🇺🇸 It's been exactly one year since we went live with our Reproducible Builds publicly. Almost exactly at their first anniversary, we passed the mark of 50% apps covered by them.

But more has happened since: we've improved on the RBs, published the framework. You've asked for Download Statistics? Today we make those public. And more – plus more to come. As usual, we announce what it's ready – no fabulous promises, just facts. So read the full update here:

News from the first half of 2025: RB work, Download Statistics, and more

Half a year has passed since our last blog post. You might be curious what we achieved since then – and we have not been idle! Be prepared for more reproducible builds, download statistics, and other nice things 😃

@olikilo Funny, I gave a presentation about mobile privacy at work this year ;)

I think realistically, hiding completely is impossible. However, you can regain a lot more privacy by using private Open Source Android apps from #IzzyOnDroid and #FDroid instead of closed source apps filled with trackers. I personally recommend using Droid-ify as it is simple and preconfigures both IzzyOnDroid and F-Droid: apt.izzysoft.de/fdroid/index/a….

100K. One hundred thousand. That's a lot of #Catima users! And happy users, it seems, looking at that 4.5 star rating ❤️

Just, wow, I never expected my little hobby app to reach 100K active users, and that's just on #GooglePlay, still excluding other app stores like #IzzyOnDroid, #FDroid, direct downloads from #GitHub and sketchy app piracy sites (please don't use that last one, for your own safety 😅)!

Very cool :)

(3/2) Joe, Jane, Jerry, Jake: that's the line we build at #IzzyOnDroid. We run our "Janes" here to confirm "Joe's" builds – and we have "Jerrys" like Ben: independent builders. A builder is set up within 5 minutes thanks to codeberg.org/IzzyOnDroid/rbuil… – so everyone who wants can become a Jake.

@fdroidorg provides their verification builder setup as well, but that depends on the original builder providing the proof – so it only works with "source repos" like theirs and Guardian. Not independently.

Speaking of RB:

DavDroid 4.5.1 unfortunately failed RB. Which shows the thin line between "deterministic" and "reproducible":

We were able to build the app umpteen times, and got the very same, byte identical APK on each build: deterministic. So, it was reproducible, right? Well: no. It didn't match the APK built by the developer. A very slight difference in this case, an "off-by-one" in the baseline (so don't you worry, it's just the optimizer).
