HeartNotes is a quiet, end-to-end encrypted app just for the two of you – for shared moments, small gestures, and real connection as a couple. No feeds, no likes, no distractions. Private by Design All content is encrypted directly on your device before it ever leaves your phone. Even we can't read it. You can also lock the app with Face ID, Touch ID, or fingerprint for extra peace of mind. Share Your Mood A simple daily check-in: how are you feeling today? Add a note, share what's on your mind, and gently let your partner know what you need. No pressure, no judgment. Send a Heart A press on the heart in the app – and your partner feels in that moment that you're thinking of them. A small gesture that often gets lost in everyday life. Photo of the Day (with HeartNotes Pro) A new theme every day. You both upload a photo and see them side by side – your take on the same day. React to each other and collect your shared moments. Love Letters as a Surprise Write messages your partner won't discover until later – in the next few days, in a week, or a few weeks from now. You choose the time window, the exact moment stays a surprise. "How Well Do You Know Me?" One question a day about yourself. Your partner tries to guess your answer. Discover something new about each other every day – even after years together. Your Relationship Chapters With every shared moment – every photo, every question, every letter – your chapter grows. A timeline of your moments, moods, and letters that gets richer every day. HeartNotes isn't an app that pushes you toward streaks or floods you with notifications. It's there when you need it – and stays out of the way when you don't. HeartNotes is free to use. With HeartNotes Pro, you unlock all features – available as a monthly or yearly subscription, cancel anytime.

Verdict
