#252https://mergecal.org - First project I built when learning Django a couple years back. Takes multiple iCal feed URLs, merges them into one feed. Turns out people actually need this!
I almost built something like this a short time ago. Some devices/softwares (in my case it was the Supernote calendar app) only allow for one calendar as a source, and I had to merge my work and personal calendars to show up in my device. :)

#253My wife runs https://www.saviament.com/, an open-access educational website in Catalan. She also sells printable content following the same style as the website, which has exploded in popularity this year and has become a decent source of income.

#254I wrote a book about modern HTML & CSS to create website with as little javascript as possible.
I made almost 5k$ the first month, now I do 300-500$/month with it.

#255Back when I was in the Air Force, I hated the UX for referencing Air Force publications on mobile. So I created an iOS app called AFI Explorer [0] which has continued to get hundreds of downloads every month for the past 5 years.
Since I’ve been shifting more towards platform engineering work in my career, the best reward abut this side hustle isn’t the financial benefit, but is the opportunity to stay grounded in software dev. I love seeing the changing APIs each year with the new iOS updates. And the seasonal approach to doing updates is always fun too.

#257Just over $500 in subscriptions right now since posting on HackerNews and Reddit. This is mostly because of the posts gaining high engagement and people signing up and subscribing. Many also migrating from other apps. Expecting the revenue to go down next month https://onlyrecipeapp.com
Cool app but i feel 35$/year is a cost that is not justified for me, specially that i can extract the ingredients and the steps of any recipe from a video recipe in chatgpt, and then save it in notes.

#258https://cluesbysam.com I started making a daily logic puzzle called Clues by Sam in May and it's been stadily growing since. The number one thing people were asking for was more puzzles, so I started selling puzzle packs instead of monetizing with ads. The reception has been great, and the revenue has been enough for me to decline some consulting gigs and instead focus on improving the game.
I do Clues by Sam every day when I'm walking my dog before I start work, and I was particularly glad to have the daily mental workout this month, as I didn't have time for Advent of Code. Just bought both puzzle packs to support your great work!
I don't know how you're able to focus while walking the dog, but good job! And thank you!

#259I made a public transportation departure board (for Switzerland) for your home or business. https://stationdisplay.com/
This is pretty cool, can I ask why you decided to ship hardware and not a subscription to a dashboard that people could put on any mounted monitor?
Most likely because those dashboards are available for free from your local public transport operator.

#260I started my project in 2023 and posted here, made 20k that year. The traffic has been slowly decreasing during 2024, and last October, I was officially entering losing territory, where the cost of running it exceeded the total earnings (mostly due to free trials). It's been a good journey. Thank you so much to whoever keeps running this thread!
Just a small comment, as I don't know if you're planning to wrap up or keep maintaining the product...
I can't find the pricing of the product on the site, I only find that I get '10 free credits', but I don't know how much a credit is and what can I do with it.
Home page says it's one credit per diagram, but then the docs say it's a certain amount of credits per modification (that could be correct or not, I guess...)
I usually skip if I can't find the price, but it could also happen that people create the trial account, spends quickly the credits, then they find the price and it doesn't fit them. Of course, there's always people coming just for the free credits.
I don't know if this is helpful to you or not, but I hope so :)
