I learned the moon movements in schools, but almost forgot everything. So I built this small page, to track the moon. Moon also has rise and set everyday, and changes its position in sky dramatically everyday. Check it out if you also want to pick some knowledge up.

1 click to open frequently used links, or copy frequently used notes. Better than bookmarks, because: 1). Bookmarks are not real cross-devices, you have to use the same browser on all your devices, and turn on sync; 2). Most of your links are saved in bookmark folders, so it's hard to find; 3). Your links are not end-2-end encrypted before sending to their server; Simpler than clipboard...

How it started? It started with the question: how to backup my photos safely? Not iCloud/GoogleDrive/Dropbox etc: They don't encrypt my photos and notes, and there are always people who have the permission to view my files. Maybe they won't, but they can. Not encrypted drives: like ProtonDrive, Filen, Ente, because I also want to write some words for my photos. What I really need is...

We are so busy, that sometimes we forget the important things in life. We need to remind ourselves. And let's remind ourselves in different and fun ways: only notify me when this year passes 1%, or 4% or 12.34%; or the closer my wife's birthday gets, the more notifications I get; or randomly, sometimes I get notification in 8 days, sometimes it's 23 days; or notify me something that happened...

Need to share files across different devices, or with others? You have so many options to do so: all kinds of cloud storage, all kinds of messaging apps etc. But there are problems with them: 1. Your original files are saved in their servers. There are always people who have access to those files, and they can view your files if they want. 2. You need to create an account. With...

I have bought some PDFs from gumroad, but most are only in A4 format, which is super hard to read on phones. So I created MobilePDF to create mobile friendly PDFs. - Everything is end-to-end encrypted; - Create both mobile friendly PDF and normal A4 PDF; - Auto generate table of contents; - Add cover to your PDF; - Host your work in a website; I hope it can help you. Pay once, get life time...

Congrats! I will definitely use it

Let's take a small break in the age of AI. Encrypt37 protects your privacy, you don't need to trust no one. For contents that we want to share, we can share them via youtube, X, medium, tiktok etc. But for contents, like our diary, family photos, personal notes, they are private, then they should stay private, and they should be encrypted before leaving your laptop or phone. Never use...

Now you can enable 2FA for your account :)

I never enjoyed browsers' bookmarks So I build Link37 And I also believe you should control your data So everything is encrypted before sending to server

Early this year, I went to a small city in Germany to ski, but unfortunately it was too warm, there was no snow. On top of the ski website, there is a banner, giving updates about the status. But there is no option to leave my email there, to subscribe to the updates. So I checked the website everyday for several days. Then an idea came to my mind, I can build a bot that checks the website...
