Open Settings → Back up to one file. Boxwright saves every box, your own drivers and your settings into one file and opens your phone’s share menu. Save it to Files, Google Drive, iCloud Drive, a computer or an email to yourself. I never see it.

Install Boxwright on the new phone, open Settings → Restore a backup and pick the file. It replaces what is in the app; you can undo right after. Then restore your purchase to get Pro back.

Open Settings → Restore purchases. Use the same Google account or Apple ID you bought with. A purchase on Google Play does not carry over to the App Store, or the other way round.

You can try Pro free for 7 days, once. It never turns into a payment by itself and there is nothing to cancel. When it ends, the Pro tools show as previews again. Every box stays: readable, editable and exportable.

Usually net against gross volume, a different port end correction, box losses, or a different version of the driver’s datasheet. The validation page lists each one, and how the engine is tested against Hornresp and published values.

Boxwright designs with net volume: the air inside after the driver, the port, bracing and any double baffle. The app keeps a ledger from the outside size down to the net, so you can see every litre that goes.

The app plays a slow tone through your amp. You watch the cone, or touch the dust cap lightly: at the box’s tuning the cone nearly stops while the port blows. You tap at that point. No microphone, no permission. The method is on the port tuning page.

Add it yourself from its datasheet; the input check tells you if the numbers do not add up. If you send me the datasheet link, I add it to the list in the next update.

Uninstall the app. Your data exists only on your phone and in backup files you saved yourself. See the privacy policy.
