Meltek is a free service that rewards you for using less electricity during certain hours when energy is in high demand, and the power grid is under strain. Use your energy savings for cash, gift card rewards, charity donations, planting trees, or buying carbon offsets. – SAVE ENERGY, MAKE MONEY, HELP OUR PLANET! – Many electric utilities do not generate their own power. The cost of providing electricity can skyrocket during peak demand events, such as on the hottest summer days. Utilities, through Meltek, prefer paying you to reduce usage instead of risking blackouts. Join Meltek to reduce energy use, make money, and even help the planet. How It Works 1. Sign Up - Register with your electric utility info. Meltek tracks your energy usage and rewards reductions. Currently, we serve residents who use Con Edison, PSEG Long Island, Orange & Rockland or Rockland Electric Company as their electric provider. 2. Get Alerts - Receive alerts about energy-saving events in advance via app notifications, emails, or texts. This is your chance to earn by using less energy. 3. Reduce Usage - Before and during events, pre-cool your home, switch off lights, unplug devices, or delay using large appliances. The more you save, the more you make. 4. Get Rewards - Get paid by Meltek quickly* after each event. Transfer savings directly to your bank through Stripe. Or redeem them - the choice is up to you! Earn immediate bonuses by referring friends, family, or neighbors to join Meltek! *depending on utility; some of our partners currently prevent us from calculating rewards as quickly as we would like.

Most journaling apps fail because they ask too much. MonoLine asks for almost nothing. One photo. One line. Once a day. That's it. There's no blank page to stare at. No formatting toolbar. No folders or tags or organizational systems to maintain. You open the app, add a photo from your day, write a single line about it, and you're done. The whole thing takes thirty seconds. And then it compounds. After a week you have a week. After a month you have a month. After a year you have 365 moments—a grid of photos and the line you wrote beneath each one—that no highlight reel or social feed will ever give you back. What Makes MonoLine Different One entry per day, enforced: The constraint is the feature. You can't overwrite today or add a second entry. You show up, you write, you're done. Three ways to see your life: Feed view shows your entries chronologically. Grid view shows your photos as a visual archive. Both views let you tap any day to read what you wrote. Your streak, honestly tracked: A number in the corner of the app. No gamification, no pressure—just your record, kept honestly. Private by design: No ads. No AI reading your entries. No social features. Your journal is yours. Yours, with one purchase: No subscription. No trial countdown. No in-app upsells. You buy MonoLine once and it's yours—and with Family Sharing, the people you live with get it too. Export anytime: Download your full journal as JSON or Markdown. Your words don't live only in an app. For People Who Kept Abandoning Day One MonoLine is for the person who bought a beautiful notebook and filled three pages. For the person who downloaded four journaling apps and deleted them all. For the person who knows that one honest line beats a thousand words they never wrote. Start your first entry today.
