Tomer Molovinsky breaks down six app design principles that make restaurant ordering apps sticky: visible primary action, easy reordering, visible rewards, clarity, familiar checkout, and passive personalization. Per Diem, a white-label ordering platform integrated with Square, bakes these into a product built for independent restaurants.
If you look at the most successful food and drink apps in the app store, Starbucks, Dunkin, Chipotle, they're not winning because of flashy design or clever features. They're winning because they've nailed a small set of design principles that drive habit, speed, and repeat behavior. These apps are built for real life. One hand, bad lighting. Customers are in a rush. They're hungry, they're distracted, and they want to order the same thing they ordered yesterday. So today I want to walk you through six design principles that consistently show up in the highest performing food and drink apps and why. We built Per Diem to make those same principles accessible to every restaurant, not just the giants. Principle 1 primary action is immediately visible the best food apps answer one question right away. What can I do for you? Right this second, in almost every top app, the answer is simple. Order, reorder. Pick up where you left off. There's no hunting, no clutter, no guesswork. At Per Diem, we design the home screen around the same exact idea. The app opens with a clear path to ordering where Whether that's starting fresh or reordering a favorite. No distractions, no competing calls to action. Because if a customer can't start an order with one tap, you're already losing them. Principle 2 Reordering beats browsing. Discovery is nice, but reordering pays the bills. Most customers are creatures of habit. Morning coffee, lunch bowl, Friday pizza. The best apps make reordering easier than browsing the menu from scratch. Recent orders and favorites are always front and center. Per Diem is built the same way. We surface past orders, save customizations and and favorites so your regulars can place an order in seconds. That's how you increase order frequency without discounts or promotions. Principle 3 rewards are always visible. Loyalty only works if customers can see it. In the best apps, points and rewards are never hidden behind menus. You open the app and immediately know where you stand and how close you are to something free. We designed Per Diem's white label apps in the same exact way. Rewards are visible on the home screen, during ordering and at checkout. That constant reinforcement nudges customers to come back one more time and instead of ordering somewhere else. Principle 4 Clarity over cleverness Top Feud apps are intentionally boring in the best possible way. Big buttons, clear labels, minimal copy, strong contrast. They're designed for speed and confidence, not visual experimentation. Per Diem follows the same exact philosophy. We optimize for clarity so customers know exactly what they're ordering, how much it costs, and where it's going. When people feel confident they complete orders. When they're confused, they abandon them. Principle 5 checkout should feel Familiar every time Checkout's where most apps lose people. The best apps keep checkout short, predictable and familiar. Saved payments like Apple Pay clear pickup or delivery details. No surprises. Per Diem's checkout is designed to feel the same every time, whether it's in app, web ordering, group orders, or catering. The goal is simple. Fewer steps, fewer mistakes, higher conversion. Boring. Checkout is a feature Principle 6 Personalization without setup the best personalization doesn't ask customers to configure anything. The app quietly learns time of day, location, order history. Morning items surface in the morning. Lunch favorites show up at lunch. Per Diem does this automatically across app and web. No merchant setup required. No customer friction. When personalization feels effortless, customers feel understood. The biggest takeaway is the best Food and drink apps aren't magical. They're disciplined. They prioritize speed over novelty, repetition over discovery, and clarity over complexity. The problem is that most independent restaurants don't have the time, team or budget to build this from scratch. That's exactly why we built Per Diem. Per Diem gives restaurants a branded mobile app and web ordering experience that applies these same proven principles out of the box. You get fast ordering and frictionless reordering built in loyalty that customers actually see. Clean conversion focused checkout personalization driven by real behavior. Deep square integration so menus, prices, and loyalty stay in sync. All without needing to design, develop, or to maintain it yourself. So to wrap it all up, the goal isn't to copy Starbucks. The goal is to give your customers the same level of speed, familiarity, and confidence they already expect from the best apps they use every day. That's what Per Diem is built to do. If you'd like, we can show you what this looks like for your brand and have a working version of your app ready literally the next day. Happy to walk through it together. Check us out at tripredium.
