Scale the whole batch, not each line
Enter one target output and BatchRatio recalculates every component and the estimated batch cost on your device.
Reusable templates
Save component names, base quantities, units, and unit costs for the work you repeat.
Instant scaling
Change the target output and see each required quantity and scale factor immediately.
Useful exports
Share a CSV with the free version. BatchRatio Pro Lifetime adds unlimited templates and printable PDF exports.
Private by design
Templates, costs, and exports remain on this device unless you choose to share a file. There is no account, analytics, tracking, advertising, cloud sync, backend, or external processing service.
One-time Pro purchase
The free version includes up to three user-created templates and CSV export. BatchRatio Pro Lifetime is a non-consumable, one-time App Store purchase for unlimited templates and PDF export. Restore Purchases is available in Settings and on the paywall.
