Years of scanned business cards and imported lists leave the same person stored three times over. Signal Recall finds them and walks you through fixing it — one decision at a time, with a way back from every one.
Free while in private beta. Nothing is changed until you choose a change.
In one real Hong Kong address book of 3,015 contacts, the first scan found 450 groups of duplicates and 1,828 numbers written inconsistently — in under a minute.
This app changes and deletes contacts. That is the whole point, and it is why every protection below exists before the first click.
Backed up on arrival
A full snapshot the moment you sign in, downloadable at any time.
Every merge undoable
The record as it was is kept for each change, so a wrong call costs one click.
Practise first
A copy of your contacts to work on before touching the real ones.
Nothing happens on its own
No background sync and no automatic clean-up. You click, or nothing changes.
Each one makes the next work better. Tidying numbers before matching is the clearest case: (852) 2198 1401 and +852 2198 1401 only match once they are written the same way.
Configure
Learns the shorthand you already use for companies, such as JPM or BOCHK, from your own contacts.
Tidy
Country-aware phone reformatting, names recovered from email addresses, and scanning damage repaired.
Merge
Field by field, side by side. You choose the record that survives and what to keep from each.
Fill in what is missing
Look people up on LinkedIn and elsewhere, straight from their contact card.
Every country’s numbers
Each number is read and written for its own country, rather than forced into one region.
Ting Ting stays Ting Ting
Reduplicated Chinese and Cantonese given names are names, not typing errors.
Family-first names keep their order
Chinese, Japanese and Korean names are left as written rather than rearranged.
Rules you can read and change
Every decision comes with its reason, and you can override any of it. Your contacts are never sent to an AI.
It reads your contacts and shows you what it found. Nothing changes until you say so.

That is expected while Signal Recall is in private beta. Choose Continue to proceed, without waiting too long or the sign-in expires. We only request access to your Contacts.
