bentright — the free app that works offline
bentright is free, and so is the app. Install it once and every bending calculator and guide keeps working with no signal — in a basement, a crawlspace, or a new build with no wifi. No account, no app store, nothing to pay and nothing to update: it updates itself.
Checking this device…
You're already using the app. Nothing else to do.
On iPhone or iPad: tap the Share button (the square with an arrow pointing up), then Add to Home Screen, then Add.
Why install it
- Free, for good. No subscription, no in-app purchases, no trial that runs out.
- Works offline. Every calculator is saved on your device, so a dead spot on site doesn't stop you.
- One tap away. It opens from your home screen like any other app, with your most-used tools first.
- Private. Your numbers are worked out on your device and never leave it.
- Small. A few megabytes — about the size of a couple of photos.
iPhone or iPad
- Open bentright.com in Safari (it has to be Safari — Chrome on iPhone can't install apps).
- Tap the Share button — the square with an arrow pointing up, at the bottom of the screen (top right on iPad).
- Scroll down and tap Add to Home Screen.
- Tap Add. The bentright icon appears on your home screen.
Android
- Open bentright.com in Chrome.
- Tap Install the free app (the button above or at the bottom of any page) — or tap the ⋮ menu, then Install app (some phones say Add to Home screen).
- Tap Install. The bentright icon appears with your other apps.
Computer (Chrome or Edge)
- Open bentright.com.
- Click the install icon at the right-hand end of the address bar (a screen with a small arrow), or click Install the free app.
- Click Install. bentright opens in its own window and gets a desktop / Start-menu icon.
Check it works offline
- Open the app once while you have signal and wait a few seconds — the line at the top of this page says when everything is saved.
- Turn on airplane mode.
- Open the app and use any calculator. It works.
If a page ever says it hasn't been saved yet, open it once with signal and it's saved from then on.
Updates and removing it
There's nothing to update: when we add or fix a tool, the app picks it up the next time you open it with signal. To remove it, press and hold the icon and choose Remove (Android) or Remove App → Delete (iPhone). Nothing else is left behind.
