TodOne

TodOne is a simple to-do app for focusing on today. Only the few things today needs, laid out quietly — and you can add them just by talking to AI. Tired of to-do apps that keep growing? TodOne keeps the screen calm and lets the AI assistant take the fiddly parts off your hands. ■ Features 【Run your list by talking to AI】 "Add finish the slides for tomorrow's meeting." "How am I doing today?" Say it in plain words and the AI adds, completes, edits, reorders, searches and summarizes your tasks. No forms to tap through — today gets sorted in a conversation. 【Connect today to how you want to be (Vision)】 "Live healthier." "Hold a real conversation in Japanese." Register those as Visions and link your daily tasks to them, so you can see what today is actually for. Visions can be created and linked from the AI chat too, and in a check-in conversation the AI helps you put the current distance into words and turn the next single step into a task on the spot. 【Only today】 TodOne shows today's tasks and nothing else. No past or future noise — just what is in front of you. 【Home Screen and Lock Screen widgets】 See what is left of today without opening the app. Put it on your Home Screen, or on the Lock Screen before you even unlock. Tap to jump straight into that day's list. 【Send a task from anywhere】 Share to TodOne from any other app. An article you want to read, a note you want to keep — park it as one thing to deal with today, without switching apps and typing it again. 【Morning and evening reminders】 A quiet notification at the start and the end of the day: morning to pick today's few, evening to look back. Both times are yours to change in Settings. 【Carry unfinished work into today】 If something did not get done, TodOne tells you at the top of the screen. Pick from the sheet and move them into today together, instead of dragging tasks over one at a time. 【Activity log】 Every add, complete and edit is recorded. Filter and search by period or type to see how your days are actually going. 【Look back on a calendar】 Browse your past records on a calendar and see completed and unfinished days at a glance. 【Search everything you have done】 Search across all your past tasks by keyword, filter by completed or unfinished, and jump straight to the day you found. "Wait, when did I do that?" — answered in seconds. 【Note the outcome】 Leave a note when you complete a task. Recording what you did, and how, makes the handover to tomorrow's you far easier. 【English and Japanese】 If your device is set to English, TodOne starts in English. You can switch between English, Japanese and "match device" in Settings — screen text, date formats and even the AI's replies follow the language you choose. 【Easy from the very first launch】 The first launch walks you through a live sample: how to focus on today, and how to talk to the AI. You try it rather than read about it. ■ Privacy Your tasks are stored on your device. Only when you use the AI chat is your input sent to an AI service to generate a reply.

About

Relalog

Read full description

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.
