3Sigma CRM is built mobile-first. Every feature — shared WhatsApp inbox, SIM auto-dialer, sales pipeline, quotation builder, live team tracking, 18+ reports — works from your Android phone. 50,000+ downloads. 4.6★ on Play Store.
Indian salespeople are on their phones. Their CRM should be too.
Arjun Nair is a solar energy salesperson in Cochin. He visits 3–4 sites a day, takes calls on his SIM while driving between them, WhatsApps proposals from a parking lot and creates quotations before he reaches the next customer. His previous CRM was a desktop app — he used it for 20 minutes in the morning and forgot it existed for the rest of the day.
With 3Sigma on Android, Arjun calls through the day's lead list on the auto-dialer (his SIM, no cloud cost), the CRM logs every call, he WhatsApps a brochure from the shared inbox and creates a quotation while standing in the customer's showroom. His manager sees every action in real time from his own phone.

Everything your sales team needs — on one Android app
Not a browser wrapper. Not a cut-down mobile version. The full CRM, designed for Android from the start.
Shared WhatsApp inbox
Your full team replies to leads from one verified WhatsApp number. Full chat history, chat assignment, filters and bot conversations — all in the Android app.
SIM-based auto-dialer
Dial your lead list back-to-back on your own SIM — any network, dual-SIM supported. The app auto-logs every call (duration, outcome, notes) without you lifting a finger.
Pipeline on your phone
Full Kanban and list pipeline with custom stages, deal value and drag-to-move. Swipe through your leads, update status in one tap, see the whole team's pipeline.
Quotation → invoice → WhatsApp
Create a quotation from your product catalogue, set line items, taxes and discounts, and share the PDF to the buyer's WhatsApp from the lead screen — 2 taps, done.
Live field tracking
Field agents check in from the app with GPS. Managers see the whole team live on a map — location, visit history, attendance — from their phone.
Caller ID on incoming calls
When a lead calls back, the 3Sigma caller ID shows their name, status and last activity on-screen before you answer — so you're never caught off guard.
18+ reports on mobile
Activity summary, call leaderboard, leads by source, user performance, sales funnel, task status — all available from the Android app, exportable.
After-call popup
The moment a call ends, a popup appears — set the lead status, add a label, write a quick note, schedule the next WhatsApp follow-up. The call becomes a CRM action instantly.
No other WhatsApp CRM Android app has a built-in SIM dialer.
Most WhatsApp CRM apps are chat tools — great for messaging, missing the calling half. Indian sales teams call and WhatsApp. 3Sigma puts both in the same Android app so every interaction — call, chat, quotation — lands on the same lead timeline.
SIM auto-dialer — your SIM, any network
Dial lead lists back-to-back using the agent's own SIM. Dual-SIM supported. No per-minute cloud charge. Crash-proof sessions resume from the exact lead if the app restarts.
100% auto-logged calls
Every call is logged automatically — duration, outcome, notes. Not a single call goes unrecorded, without the agent having to do anything manually.
WhatsApp follow-up from the same app
After a call, tap once to open the WhatsApp inbox and send a follow-up message. Call and chat history are on the same lead timeline — no switching apps.
Caller ID on incoming calls
Lead name, status and last activity appear on screen before you answer. So when Priya Sharma from Nashik calls back after 3 days, you know exactly who she is and where she is in the pipeline.

FAQs — WhatsApp CRM Android App
Is 3Sigma's WhatsApp CRM available as an Android app?
Yes. 3Sigma CRM is a full-stack CRM built mobile-first — the Android app has everything: leads pipeline, shared WhatsApp inbox, SIM-based auto-dialer, quotation and invoice builder, live team tracking and 18+ reports. It runs on any Android phone, any network, and is free to download on the Play Store.
What makes 3Sigma different from a desktop CRM on a phone browser?
3Sigma is built for Android from the ground up — not a desktop app squeezed into a browser tab. The SIM auto-dialer works on your phone's actual SIM (no cloud telephony bill), the caller ID shows lead name on incoming calls before you answer, and the after-call popup logs the outcome in one tap. The pipeline, inbox and quotation screens are designed for a 6-inch screen, not a 27-inch monitor.
Can the whole team use the app from separate phones?
Yes. Every agent logs in on their own Android phone. Lead assignment, pipeline stages and the shared WhatsApp inbox are synced across the team in real time. Managers see the whole team's activity — calls made, leads updated, pipeline status — from their own phone or from the web dashboard.
Does the WhatsApp CRM app work without a WhatsApp Business API?
Yes. With 3Sigma's WhatsApp Coexistence feature, you can connect your existing WhatsApp Business App number to the CRM — no new number, no losing your chat history. Your team picks up conversations in the shared inbox while you continue to use the WhatsApp app on your phone. WhatsApp Business API unlocks additional features like approved templates and bulk broadcasts.
Can I create quotations and invoices from the Android app?
Yes. From any lead's profile in the app, tap to create a quotation with your product catalogue and line items, add taxes and discounts, and share a PDF directly to the buyer's WhatsApp in two taps. Convert the quotation to invoice once accepted. All on your phone — no laptop required.
Does the auto-dialer work with dual SIM phones?
Yes. 3Sigma's SIM-based auto-dialer supports dual-SIM Android phones. You choose which SIM to use for calls. There is no per-minute cloud telephony charge — calls go through your carrier like any normal call.
