Forget it so you can remember it. Tememo is not a typical to-do list app. It is a notification app that remembers all those “I’ll do it later” things for you without any tedious date or time input. ◆ What you can do with Tememo * A place where you can quickly jot down anything you plan to “do later” * Gentle reminders as many times as you need, at times that match your daily rhythm * Check and complete tasks right from notifications without even opening the app * Save web pages and images instantly via the share sheet * Use it on iPhone, iPad, and Mac — one place for all of them * Stored on your device, with zero ads for a stress-free experience If you’ve ever forgotten the very things you wrote down in a memo, this app was made for you. ◆ Eight features that let you forget with peace of mind * Task watch notifications Once you register a task, Tememo keeps an eye on it and sends you fixed-time alerts until you take action. It helps prevent those “I was supposed to do that” moments from slipping away unnoticed. * Fixed-time alarms that match your daily rhythm At lunchtime, after work, after waking up, before bed, and more— you can set up to five fixed times that suit your daily routine. Tememo only reminds you at times when you’re actually in the mood to look. * Lightning-fast entry Whenever you open the app, you’re greeted by a simple screen that’s ready for input. There’s no need to set a time; tasks are automatically scheduled for the next fixed-time reminder, so you can jot things down before you even start overthinking them. * Register items from outside the app in an instant Interesting web pages and screenshots can be sent straight into Tememo from your device’s share sheet or share button. With a single tap, you can put off things you want to read or check properly later. Home Screen and Lock Screen widgets show what is still waiting, at a glance. * One place, whichever device you pick up Tememo runs on iPhone, iPad, and Mac. Jot something down on whichever device is in your hand, and clear it on whichever one you sit down with. Turn on iCloud sync and every device shares the same list. * Piling up? No problem When too much has gathered, switch to triage and swipe the cards one by one. Today, later, or done — a minute is enough to clear the pile. * Fully private by design By default your data stays on your device, and everything through to notifications works offline. Nothing is sent to an external server, and there is no waiting around for loading. Only when you want to use several devices do you turn on iCloud sync, which stays inside your own Apple account. * No ads, no noise Even on the free plan, no ads are ever displayed. We don’t want anything getting in the way at the moment you’re checking an important task. ◆ Make it yours Set any photo as your background. Crop it, blur it, and outline the text until everything stays comfortable to read. Theme colors, dark mode, and display size (80–150%) are yours to choose too. ◆ Recommended for people like this ・You often forget your partner’s small requests ・You tend to drop “soft, low-pressure tasks” that don’t feel big enough for your calendar ・Things you intend to “do someday” somehow always end up being postponed Why not start by using Tememo as a private home for those “soft, low-pressure tasks”? It might be the little nudge that makes someone smile and say, “You actually remembered that.” ◆ Plans * Free Plan (free forever) All core features available Up to 20 tasks No ads (and none planned for the future) * Premium Plan (one-time purchase) Unlimited tasks Support the developer There is no subscription. You can use Tememo for as long as you like without worrying about forgetting to cancel anything. Let Tememo remember things for you. You just focus on the present moment.

Verdict
The clearest difference is update cadence: Diary Notes at every 4 days against Tememo's every 2 weeks. Tememo's advantage is device support (4 vs 2) and iOS requirement (15.6 vs 26.0). On price, ads and in-app purchases there is nothing between them.
