None of it was in a form you could query.https://newagedevs.com/blog/dhaka-transit-data-nobody-could-query/https://newagedevs.com/blog/dhaka-transit-data-nobody-could-query/Every bus route, fare chart, train timetable and launch schedule in Bangladesh is public — as PDFs, scans and gazettes. This is how five of them became 2 MB of JSON that works with no connection, what it still gets wrong, and why every fare in the app carries a tilde.Wed, 23 Sep 2026 00:00:00 GMTProductWe made three video downloaders. Media Saver does all of their jobs.https://newagedevs.com/blog/one-downloader-instead-of-three/https://newagedevs.com/blog/one-downloader-instead-of-three/Instagram and Facebook in full, six more platforms, and any website through its own browser — including HLS streams.

The model was the easy part.https://newagedevs.com/blog/music-separation-on-a-phone/https://newagedevs.com/blog/music-separation-on-a-phone/Splitting a song into vocals, bass, drums and everything else runs comfortably on a laptop.
