Guardiax is your personal internet safety assistant. In seconds, it tells you whether an email address, domain, or link is safe to trust — without storing a single byte of your data. Whether you received a suspicious message, want to verify who you're dealing with online, or just want to know if a website is legitimate, Guardiax gives you a clear, actionable answer. IDENTITY CHECK Run a four-dimension risk analysis on any email address. Guardiax checks breach exposure across known data leak databases, spoofing vulnerability through SPF, DMARC and DKIM authentication records, domain trust signals, and online identity presence — then scores each dimension from Low to Critical so you know exactly where the risk lies. IS THIS A SCAM? Paste any URL, domain, or email and get an instant scam risk verdict. Guardiax analyses domain provenance and age, WHOIS ownership records, DNS authentication (SPF, DMARC, MX), public reputation signals, and blacklist status — then explains in plain English what it found and what you should do. THREE VIEWS, ONE APP Not everyone needs the same level of detail. Switch between Simple (plain-English verdict for non-technical users), Standard (prioritised action steps), and Advanced (full technical breakdown) — right from the home screen. PRIVACY BY DESIGN Guardiax only analyses publicly available information. Nothing you scan is stored, tracked, or shared. Ever.

Read full description

Prime Speed Controller is a Safari extension that adds A-B loop repeat, playback speed control, seek, and time-saved tracking exclusively to Prime Video on iPhone and iPad. Perfect for language learners and anyone who wants to get more out of Prime Video. ā–  A-B Loop Repeat Tap A to mark a start point, tap B to mark an end point — the video loops that segment continuously. Replay any dialogue, scene, or lecture as many times as you need. ā–  Playback Speed 15 presets from 0.5x to 5x, with 0.05x fine-tuning. Subtle steps like 1.1x and 1.2x let you boost speed while keeping audio clear. ā–  Forward & Rewind Choose 5, 10, 15, or 30-second intervals. Jump back instantly to catch missed dialogue. ā–  Time-Saved Tracker The panel shows how much real time you have saved by watching above 1.0x speed, accumulated across sessions. Key Features • A-B Loop: mark any segment for continuous repeat • 15 playback speed presets from 0.5x to 5x • Fine-tune in 0.05x steps • Forward and rewind at 5, 10, 15, or 30 seconds • Time-saved tracker displayed in the panel • Settings saved automatically across sessions • Works on iPhone and iPad • Activates only on Prime Video — no other sites • No data sent to external servers How to Use 1.

Playback speed or seeking may be restricted by Prime Video for certain titles. This app does not detect or skip advertisements. This is an independent, unofficial Safari extension.
