Most habit trackers are too nice. Roast Monkey isn't. Meet Roko — the monkey who tracks your daily habits, builds your streaks, and absolutely drags you when you skip a day. Build habits. Break habits. And get the brutally funny feedback that finally turns 'tomorrow' into 'today.' WHY ROAST MONKEY HITS DIFFERENT • ROASTS THAT SCALE — three savagery levels (Mild → Medium → Send Help), so you set how hard Roko comes for you. • ROKO'S 12 MOODS — cool, angry, flexing, shocked, asleep, and more. Your monkey reacts to every win, miss, and excuse. • BUILD OR BREAK — track workouts, reading, hydration, meditation, walks, sleep, journaling, screen time, productivity. Or break smoking, doomscrolling, junk food, and late-night brain rot. • STREAK MILESTONES — unlock badges at 3, 7, 21, 30, 66, 100, and 365 days. Receipt-grade pride. • SHAME & FAME LEADERBOARDS — climb the Fame board with long streaks. Or land on Shame. Either way, your group chat will know. • SHAME A FRIEND — send a custom shame card when your bestie ghosts the gym. Best feature, no notes. • PRIVATE BY DEFAULT — no accounts, no cloud, no data harvesting. Your habits stay on your phone. WHO IT'S FOR • The 'I'll start Monday' crowd • Group chats that need accountability with vibes • Friends of 75 Hard, Atomic Habits, and 21-day challenges who need one more nudge • Anyone who can take a joke and wants to take their life seriously WHAT YOU CAN TRACK Workouts, runs, reading, journaling, meditation, hydration, sleep, screen time, diet, productivity, walking — or anything you type in. Set goals from 1 week to 66 days ('Stick It'). WHY IT WORKS Habit science says streaks plus identity equals behavior change. Roast Monkey adds the third ingredient: stakes that don't feel like homework. The roasts make missing memorable. The streaks make hitting addictive. Roko makes the whole thing feel like a friend who actually cares — by giving you zero slack. FREE TO START Build unlimited habits. Set streaks. Get roasted. All free. Premium unlocks deeper savagery and more (coming soon). Download Roast Monkey. Get your life together. Or don't — Roko's already got the receipts. https://www.vertexstudios.online/terms https://www.vertexstudios.online/privacy/roast-monkey
