What is the best Google Contacts alternative for Android?
Start with Contacts+ if you want Google, iCloud and Outlook in one book. Fossify Contacts if you want no account. DAVx5 if you sync to your own server.
Will I lose my people?
No. Contacts on the phone or in a Google account stay there. A new app reads the same book, or you export a vCard.
Can I go back to Google Contacts?
Yes. Open Google Contacts. People already saved stay there.
Is DAVx5 a contacts app?
DAVx5 syncs contacts to your own server. They then show up in Fossify Contacts or any other book on the phone.
Do I need an account?
Not for Fossify Contacts or OpenContacts. Contacts+ can use the accounts you already have.
