Tumblr

Social blogging platform with ads

Overview

Tumblr is a social media platform for creating and sharing blog-style content. It lets users post text, photos, quotes, links, chats, audio, and video on personal blogs. When you follow a blog, its posts appear on your dashboard, and you can reblog posts with your own add-ons to share with your followers. The service is funded mainly by advertising, plus premium themes and customization options for blogs, while keeping core posting and browsing free. This makes it easy for individuals, artists, writers, and small businesses to express themselves and connect with others with similar interests. Tumblr differs from larger networks by emphasizing individual blogs, a strong reblog/share culture, and media-rich, easily customizable pages. The goal is to provide a free, accessible space for creative expression and community building, supported by ads and premium features.

Unforgetful is a brand new reminders app for individuals who cannot cease hitting snooze. Last updated: August 14, 2026 11:18 am Published: August 14, 2026 Marco Arment, the indie developer who created common apps like Overcast and Instapaper, and who beforehand served as Tumblr's chief know-how officer, is out immediately together with his newest creation - a substitute for Apple's Reminders designed for procrastinators, referred to as Unforgetful. The brand new iOS and Mac app works along with your present Reminders database, but it surely's designed for individuals who discover Apple's system doesn't work for them. As Arment explains in his announcement on Friday, "Siri, for all of its faults, has at all times been excellent at creating duties in Apple's Reminders app... The Reminders app, although, doesn't match me in any respect. I don't like the way it appears, the way it works, or the way it's organized. Hell, I don't even like its icon. There's nothing about it I like. So I by no means open it." The developer pointed to particular points the place he felt Reminders fell quick, like how its snooze characteristic labored, or these instances when he by chance dismissed a reminder as an alternative of snoozing it, dropping the reminder altogether. Arment additionally famous that if he forgot to incorporate a time when setting a reminder, he'd miss getting a notification, so the duty by no means acquired performed. Unforgetful is supposed to deal with these points and make it unattainable to lose your duties. For some, the answer might be overkill, however for many who are hooked on snoozing reminders or want extra common nudges, it may assist preserve them on observe. For starters, notifications will at all times repeat - even for those who miss them or dismiss them - till the duty is definitely performed and deleted.

The app retains issues pretty easy, too, as there aren't any tags, completely different views or modes, or different group instruments to study. (For extra superior options like this, Apple's Reminders app would nonetheless be a better option.) Briefly, Unforgetful turns into the software that makes certain you keep on high of your reminders, regardless of whether or not you like to enter them by hand or inform Siri, and regardless of whether or not they have a deadline or not. As a result of the app works along with your current Apple Reminders, you may proceed utilizing reminders as you at all times have - you simply flip off the Apple Reminders notifications and exchange them with Unforgetful notifications as an alternative. Whereas there are different well-designed, third-party reminders apps available on the market, the most effective factor about Unforgetful's setup is that this Reminders integration. This implies you don't must explicitly inform Siri to make use of Unforgetful once you're including reminders. And for those who discover you don't just like the app, you gained't must export your reminders again to Apple's database. (As a result of they're already there!) Unforgetful additionally ships with its personal in-app microphone for voice reminders and a full suite of widgets for the Lock Display and Management Middle.
