PunchKit

Browse your EP and sample shelf together, perform with beat-synced cassette and Punch It effects, and enjoy smoother reconnects, backups, previews, and navigation.

FREE TO START, PRO FOR UNLIMITED WORKFLOWS PunchKit is free to download. Connecting, browsing, previewing, playing, sharing, renaming, deleting, restoring backups, and using existing files remain available without limits.

The free tier includes:

• Three successful take creations
• One local kit creation and one complete kit upload
• Three successful sample writes
• One stem separation
• One bank, one project, and one complete-device backup

Allowances are counted after an operation succeeds. Deleting or moving a take or kit does not restore a creation allowance.

One optional Lifetime Pro purchase removes these limits. There is no subscription, and Pro supports Apple Family Sharing. On iPhone and iPad, people who first downloaded PunchKit before version 1.3 receive Lifetime Pro automatically as founding users.

LOCAL-FIRST BY DESIGN PunchKit has no account, advertising, third-party analytics, crash-reporting SDK, or tracking. Audio and EP content stay under your control.

Issue reports are sent only when you choose. Optional diagnostics may include redacted app activity and Apple-provided crash information, but exclude audio, samples, project contents, and filenames.
