What is the best app to manage contacts?
The best app to manage contacts depends on who those contacts are. For friends and family, the Contacts app already on your phone, synced to a Google account on Android or to iCloud on an iPhone, does the job at no cost. For customers and enquiries, a plain address book falls short, because a name and a number say nothing about the last conversation or the next step. NLCaller, an Android and iPhone call management app, turns each saved number into a customer record: calls, remarks, follow-up reminders, WhatsApp chats and lead status sit on one screen, and the caller's name and last remark fill the call screen while the phone is still ringing. New callers can be saved as contacts on their own, 60 seconds after the call ends. As of October 2026, the contacts and CRM tools come with the paid plan at ₹162 per user per month billed yearly, plus GST, and a 3-day trial costs nothing.
Below, the options are sorted by what they are good at, followed by the questions worth asking before you move a business phone book anywhere. If your contacts are mostly sales enquiries, the lead management app page goes deeper on pipelines and statuses.
Which contacts apps belong on your shortlist?
Only one other calling app is named, and its facts come from its own website, checked on 3 October 2026. Remaining rows are kinds of tool, since the right pick depends on whether your phone book is personal or commercial.
| Option | Best for | Price checked | Watch out for |
|---|---|---|---|
| NLCaller | Sales teams, agents and shop owners whose contacts are buyers, on Android and iPhone | Free Basic Dialer for calling; contacts and CRM cost ₹162 per seat monthly on the yearly bill, GST extra | Contacts tools need a paid seat; on iPhone, the phone's own call log is out of reach |
| RMDialer | Someone who wants contacts, caller ID and spam screening in a free phone app | Free plan includes contacts; paid seat ₹159 per user monthly on yearly billing, tax extra | Free WhatsApp sends fall from 15 a day to 3 a day once the first 15 days pass |
| The phone's built-in Contacts app | Personal and family numbers on a single phone | Comes with the phone | No per-call remarks, no follow-up alarms and no sales status against a name |
| Google Contacts | One address book shared between an Android phone and a computer | Free with a Google account | A list of names and numbers, not a record of what was said or promised |
| A spreadsheet in Excel or Google Sheets | A one-off customer list that a few people edit together | Free or part of an office suite you already pay for | Nothing reminds you to call back, and copies of the sheet drift apart |
| Caller ID and spam apps | Putting a name to unknown numbers before you answer | Free tiers, with paid upgrades that vary | Read what the app does with your address book before you grant it access |
What should a contacts app do for a business?
A personal address book only has to find a number. A business one has to remember the relationship. Check for these before you choose.
- Name the caller before you pick up, using your own customer list first rather than a public directory.
- Save new numbers without typing. Enquiries arrive while you are driving or serving someone; a saved-later contact is usually a lost one.
- Keep the last conversation next to the name, so the next call starts where the previous one stopped.
- Ring you when a callback is due, instead of trusting a sticky note or memory.
- Find a person by anything you wrote about them, not only by the spelling of their name.
- Come back intact on a new phone, and keep personal numbers out of business automation.
How does NLCaller manage contacts?
Every point below is a shipped NLCaller feature. On Android it replaces the phone app, and your existing contacts and call history keep working as before.
- Caller ID checks your own leads, paid clients and contacts first, and numbers you have saved as leads or clients are never silenced, even when someone reports them as spam.
- Auto-save stores a new caller as a contact 60 seconds after you hang up, adding a prefix of your choice, and you can turn it off.
- Every contact has call, WhatsApp and SMS buttons, and the keypad searches contacts and leads as you type digits or letters.
- Any caller can become a lead with only the mobile number. Tag where the enquiry came from, add custom fields and leave a remark that pops up the next time you call them. The call log CRM page shows how this builds up from everyday calls.
- One search covers calls, contacts, leads, remarks, reminders, clients and chats, and each result opens as a full card.
- Backup keeps calls, leads, remarks and follow-ups in your account, so signing in on a new phone restores them. Numbers you mark as excluded stay out of backup and out of every automation.
How do you move your business contacts into NLCaller?
Most people are set up within one working session. The order below avoids typing anything twice.
- Ask for NLCaller on WhatsApp Send a message to +91 80184 88788 and the team replies with the app. It is not listed on the app stores yet.
- Make it the phone app on Android Set NLCaller as the default dialer so it can name callers and open the after-call sheet. The steps are on the default dialer guide.
- Turn on auto-save Pick a prefix such as your shop or brand name, so customer numbers saved by the app stand apart from personal ones.
- Import your existing customer list Bring in an Excel, CSV or JSON file, or connect a Google Sheet that is checked in the background. Duplicate numbers are dropped and country codes handled on the way in.
- Exclude personal numbers Mark family and friends as excluded so they are never backed up to the business account or messaged automatically.
What does this look like for a property agent?
A worked example, not a customer record. Picture a property agent in Pune with around 1,200 numbers in the phone. Roughly 300 are buyers and owners, saved under names like "2BHK Baner" or "Kulkarni site visit". In the phone's own Contacts app those labels are all the agent has when someone rings.
After moving to NLCaller, the agent imports the buyers' sheet once, marks about 200 family and friends as excluded, and lets auto-save catch new enquiries with the prefix "PR". When a buyer calls back, the screen shows their status (site visit done) and the last remark (wants east-facing, budget up to ₹90 lakh). The agent sets a reminder for Saturday from the after-call sheet, and it rings at that hour even if the phone is locked.
Sample notes from people who manage customer contacts on their phones
“Half my phone book was saved as plot numbers and colony names. Now the remark from our last talk comes up when they ring, so the odd name hardly matters.”
Property agent, real estate brokerage, Nagpur
“New buyers get saved by themselves a minute after the call, with the shop name in front. I have stopped typing numbers at the counter.”
Owner, mobile accessories shop, Cuttack
“I switched phones last month, signed in, and every customer came back with their remarks and pending reminders. There was nothing to export.”
Advisor, general insurance agency, Indore

When should you pick another contacts app over NLCaller?
NLCaller is built for contacts you sell to. Pick something else if:
- Your contacts are only friends and family. The free Contacts app on your phone, synced to Google or iCloud, is all you need.
- You want to organise contacts without paying. The Basic Dialer, NLCaller's free tier, is limited to calling, after-call WhatsApp and on-phone call analytics; contacts and CRM are paid.
- You need email newsletters or invoices sent from the same contact list. NLCaller does neither.
