Find every duplicate.
Trust every delete.

Last year I started making videos — teaching myself content production, shooting take after take after take. My iPhone was permanently full. Right when I wanted to film, right when something worth capturing happened: Storage Almost Full.

So I did what everyone does — I looked at cleaner apps. Every single one wanted $5–10 a month, or my data, or both. To delete files. On my own phone. We're all paying for enough subscriptions already — and if you're also paying for Tinder, honestly, that's expensive enough.

I've built software for 14 years. I grew up in India and have lived in Berlin for more than a decade, where I lead technology at a company. So I spent my evenings building the cleaner I wanted: one that runs entirely on your phone. No servers, no accounts, no data collection — which is exactly why it can be free. It costs me nothing to run, so it costs you nothing to use.

And one thing I can't ignore: back home in India, a lot of people pay for their iPhone in monthly installments — to banks, sometimes to money lenders. Someone who is still paying off their phone should not pay again every month just to manage its storage. Not in India, not in Germany, not anywhere.

DupFinder isn't magic, and it doesn't pretend to be. It does what's honestly possible on an iPhone: finds exact duplicates with mathematical proof, groups similar shots, scores blurry photos, compresses heavy videos. The rest is in your hands — and your photos never leave your phone, because there is nothing in this app that could ever send them anywhere.
