Most people don't quit energy drinks because they decide to stop. They quit because one afternoon the crash hits harder than the boost ever did. RushLess is built for that moment - and every one after it. Instead of demanding you go cold turkey, RushLess gives you a weekly allowance that steps down gradually toward your goal. Your body never hits a wall, so you never get the headaches and crashes that end most attempts by day three. TAPER, DON'T QUIT COLD Answer a few questions and get a personalized plan in under a minute — no account needed. RushLess sets a weekly quota from your real numbers and lowers it week by week until you reach your target, whether that's cutting back or stopping completely. THE 90-SECOND CRAVING RESET Cravings are waves. They peak and pass - you just have to outlast them. When one hits, one tap dims your screen and a guided breathing ring carries you through 90 seconds. Slipped anyway? We log the trigger, adjust your plan, and move on. No shame, no reset-to-zero. EVERY SKIPPED CAN BECOMES SAVINGS Choose something you actually want - headphones, sneakers, a trip - and RushLess puts the money you don't spend toward it. Watch your fund grow with every can you skip, with a live estimate of when you'll reach it. KNOW WHAT YOU'RE ACTUALLY DRINKING Scan a barcode or search a catalog of energy drinks across multiple markets to log exactly what you had - brand, size, and caffeine content. Drank half a can? Log half. Your favorites sit one tap away, so most logs take a second. STATS THAT TEACH YOU SOMETHING See your daily, weekly, and monthly caffeine intake measured against safe limits. Track your longest streak, cans avoided, yearly savings projection, and - most usefully - which triggers set you off most often, with tips built around your own pattern. STAY ON TRACK EVERYWHERE Home Screen and Lock Screen widgets keep your streak and weekly budget in view. On Apple Watch, log a drink or start the 90-second reset from your wrist. Gentle daily check-ins and milestone alerts, never nagging. EARN YOUR MILESTONES Badges at 7, 14, 30, 60, 90, 180, and 365 days. Share your streak as a designed card when you want to show it off. Light and dark themes. Multiple currencies. Your data stays on your device.

The clearest difference is iOS requirement: RushLess at 16.4 against Caffeine App's 18.0. On price, ads, in-app purchases and device support there is nothing between them.
