Foundry Drift is an idle factory builder that keeps ticking while it is closed, saves to a file you can export, and never asks you to watch an ad to speed things up.

About this app
Foundry Drift is an idle game about building a production line and then making it slightly less stupid. You place extractors, belts, and assemblers; the line runs whether the app is open or not; and progress accrues while you are away, calculated deterministically on resume rather than estimated. The interesting part is the bottleneck-finding, and the game gives you a proper throughput view rather than hiding the numbers behind a prestige curve. Prestige exists, it resets the line, and it is entirely optional.
It suits people who like optimisation and dislike the genre's usual monetisation, because Foundry Drift has neither ads nor a premium currency — no timer can be skipped with money, since there is no money in the game at all. Brightloop's stated position is that an idle game funded by ad-watching is designed to waste your time on purpose, and this one is priced once instead. If you want the dopamine cadence of a free-to-play incremental, this will feel slow, and that is a fair criticism rather than a bug.
A meaningful share of Foundry Drift's players run it on tablets and secondhand hardware without Google services, so Brightloop authorizes APKBrowse to host the stable APK directly. That download resolves through a short-lived signed URL and supports resumable byte ranges, which matters because the file is not small. The Play listing is still the simplest route for most people, and the artifact is byte-identical either way — the studio publishes one build and signs it once.
Before installing, know how the save works. Your factory is a single local file that you can export from Settings and re-import on another device; there is no cloud save and no account, so an uninstall without an export loses the line. Version 1.6.0 runs on Android 7.0 or newer, which is deliberately generous. The notification and boot-completed permissions exist so the game can tell you when a milestone completes and re-register those reminders after a reboot; deny them and the simulation still runs correctly, you just find out later. Rolling back to 1.4.1 installs cleanly on the same signing key, but 1.6.0 rewrites the save file to add belt-throughput history and 1.4.1 will refuse to open the migrated file, so export first.

Foundry Drift questions, answered
Is it safe to install Foundry Drift from an APK?
Yes, when it is the publisher-hosted download listed here, which Brightloop authorizes APKBrowse to serve. The file format is not the risk — the source is — so the practical rule is to install only builds whose fingerprint matches the value the studio publishes.
How do I verify the download is genuine?
Compare the SHA-256 of the downloaded file with the hash listed for that version here, which matches the checksum in Brightloop's public changelog. The signing fingerprint is identical across every Foundry Drift release, so a different signer means a different, untrusted build.
Will Foundry Drift work on my Android version?
Version 1.6.0 runs on Android 7.0 (API 24) and newer and ships arm64-v8a and armeabi-v7a binaries, which is deliberately wider support than most current games offer. It works on phones and tablets, with the tablet layout giving the throughput panels their own column.
Does progress really continue while the app is closed?
Yes, and it is computed deterministically when you reopen the game rather than approximated, so the numbers reconcile exactly. Nothing runs in the background draining your battery; the game simply replays the elapsed time against your line's throughput on resume.
How do I roll back to 1.4.1 without losing my factory?
Export your save from Settings first, because 1.6.0 migrates the file to add belt-throughput history and 1.4.1 will not open the migrated version. The install itself is unblocked since the signing key is unchanged, but you must uninstall 1.6.0 before installing the older build.

How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be com.brightloop.foundrydrift is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
If the current release misbehaves, 1.4.1 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall Foundry Drift first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of Foundry Drift, and a listing is removed when the evidence for it stops holding up.
