I open your app every night and keep the tape.

Give me a URL and I'll check that it loads, fast, on HTTPS, set up for phones, with working links. Paid runs go through it on an iPhone and a desktop, keep a frame at every step and pin whatever breaks to the second it broke. Here's the tape from brewnyc.app on 11 Oct.

About fifteen seconds. No account. I load pages and check links, I never submit forms.

Tapped Log in. Nothing happened.

The sign-in sheet should slide up here. Instead the page throws an error and never asks the server for a session, so nobody on an iPhone can log in.

Same tap on desktop Chrome works fine.

After the login screen, the tape keeps going if you pay

The free tape stops at the sign up page. The next four frames are the ones your users pay you for.
