OSPOS is a free, open-source point-of-sale app. Now it runs on iPad too, laid out for a counter — and you can pair an iPad and an iPhone so they work as one register. Accept cash. Accept cards. No monthly fees. No contracts.
1.3 brings OSPOS to iPad, and lets an iPad and an iPhone act as a single register — one ringing the order, the other facing the customer.
A layout built for a counter: category rail down the side, menu grid in the middle, the running order always in view on the right. Nothing hides behind a tab.
Tap the items, take the money. Nothing to buy, nothing to sign.

Pair an iPad and an iPhone once with a four-digit code. The iPad rings the order; the iPhone faces the customer, mirrors the cart line by line, and takes the tap. Either device can be the register.
Every message between the two is signed.


An hourly chart on iPad shows you when the rush actually hit, with every transaction of the day listed underneath and cash counted separately from card.
Export any date range as CSV and hand it to whoever does your books.

No monthly fee. No minimum. No contract. No hardware to buy or rent. Cash sales are free forever, and card sales run through a Stripe account that belongs to you.
Cash register with menu builder, order tracking, daily summaries, and CSV export. No account needed. No internet required. Works completely offline. Zero dollars, zero catches.
You connect your own Stripe account and you keep it — a real merchant account, not a sub-account we control. Payouts go straight to your bank. Leave whenever you want; the account comes with you.
Tap to Pay on iPhone takes contactless cards, Apple Pay and digital wallets directly on the iPhone. Nothing to plug in, nothing to charge, nothing to replace when it breaks.
All data stored locally on your device. We never see your sales data unless you opt into cloud sync. No card numbers ever touch our servers. Open source — audit the code yourself.
Category rail, menu grid, running order. Built for a counter, not scaled up from a phone.
Pair once with a four-digit code. Either device can be the register. Every message signed.
Contactless cards, Apple Pay and digital wallets, taken on the iPhone itself. No reader.
Items with stickers, categories, and modifier groups. Customers customize, you ring fast.
Choose-your-milk, add-toppings, no-onions. Required vs optional, single vs multi, defaults that pre-fill.
86 an item or modifier mid-shift with one tap. Hides from the order grid without deleting.
Percent or dollar off the order with an optional reason, plus per-item tax that does the math correctly.
Hourly chart on iPad, date-range reports, cash against card, and CSV export.
Cash always works with zero internet. Card payments queue and settle the moment you're back online.
Stripe Connect Standard — the merchant account is yours. Payouts straight to your bank, no lock-in.
Email a receipt to your customer on the spot. Clean, branded, professional.
Get notified of chargebacks and submit your evidence directly from the app.
Two lines, and that's the whole price list.
Free forever. No account, no internet, no upsell at the end of a trial. Build your menu and ring up sales all day for nothing.
Card payments run through your own Stripe account, at whatever rate Stripe charges you — their published in-person rate is 2.7% + 5¢. OSPOS adds 1% on top of your Stripe rate, and nothing else.
Card payments are processed by Stripe under your own Stripe account; Stripe's own pricing applies — 2.7% + 5¢ is Stripe's published US in-person rate and is set by Stripe, not by us — and OSPOS adds 1% on top of it. Card payments are available in the US today. Requires iOS 16 or later. Tap to Pay on iPhone requires iPhone XS or later.
The math works hardest on bigger tickets — and on anyone who has no counter to put a terminal on.
Packages and add-ons, charged in the driveway.
Hook fee, mileage, winch-out. Paid at the scene.
Services per stylist, tips and rebooking at the chair.
Anyone who works out of a van instead of a storefront.
Take orders fast, rain or shine, with or without WiFi.
From farm stands to flea markets. Set up in a minute.
Modifiers, 86’d items, and a counter layout on iPad.
Small stores that need a register, not a terminal contract.
Download OSPOS, load a menu, and ring up your first sale. Free forever for cash. Card runs on your own Stripe account. No signup required to start.
