Open source projects refer to a software development model in which software developers expose their software source code and allow others to view, modify, and redistribute the code.

I find it interesting. There are quite a few cool source projects, such as FartHero, Tiimo, Zones, Hello and Cameron's World, etc. I feel they are all interesting and cool open source projects.

1. FartHero is an app that evaluates your farts.

It can analyze the decibel level of your farts and share your farts with your friends.

An Android version of Fartr has been recommended before.

So funny!

2. Tiimo This is a beautifully crafted calendar and to-do tool for planning to improve your daily life and reduce stress.

The main interface of the product is a visual timeline, where you can directly see an overview of the things planned for the day.

Plan your day's activities in the evening or morning.

Setting clear goals and doing them every day will increase your awareness of the things that matter most to you, and in the process you can also develop good habits.

Supports Android and iOS.

It has to be said that the functions of such tools are very simple, but how to make the product not bloated, simple and easy to use, and solve the specific pain points of users.

Understanding function trade-offs and designing according to user usage scenarios is a question worth thinking about.

Blindly stacking functions is uncompetitive in today's market.

3. Time zone conversion tool on ZonesiOS.

Different time zones can be tracked on iPhone, iPad and Mac.

The price is $2.99. This type of tool has been recommended before. It is a very simple gadget that is very suitable for buying out. It mainly has functions such as Menu Bar App, Reminders, synchronization with iCloud, and Widgets.

From the official website of this product, it can be seen that it is very simple, the product is very complete, and it is adapted to Apple Family Bucket equipment and is very comfortable.

4. Hello is a search engine for developers.

Search results can directly display relevant code snippets.

5. Cameron's World is a collection of website designs from the 1990s, an archive of thousands of such websites.

It's interesting to click on the links on this page, there are a lot of old websites.
