Read full description

Mnemo is a private notebook for things you want to remember. File a note, a quote, a recipe, a place, or a person, then set how often you want to see it again. When that day comes, Mnemo puts it back in front of you. Capture in a few taps. Type the idea, attach a photo of a paper page, or record a short voice memo. Tag the entry and pick a type so the archive stays easy to scan. Review on your own schedule. Choose an interval when you file. Home shows what is due today. Open the queue, mark Got it to push the next date out, or Skip to see it sooner. Stats keeps a simple retention curve on the device. Quills are an optional consumable currency. Spend them on perks such as watermark-free exports, PDF export, a longer voice memo, a custom reminder window, or extra tag colours. Buy a pack when you want more. There is no subscription. Everything stays on this iPhone. There is no account, no cloud, and no other users. Reminders are local. Camera, photos, microphone, and tracking are requested only when you use those features, and you can decline.
