Thirteen best contact syncing apps for Android and iPhone.

1. Contacts

Download: Android iOS

The Contacts app is my go-to contact syncing app because it seamlessly integrates with my Google account, automatically backing up and syncing all my contacts across my phone, tablet, and computer – unlike other apps that often miss contacts or have syncing glitches. This ensures I never lose important contact information, a huge relief! Its intuitive interface and speed make managing contacts a breeze, plus the 30-day trash feature provides peace of mind. With billions of downloads and consistently high ratings, the Contacts app's proven reliability and widespread use solidify its superiority.

Key Features:

• Backs up contacts to the cloud.
• Keeps contacts synced across devices.
• Easily manages and edits contact details.

2. CoSy

Download: Android

Cost: Free (Free), Premium (One-time purchase) ($2.99)

CoSy is a handy contact syncing app for mobile devices that streamlines the process of updating contact photos by syncing them with Facebook profile pictures. While users praise its ease of use and the time-saving convenience of automatically linking contacts based on name similarity, some mention limitations with certain contact sources like Outlook. Despite this, the speed and efficiency of syncing images, even automatically on a daily basis, are major selling points. I chose CoSy because of its simple three-step process and its ability to quickly update my contacts with the latest profile pictures from Facebook, saving me the hassle of manual updates.

Key Features:

• Syncs Facebook profile pictures to contacts.
• Automatically updates contact images daily.
• Links contacts based on name similarity.

3. Contacts Sync (requires ROOT)

Download: Android

Cost: Free (Free), No other plans found (N/A)

Contacts Sync (requires ROOT) is a mobile contact syncing app offering enhanced contact photos by leveraging root access. This allows it to pull high-quality images from various folders, significantly improving contact identification during calls and within the address book, unlike standard apps which often display low-resolution or missing images. While offering a streamlined syncing process with customizable exclusions, its reliance on root access limits compatibility and presents potential security risks if not carefully managed. With over 127,000 downloads, it's a popular choice for users prioritizing visually rich contacts, but the root requirement should be carefully considered.

Key Features:

• Syncs address book with HQ contact photos.
• Automatic syncing, minimal user intervention.
• Selectively excludes contacts from syncing.

4. Contact Transfer

Download: Android

Contact Transfer is a contact syncing app that promises seamless transfer between Android, iOS, and PC, but user experiences are unfortunately mixed. While some praise its potential for streamlined contact management, others report frustrating issues like repeated payment requests, leading to accusations of being a "scam." Although it can successfully move contacts, the omission of notes during the import process ("Recomendo só não espere receber as anotações junto com a importava..") is a significant drawback. Ultimately, the decision of whether to choose this contact syncing app hinges on carefully weighing its potential benefits against the risk of encountering these reported problems.

Key Features:

• Effortless transfer between Android and iOS.
• Efficient contact management via PC.
• Supports adding, editing, and deleting contacts.

5. Shared Contacts®

Download: Android iOS

Cost: Free (Free), Premium (Unavailable. Pricing information not readily available on the Google Play Store page.)

Shared Contacts® is a mobile contact syncing app designed to streamline contact management across multiple devices and users. It boasts unlimited sharing capacity and seamless integration with Google Contacts, allowing for easy sharing of contact groups with colleagues, family, or friends (over 30,000 downloads demonstrate its popularity). While offering benefits like permission management (read-only, edit, delete, share) and synchronization with Outlook, a potential drawback is its reliance on a Google account for primary functionality. Ultimately, Shared Contacts® offers a powerful solution for collaborative contact management, but users heavily reliant on non-Google platforms may find limitations.

Key Features:

• Seamlessly share Google and phone contacts.
• Effortless group management and permission control.
• Synchronized contacts across all devices instantly.
