ZiggSend vs LocalSend

Both check every file with SHA-256 (LocalSend since version 1.18). ZiggSend checks the whole file after it is written to disk, before it gets its final name, and that cannot be turned off; it keeps each file’s fingerprint in the history so you can check it yourself; it resumes big transfers from where they stopped; and it has a cable mode from Android to the Mac — all in the free plan with one phone. Pro only adds several phones, full history, automatic folders and up to 3 computers. If you never move anything you cannot afford to lose, LocalSend is enough.

Yes. Since version 1.18, on by default, LocalSend computes the SHA-256 of the bytes as they arrive and has the file sent again if it does not match (up to 3 attempts); the sender can turn off creating checksums and the receiver can turn off checking them. ZiggSend checks the file after it is written to disk, which also catches a write error, and only then does the file show up in your folder or gallery.

Yes. They do not conflict; ZiggSend uses its own port.

No. The privacy policy lists exactly what the app sends and when; your files and their names never leave your devices.

Install it on both devices (it is free: localsend.org and the app stores), open it on both on the same Wi-Fi, pick the other device in the list and send. If they do not see each other, allow it through the firewall on private networks. That is all — and it is why we recommend it for casual sharing.
