DetectQR
Read full descriptionHide full description
QR codes often contain multiple redirects that can lead to dangerous websites โ a security risk that has never been addressed so effectively before. Whether in everyday life, while shopping, or on the go, DetectQR gives you the confidence to scan any QR code without worry. Unlike conventional QR code scanners that only display the visible link, DetectQR analyzes the complete redirect chain and resolves every QR code to its final destination link, allowing you to see exactly where it leads before opening it. Every scan is processed in a secure cloud environment, keeping your device safe. DetectQR goes beyond resolving redirect chains. An integrated security check detects potentially dangerous websites and protects you from phishing, malware, and other online threats that might be hidden behind seemingly harmless QR codes. You can also check manually entered links to detect potential threats before visiting the website. Additionally, the Pro version features AI-powered security analysis, real-time traffic insights (including a domain-age check and visitor data from the previous month), as well as a screenshot preview of the website. The intuitive user interface makes the app incredibly easy to use. Scan, detect, and browse safely โ with DetectQR.

Chronograde

Know your watches beyond a single reading. Chronograde brings together microphone-based estimates, manual drift records and your collection history. FREE TO START Keep an unlimited watch collection with photos and details. Use the Timegrapher for acoustic rate and beat-error estimates, save up to 10 manual readings, and complete one guided Regulation Coach run. iCloud sync and JSON backup remain free. UNDERSTAND THE READINGS Acoustic results depend on the watch, microphone placement and background noise. Manual readings compare displayed watch time with a network reference or the labeled device-clock fallback; timing and reference errors affect the result. Estimates do not replace professional testing. COMPARE SESSIONS (Chronograde Pro) Compare two manual sessions by observed daily rate, reading count, elapsed coverage and recorded positions. Preview and share a comparison PDF. A difference does not prove a service effect. WEAR & SERVICE (Chronograde Pro) See distinct logged days per watch over 30, 90 or 365 days. Days without entries mean not logged. Keep wear and service records with provider, cost and notes. PRIVATE REPORTS (Chronograde Pro) Choose watches, history and a date range, then preview and share a PDF. Serial numbers, notes, amounts and photos are excluded by default. A report is not a backup, appraisal or certification. MORE HISTORY (Chronograde Pro) Record unlimited manual readings and sessions, explore rates by position and repeat guided Regulation Coach runs. REFERENCE & EXPORT (Chronograde Pro) Use a large reference clock with available network time correction. Import watches from CSV and export records to CSV or Excel. MEMBERSHIP Choose monthly, annual or one-time Lifetime access. The free tier may display advertising with your consent; active Pro access removes ads. Optional paid themes are separate purchases. --- Subscription details: Chronograde Pro offers monthly or annual subscriptions. Eligible customers can start with a 14-day free trial.
