No app store needed. It installs straight from your browser and works even with a weak signal at the job site.
On the phone you carry to jobs, open checkinsignals.com/app and sign in with the email your office invited you with.
Do this after you’ve signed in, from the app’s home page. Adding it from the sign-in page saves a shortcut to the sign-in page instead of the app.
iPhone (Safari)
Android (Chrome)
That’s the whole job. About a minute later the page is live on your company’s website — you’ll see it under “My pages”. A short walkthrough plays the first time you open the app.
On Android the steps are the same idea in Chrome: sign in, then ⋮ menu → “Install app”.
