Drill Architect is a website. Saving it to your Home Screen makes it open full-screen, like an app, without a download. Do this in Safari on iPhone, Chrome on Android — not inside Instagram, a group chat, or another in-app browser.
Open this site in Safari. Chrome and in-app browsers will not show the right Share sheet.
Tap Share — the square with the arrow pointing up, in the toolbar.
Scroll the sheet and tap Add to Home Screen. If you don’t see it, tap Edit Actions or the More row.
Name it Drill Architect if it isn’t already, then tap Add. The icon lands on your Home Screen.
Open this site in Chrome.
Tap the three dots in the top-right corner.
Tap Add to Home screen or Install app. Wording varies by phone.
Tap Add / Install. The icon lands with your other apps.
Samsung Internet: menu → Add page to → Home screen. Once it’s on the Home Screen, open it from there — not from a leftover browser tab — so it runs full screen.
