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, and one bank, project, and complete-device backup. Allowances count only after an operation succeeds.
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
No PunchKit account, ads, third-party analytics, or tracking. Optional iCloud Drive backup sync uses your Apple account. Other content stays local unless you share or export it. Diagnostic reports are sent only when you choose and exclude audio, sample and project contents, and filenames.
DISCLAIMER
PunchKit is independent and is not affiliated with or endorsed by Teenage Engineering.
PunchKit 1.11 brings optional iCloud backup sync, offline backup-library imports, and clearer restore compatibility guidance.
• In Backup, enable Sync Backups with iCloud Drive on each device using the same Apple account. Existing archives are copied and verified; local originals are retained. The library shows upload/download status and offers a download action for cloud-only backups.
• Turning sync off copies available cloud backups back to local storage without deleting cloud originals. Deleting an iCloud backup affects synced devices, but retained local originals remain independent.
• Add one or several PunchKit ZIPs or TE Sample Tool device-level PAKs to the backup library without connecting an EP. Original source files are kept, and duplicate filenames do not replace existing copies. Share archived files or connect an EP to restore them later. PAK sample preview is not supported.
• New project, bank, and full-backup manifests include source SKU when available. Cross-model and unknown-source restores require a separate warning and acknowledgement before Restore Anyway. You can back up the entire connected device first. Approval applies only to that restore attempt and connection session.
• Restoring native project data between different EP models is not verified and may leave the device unusable until a factory reset that erases all projects and samples. Choosing Restore Anyway does not bypass archive-integrity checks or PAK storage and write-protection checks.
• Project and bank switching now stops device playback first, avoiding active-target changes while the EP sequencer is running.
