Security & authenticity
Security rating: Unknown
Signing certificate
- Certificate issued to “WsDmrQx6328M” Not the developer's name (“Klimaszewski Szymon”). Names in certificates can't be verified, so this alone proves nothing.
- The same certificate signs apps from 4 different developers Developers normally sign only their own apps. This can mean the files were re-signed by someone else — or that one company builds or publishes apps under several names.
- Other versions use a different certificate v3.13.01. Android normally won't update an installed app with a file signed by another certificate, and a new certificate can mean a different publisher. v3.13.01
Store checks

Scans come from the source store; the certificate comparisons are AAPKs's own, made from the files' published signatures (1 other version compared). AAPKs doesn't scan files itself.
How to install Blood Pressure on Android 7.0+
You'll need about 10.1 MB of free space.
- Download the APK — tap Download APK above (5.1 MB). Chrome shows “File might be harmful” for every APK file; choose Download anyway only if you trust this file.
- Open the file — tap the download notification, or open Files › Downloads and tap com-szyk-myheart-999-72496065-9aaf8e8b7d33051e8dfd411f234e0562.apk.
- Allow the install (first time only) — Android 8 and later asks for permission the first time an app opens an APK: tap Settings in the prompt, turn on Allow from this source, then go back. Manual path: Settings › Apps › Special app access › Install unknown apps (on Samsung: Settings › Apps › ⋮ › Special access). On Android 7 and older: Settings › Security › Unknown sources.
- Check the file (optional) — the MD5 of the downloaded file should be 9aaf8e8b7d33051e8dfd411f234e0562. If it differs, the file is damaged or was changed: delete it and download again.
- Tap Install — Android asks “Do you want to install this app?”. This file has no malware rating from the source store. If Play Protect warns about it, tap Cancel. If an earlier version is installed, this one only installs as an update when it is signed with the same certificate (SHA-1 shown above).
- Open Blood Pressure — tap Open on the install screen, or find it in your app drawer.
Common install problems
- “App not installed” — a version signed with a different certificate, or a newer version, is already installed (Android doesn't allow downgrades). Uninstall it first; back up your data, because uninstalling deletes it.
- “There was a problem parsing the package” — the file is incomplete, or your Android is too old (this version needs Android 7.0+). Download it again, or pick an older version.
- Blocked by Play Protect — Play Protect checks apps from outside the Play Store. Only continue if you trust the source.
