About this app

Ohms Now! is a simple app that helps you decode resistor colour bands.

Simply tap on each band to change its colour. Once you have set all the bands to match your resistor's colours, you can then read its value in the text field below.

By long pressing on a band, a popup menu shows up to let you choose the band's color.

You can swipe left/right to go to the previous/next E series value.

When in 5 band mode, tapping the '6' icon in the top right will enter into 6 band mode. Tapping the icon (which will have changed to a '5' icon) again will go back to 5 band mode.

There is now ceramic capacitor decoding with all the same features (long press for list, swipe for values) as with resistors.

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.ktprograms.ohmsnow 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, v0.2.0-beta is the last build before it. Android will not install an older version code over a newer one, so you must uninstall Ohms Now! 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 Ohms Now!, and a listing is removed when the evidence for it stops holding up.
