth knowing: Its site says it does not ring several numbers at once and does not record call audio.

How we chose the best auto dialer app

Every app here dials from a mobile phone, not from a rented cloud line. We scored them on four things a caller notices within the first hour: where the call goes out, whether a list can also be rung over WhatsApp, what happens to numbers that do not answer, and whether iPhone users on the team are covered.

For the six rival diallers we relied on nothing but their makers’ pages and wrote not stated wherever a page stayed silent. Calling CRM is ours, hence the top slot; use each best-for line to weigh the others.

Best auto dialer app in India: a ten-minute trial checklist

Run a ten-number trial on your own SIM and count how many taps a caller makes between two calls.
Check whether the gap between calls can be locked, or every caller will set their own pace.
Ask what happens when a number rings out: retry later, retry now, or drop it.
Confirm which lists the dialler can start from, especially today’s due follow-ups.
If anyone on the team carries an iPhone, check what the iOS app can and cannot do before you buy.

Best Android dialer CRM: when dialler and CRM should be one app

On Android a dialling app can also take over as the phone app, which means the lead card can appear on every incoming call too, not only during a session. That is the case for a CRM with a dialer built in rather than two separate tools.

If your callers already live inside another CRM and only need numbers rung faster, a lighter dialler may be enough. If the outcome, the callback and the WhatsApp message should all be saved as the call ends, one combined app saves a lot of copying.

Can I move a lead list from one auto dialer app to another?

Usually, if the old app lets you export to a spreadsheet. Calling CRM takes Excel, CSV or JSON files and removes repeated numbers during the upload.
