HeartKeep is a no contact tracker without a subscription: one quiet day counter, a garden that grows with every day you keep, and a journal for the texts you will never send. It counts days, not check-ins. It remembers the dates that hurt before they arrive. No account, no AI chat, nothing leaves your phone. One optional one-time purchase. AT A GLANCE • What it is: a private breakup recovery app. A no-contact counter honest about slips (a slip lands on the days you kept, never on a zero), a one-minute daily check-in, a journal with unsent letters, milestones for every month, and a garden that grows as you heal. • For: anyone getting over a breakup or divorce, including the middle where it is not over and not okay. • Price: free. One optional one-time Plus purchase for exports. No subscription, no ads, no AI chatbot. • Privacy: 100% on your iPhone. No account, no server, no tracking. Works offline. • Languages: English, German, French. Made by one person in the US. NO CONTACT, COUNTED PROPERLY - The count starts the day you last had contact. Messages, calls, and looking at their pages all count - Slipped? Log it and land on the days you kept: "41 of 44 days kept". One text is a lapse, not a relapse - Two ways through an urge: Remember why cuts the pull and can sting; Change the channel lifts the mood now. The wave button offers both and says which does what - Four minutes, out loud: at three, six and nine weeks, talk about the breakup to no one. Nothing is recorded. It is the one exercise shown to rebuild who you are WHEN IT IS NOT OVER AND NOT OKAY Most breakups are not a straight line. HeartKeep is the first breakup app honest about that middle. - It's complicated mode meets you where you are, with no streaks and no judgment - Log contact as it happens: who reached out, and how it felt after - The Mirror shows your patterns back: contact days, quiet days, mornings after - HeartKeep reflects, never advises. The goal is your clarity, whatever you decide A GARDEN THAT GROWS AS YOU HEAL - A new plant takes root for every stretch of healing you get through - Widgets that grow instead of count: your plant under a sky that follows the clock. A word to hold, or today's verse, as a widget too THE DAYS THAT HIT Their birthday. The anniversary. The holidays you shared. HeartKeep holds these dates and is there the evening before, the morning of, and the day after. A NEW CHAPTER, WHEN YOU'RE READY - When you start needing the app less while feeling better, HeartKeep names it instead of pulling you back - Built to let you go well A DAILY CHECK-IN, IN UNDER A MINUTE - Slide to how you feel, then name it if you want. The words follow your mood: six at a glance, more a tap away A JOURNAL THAT MEETS YOU WHERE YOU ARE - Gentle guided questions for every stage: grief, anger, self-worth, letting go, and what comes next - Unsent letters: say everything you never got to, without sending it - "Text them, into the void": feels like texting them, never sends SUPPORT FOR THE HARDEST MOMENTS - "Before you reach out": a grounding moment for when you want to text them - A calming 4-7-8 breathing exercise, and prep for hard dates like the anniversary - On the darkest nights, call or text a real person from right inside the app OPTIONAL FAITH & STRENGTH - If it helps you, turn on a daily Bible verse and a quiet space to pray. Off by default TRULY PRIVATE, NEVER LOST - 100% on-device. No account, no server, no tracking, no ads - Optional Face ID / passcode lock - Free backup and restore, photos included HEARTKEEP PLUS (optional, one-time) Everything you need to heal is free. Plus is a small one-time thank-you that unlocks export: a PDF keepsake of your journal and a CSV of your check-ins. No subscription, ever. HeartKeep is a personal self-care tool, not a substitute for professional help. If you are in crisis, please reach out to a qualified professional or a crisis line such as 988 (US).
