Useful tools.
Made with care.

Fettle is an independent technology maker. We build tools that do a useful job, explain themselves clearly and leave you in control.

Starting with the apps on your Windows PC.

Your app updates.
A clearer view.

Bring supported updates, installed apps and update history together. Review what’s available and choose what happens next.

Open source. Unsigned 0.15.0 preview for testing.

A little more considered.

A check that tells you what it knows.: Incomplete information stays incomplete. It doesn’t become “up to date”.
Preferences that stay yours.: Ignore an app, skip a version or keep an update for individual review.
A result you can look back on.: The installer’s outcome and the verified version are recorded separately.

Care is in
what happens next.

A useful tool should make the next decision easier. That means clear choices, honest limits and attention to the details you meet every day.

Updater is open source. You can inspect how it works, see what still needs work and help improve it.
