MainframePunch

MainframePunch turns your words into animated, authentic-looking computer punch cards—complete with classic hole patterns and satisfying punch sounds. Add your own brand caption, preview the animation, then record a crisp video to share anywhere. No accounts, no cloud, just retro messaging made simple.

What you can do:

* Create true-to-spirit 80-column punch cards with classic row/zone labels.

* Preview live with “Punch Cards,” or capture a video with “Record & Share.”

* Add a bottom caption (your brand or message) to every card.

* Toggle letters on/off above each column; reveal them as the holes are punched.

* Enjoy synchronized punch audio timed to each column.

* Flow long text across multiple cards automatically (up to 20 cards).

* See estimated card count and video length before you punch.

* Save a composite image of the stacked cards after a run.

* Adjust animation speed and card scale for the perfect look.

* Share using the iOS system share sheet (iMessage, Mail, social apps, etc.).

* Private by design: all processing happens on your device.

How it works:

* Type or paste your message in the Punch Contents box.

* Tap “Punch Cards” to preview—or “Record & Share” to export a video with sound.

* Share the result right from the iOS share sheet. That’s it.

Why it’s delightful:

* Authentic look & sound: the timing, holes, and motion feel like the mainframe era.

* Brandable: add a tasteful caption along the bottom of every card.

* Flexible: hide letters for a pure punched-holes look, or show letters as they appear.

* Fast: export a clean MP4 in seconds; no sign-in or servers required.

Great for...

* Geeky greetings, inside jokes, and team shout-outs.

* CS classes and museum demos (Hollerith encoding made visual).

* Creators who want a distinctive vintage look for Reels/Shorts.

* Tech culture moments—release notes, conference promos, easter eggs.
