How to install Numerical Methods Tools v1.2-free on Android 5.1 Lollipop+

Takes about 2 minutes. You'll need roughly 7.9 MB of free storage.

  1. Grab com.chatosolutions.numericalmethodstools_28.apk — hit the Download button above (7.9 MB). If your browser warns about APK files, choose Keep or Download anyway — that warning fires on every APK, not just this one.
  2. 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.
  3. (Optional) Verify the file — compute the MD5 of the downloaded APK and make sure it matches 4a4eee2c844550cc…. Any difference means the file is corrupted or tampered — delete and re-download.
  4. Open the APK — tap the download notification, or find com.chatosolutions.numericalmethodstools_28.apk in your Files app under Downloads, then tap it. Android's package installer will appear.
  5. Check the signer — the install screen will name the publisher. For this build it should read CN=Chato Solutions. If it doesn't match, cancel — you have the wrong file.
  6. Review permissions & tap Install — scroll the permission list, then confirm. If Play Protect flags it, tap Install anyway (this APK was scanned as TRUSTED).
  7. Done — open Numerical Methods Tools — tap Open on the install screen, or find the Numerical Methods Tools icon in your app drawer.
Common install errors for Numerical Methods Tools
