Your phone charges every night anyway. Wattnap turns those hours into points you can spend on real rewards. HOW IT WORKS • Plug in before bed. The session starts on its own, no need to keep the app open. • The longer you charge, the higher the rate: ×1.15 after 2 hours, ×1.3 after 4. • In the morning, tap Collect. Collect within 24 hours to keep every point. • Up to 9 paid hours a day. WHAT YOU GET • eSIM data that works in 160+ countries. Your first 250 MB pack is about a week of nights away. • Keep charging, keep getting data. Every night adds up to free roaming internet on your next trip. • Boosts that double your points for a day, and streak freezes for nights you miss. MORE WAYS TO GROW • Streak: every night in a row adds 5% to your rate. • Levels: each level adds 2% for good. • Missions: small daily tasks with bonus points. • Friends: invite friends and get a share of the points they earn. FAIR BY DESIGN Points are counted only from real charging. No ads in the app, no location, no contacts, no tracking across apps. Delete your account from your profile at any time. Points are a reward balance inside Wattnap. They have no cash value and cannot be exchanged for money.
