MID-CENTURY MODERN MESSAGING Before emojis, before texting, before the screen — there was the punch card. MainframePunch turns whatever you type into an authentic keypunch card, punched column by column, with the clack of a real Hollerith machine. Send one to a friend and they hear the punches too. PUNCH CARDS RIGHT INSIDE MESSAGES — FREE Tap the MainframePunch icon in any conversation and punch a card without leaving the chat: Realistic Custom Card — classic manila stock, your words in real Hollerith code Mid-Century Color Card — the same encoding in period-correct pastels Ready-made cards — SEND COFFEE / ON MY WAY / SYNTAX ERROR / ABEND / CALL ME and more Every iMessage single card animates as it punches and carries genuine keypunch audio, so your recipient watches and hears the machine work. All of it is free. No account, no limits, no catch. THE OPERATOR'S CONSOLE Open the app for the full machine: Type or paste your message and watch the beam sweep across the card Stack up to seven cards into a single deck Export a Full Reel — a shareable video with synced punch audio Send along a Hollerith decoder card so anyone can read the holes (for education or to drive your friends crazy!) Adjust punch speed from deliberate to production line CORRECT DOWN TO THE HOLE Every character is encoded per ANSI X3.26 Hollerith — the same zone and digit punches an IBM 029 would have made in 1964. The sound is sampled from an actual keypunch machine, not a synthesized click. OPERATOR ACCESS Everything is unlimited for your first fourteen days. After that, punching cards in iMessage stay free, and an Operator subscription keeps the reel exporter running: Monthly — $2.99, with a 3-day free trial Annual — $19.99, with a 7-day free trial Already bought MainframePunch?

Verdict
The clearest difference is price: MainframePunch at Free against Blackie's $3.99. Blackie's advantage is update cadence (monthly vs every 12 months) and iOS requirement (10.0 vs 15.1). On ads, in-app purchases, monetization model and device support there is nothing between them.
