Features
One app for your phone's most personal data.
Nkall replaces your dialer, contacts and SMS apps, and adds the tools you always wanted: spam warnings, reminders, emergency contacts, a Bin and restore.
All contacts, one list
Every Google, Microsoft and other account, phone storage, SIM and SD card in one list, with badges showing where each contact is saved.
Spam warnings
Suspected spam is flagged with the reason, worked out on your phone. Block hidden numbers and keep your own spam list.
Dual-SIM dialpad
Search contacts by number or name letters, speed dial on keys 2 to 9, a default SIM per key, and automatic retry on the other SIM.
Reminders that ring
Birthday and anniversary alarms at 8 AM, call-back reminders, and "remind me" right from a missed-call notification.
Emergency & family
Emergency contacts with a 3-second safety countdown, and family groups for one-tap calling from a home-screen widget.
Merge, restore & Bin
Find and merge duplicates, restore earlier versions of any contact, and get deleted contacts back from a 30-day Bin.
Nkall SMSYour default texting app
Messages & search

FAQ
Questions, answered.
No. Nkall has no NK Suite servers and does not use the internet. Contacts, call history and messages are read and processed only on your phone. Contacts go to a Google account or a file only when you start a backup.
Android only lets the default phone app show its own call screen, read the call log and block spam calls, and only the default SMS app can send and receive texts. Nkall asks first, and you can switch back any time in Menu > App Settings.
From your phone network. When the network sends the caller's registered name with a call (in India, the CNAP name), Nkall shows it for unsaved numbers. Nkall never looks numbers up on the internet.
Nkall checks your network's number verification, the caller name your network sends and your own call history, for example a foreign number you never called or a number that copies the start of yours. It shows the reason, and you can block or mark it as not spam.
Yes. Deleted contacts, even ones deleted in another app, stay in Nkall's Bin for 30 days. Restore Contacts also keeps the last 2 versions of every contact, so you can undo a change.
No. Emergency Contacts calls the people you chose, after a 3-second countdown you can cancel. In a real emergency, call your country's emergency number.
Your calls. Your texts. Your phone.
One private app for calls, contacts and SMS, with spam alerts and backups, and nothing sent to any server.
