Biniru Personal Toolkit
95 tools in one Android app. Camera, OCR, calculators, sensors, network, security, lab scanners, dev tools — all native, all offline-first, all in your pocket. No tracking, no ads, no in-app purchases. One paid app, full lifetime access.
01 What's inside
PTK bundles 95 small tools you'd otherwise install as 30+ separate apps. Most are 1-tap utilities (flashlight, ruler, QR scanner, calculator). Some are tools competitors charge a monthly subscription for (Yuka €12/yr, LastPass €36/yr, CamCard $5/mo). With PTK they're included in the one-time price, no subscription, no IAP.
Offline-first
Almost every tool runs without internet. Camera, sensors, calculators, vault, files — all device-side. The few that need internet (Speed Test, Food Scanner barcode lookup) say so explicitly.
No tracking, no ads
No Google Analytics, no Firebase, no Crashlytics, no ad SDK. Zero telemetry. Permissions only for what each tool actually does — camera tools ask for camera, GPS tools ask for location, that's it.
One-time, not subscription
€10 once. No "Pro upgrade", no "premium", no "unlock 5 more tools for €4.99". The whole 95-tool toolkit is yours, today and forever, on whatever Android you put it on.
Native Compose, not webview
Everything is Kotlin + Jetpack Compose. No Electron, no React Native, no embedded browser. Fast, light, native gestures, dark mode, accent-color customization.
02 Stand-out tools inside
Most of the 95 are 1-tap utilities. These five are deeper — each replaces a paid app or subscription on its own.
Vault
Encrypted password + document vault. PIN + fingerprint. Files re-encrypted to share, decrypted only on-device. Replaces LastPass €36/yr.
Food & Cosmetic Scanner
Barcode → Yuka-style score, halal/vegan/kosher flags, allergen-match against your Diet & Ethics profile, cruelty-free check. Replaces Yuka €12/yr.
Document Scanner → PDF
Multi-page scan with auto-edge-detect, combine into one PDF, share or save to Vault. Replaces CamScanner / CamCard $5/mo.
Heart Rate Monitor
BPM via camera + flash with live waveform + signal-quality indicator. Semi-reliable, varies per phone — disclosed in-app, not hidden.
Material Lab (4 scanners)
Leather (real vs PU/PVC vs vegan), Textile (microfiber risk), Electronics (repair-score per brand), Wood (CITES/FSC). Local DB, no upload.
Link Inspector
Reveals where shortlinks (bit.ly, t.co, tinyurl) actually go before you click. Phishing-warning if the destination looks shady.
03 Independently verified safe
VirusTotal-clean — 0 malicious / 0 suspicious on 75 antivirus engines
Every PTK release is uploaded to VirusTotal before publication. The current build has zero detections across 75 AV engines. Tap the button to verify the SHA-256 hash yourself — no need to take our word for it.
Verify on VirusTotal →04 Do I need an API key (BYOK)?
No. All 95 PTK tools work without any external API key. Camera, sensors, calculators, the vault, the lab scanners (Open Food Facts public data), the network tools, the dev tools — none of them require Anthropic, OpenAI, Google or any other AI provider. PTK is the toolkit you can hand to a phone with no SIM, in airplane mode, and 90% still works.
What about other Biniru tools?
BYOK ("bring your own key") becomes relevant for our AI-heavy tools like Biniôke (image generation per render). For those, we'll publish a separate BYOK explainer when they ship. For PTK specifically: nothing to configure.
