What's new in v1.1
Added 5th column, named Delta(R1, R2). For mobile phones it will be visible when holding the phone horizontically (landscape mode). For tablets it is always visible.
Delta(R1, R2) is the absolute value of R1 - R2. In mathematical terms it is abs(R1 - R2).
Users may need it it when searching e.g. for 2 parallel or serial sense resistors which values are as close as possible to each other in order to keep power dissipation in both resistors (almost) equally distributed.

How to install Series/Parallel Resistor v1.1 on Android API 8+
Takes about 2 minutes. You'll need roughly 1012.5 KB of free storage.
- Grab de.frank.schoofs.rparallel_3.apk — hit the Download button above (1012.5 KB). If your browser warns about APK files, choose Keep or Download anyway — that warning fires on every APK, not just this one.
- Trust your browser to install — on Android 8+ go to Settings → Apps → Special access → Install unknown apps, pick the app you downloaded with (Chrome, Firefox, Files, etc.), and flip Allow from this source. On older Android, toggle Unknown sources under Security.
- (Optional) Verify the file — compute the MD5 of the downloaded APK and make sure it matches 4e670d70e21d9898…. Any difference means the file is corrupted or tampered — delete and re-download.
- Open the APK — tap the download notification, or find de.frank.schoofs.rparallel_3.apk in your Files app under Downloads, then tap it. Android's package installer will appear.
- Check the signer — the install screen will name the publisher. For this build it should read CN=Frank Schoofs, L=Kleve, ST=Germany, C=D. If it doesn't match, cancel — you have the wrong file.
- Review permissions & tap Install — scroll the permission list, then confirm. If Play Protect flags it, tap Install anyway (this APK was scanned as TRUSTED).
- Done — open Series/Parallel Resistor — tap Open on the install screen, or find the Series/Parallel Resistor icon in your app drawer.
Common install errors for Series/Parallel Resistor
