What it does
The digital time capsule app. Write letters, diaries, and goals, lock them away, and open them when the time is right. Coming first to iOS, then Android.
Keepsule is a private time capsule app for letters, diary entries, photos, goals, and public memories that unlock later.
A private time capsule app for letters, diary entries, photos, goals, and public memories that unlock when the moment finally catches up. Remember how this felt: nervous, bright, a little impossible. Open this when you need proof that you kept going. Most apps pull you back into the present. Keepsule gives a moment somewhere to wait, so it can meet you again with distance. Capture the thought, promise, photo, goal, or private diary entry while the feeling still has texture. Choose when it should come back. Tomorrow, next year, graduation, a birthday, or a quiet milestone. When it unlocks, Keepsule brings the memory back with context, not just storage. Letters, diaries, goals, reflections,…from keepsule.co

Web app that lets you send email time capsulesDec 2025 · resurf.me · ▲44I had an issue where I would journal stuff, and then never look at what I wrote. So I thought it'll be cool to schedule something that will get sent to you at a later time (like a time capsule). Also, was inspired by futureme, where you can send yourself letters that'll arrive in the future.

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
