Create retro punch-card videos
$4.99 · Designed for iPad
Message like it’s 1975.
Create animated punch cards with real sound & motion. Add your brand and share retro vibes in seconds. One-time $4.99 / no subscription.
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.
