Add notes on calls

Remember what matters before you answer—and while you talk. Call Notes lets you attach a short, private reminder to a contact’s phone number and see it in the familiar iPhone calling experience when you make or receive a call. Add the cue once, then use your Phone app as usual. Prepare for a client call. Remember a friend’s big news. Keep a preference, promise, or talking point where it is most useful: right beside the call. WHY CALL NOTES • See a concise note on incoming and outgoing calls • Add notes to existing contacts or create new contacts • Save a different note for each phone number • Use one note across all of a contact’s numbers when you prefer • Search by name, note, label, or phone number • Call contacts directly from the app • Turn call notes off at any time without deleting them FOR WORK AND LIFE Sales professionals, consultants, founders, recruiters, account managers, and small-business owners can keep client context close. Friends and family can remember plans, preferences, milestones, and the small details that help people feel remembered. PRIVATE BY DESIGN Your contacts and call-note text stay on your iPhone. No account is required, and there is no contact-content cloud sync. Call Notes uses Contacts access to select or create contacts and place your note in the phone-number label shown by iOS. GOOD TO KNOW Call notes are short by design so they fit the call screen. A Contact Poster can cover the phone-number label; if that happens, Call Notes shows you how to remove the poster for that contact. Contact Posters themselves are never changed by Call Notes. PREMIUM Premium unlocks unlimited call notes and notes for each contact phone number. Choose monthly access or a lifetime purchase. Monthly access renews automatically unless canceled; you can manage or cancel it in your Apple Account settings. Restore Purchases is available in the app. Privacy Policy: https://sites.google.com/view/callnotesp/home Terms of Use: https://sites.google.com/view/callnotesterms/home EULA: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
