Relalog is a simple personal memo app that helps you easily record your interactions with people and manage them in timeline order. You can keep track of what you talked about, when you last contacted someone, and when you want to be reminded about important dates. Relalog is designed for relationships you want to remember, whether they are work contacts, friends, family, or people you meet through hobbies and everyday life. ■Organize notes by person You can save a person’s name, company, title, phone number, birthday, image, and tags. Each person has their own note history, so you can look back on past conversations and details whenever you need them. ■Manage interactions in a timeline Notes are saved with a recorded date and displayed in timeline order on each person’s detail screen. This makes it easy to review when something happened and what you talked about before meeting or contacting someone again. ■See when you last contacted someone Relalog shows how many days have passed since you last contacted each person. Color indicators help you notice recent contacts, people you have not contacted for a while, and people you may want to remember again. These colors are only a guide, not pressure. ■Use tags to organize people Create your own tags, such as Work, Friends, Family, or any category that fits your style. You can filter people by tags and quickly find the person you are looking for. ■Search quickly You can search by name, phonetic name, company, or phone number. Phone number search also works with or without hyphens and supports full-width numbers, making it easier to find saved contacts. ■Birthday reminders You can save birthdays for each person and choose your own reminder date and time. Birthday reminders work as local notifications on your device. ■Home Screen widget Relalog can show people with birthdays today on your Home Screen widget, helping you remember important dates without opening the app. ■Save and view images You can save an image for each person, such as a business card or a related reference image. Images can be opened from the person detail screen and viewed larger. ■iCloud sync After unlocking Relalog, your data can sync across your own iCloud-enabled devices. Sync uses your private iCloud database. ■No ads, even on the free plan Relalog does not show ads. The free plan lets you save up to a limited number of people. A one-time purchase unlocks unlimited people, iCloud sync across your devices, and Home Screen widgets. It is not a subscription. ■Privacy Relalog does not use ad SDKs, analytics SDKs, Firebase, our own server, AI processing, OCR, Contacts integration, or tracking. Your data is stored on your device or in your own iCloud account. For people who want to remember relationships without making things complicated, Relalog is a quiet and simple way to keep personal interaction notes.
