Petya

What opens from your phone — and why the rest doesn't

Petya checks websites and services right from your iPhone, shows how fast they answer and names the reason when something fails. When you need it, it turns on a VPN from your own subscription link.

What it does

Checks in seconds

A list of popular services: each is asked for its smallest file and the response time is measured.

A reason, not just “down”

No response, reset, name not resolving, address replaced, certificate error — every failure has its own name.

Me or them

Reference points — Cloudflare, Google and Apple — tell at once whether it's your network or the service.

History

Past results stay on your phone, so you can see whether things got better or worse.

VPN from your link

Add a subscription link from your provider — Petya loads the servers and keeps the connection up for you.

Connection log

If the VPN misbehaves, the log shows what happened — and you can send it to support as a file.
