With SEKONIC LD, you can use the full functionality of the spectrometer C-4000. You can remotely control the C-4000 via Bluetooth and view graphs of measurement data in various way. It displays illuminance (lux or foot-candle), deviation (⊿uv), color temperature (K), color rendering index (CRI/TM-30), and CIE1931 chromaticity coordinates (x,y). and imports stored data from the C-4000. SEKONIC LD offers upgrade option with in-app purchases (3-month subscription, 12-month subscription), including a 2-week free trial. With the upgrade, you can import drawings such as lighting layouts or site photos, and link measured values directly on them. Even if you stop the measurement midway, you can add notes to the saved data, making it convenient for multiple measurements. You can also attach smartphone images and notes to each measurement data. Location information of sites can also be attached with GPS data. Compile project data into simple reports, output as PDFs, or export as CSVs for further processing.

realxreal: MFA for People Deepfakes are no longer science fiction; they are the new standard for modern crime. In 2025 alone, over $1 billion was lost to AI-powered impersonation scams. From the Ferrari CEO deepfake scandal to sophisticated "kidnapping" hoaxes targeting families, scammers are now using real-time voice and video cloning to bypass every traditional layer of trust. The internet was built for connectivity, but it never learned how to verify who is actually on the other end of the line. We did. realxreal is the next layer of trust for the digital age; we are multi-factor authentication for human interaction. HOW IT WORKS Every contact in realxreal is assigned a pair of rotating codewords: one for you, one for them. These words are cryptographically synced and change automatically every 60 seconds. When you start a call, video chat, or sensitive conversation, simply glance at your screen and state your codeword. Have your contact do the same. If the words match what is displayed on both your screens, you have mathematically verified that you are speaking to the real person, not an AI clone. WHY CODEWORDS? In an era where voices, faces, and phone numbers can be perfectly imitated in milliseconds, visual and auditory "cues" are no longer proof of identity. Codewords act as an immutable barrier against AI impersonation. Because these words rotate every minute, they provide "perfect forward secrecy" for your conversation. Even if an attacker were to capture audio or video from a previous call, the data would be useless sixty seconds later. realxreal strips away the illusion of the deepfake, leaving only the truth of the person on the other end. GETTING STARTED 1. Define your profile: Give yourself a display name. 2. Import your contacts or add contacts manually: realxreal instantly generates and syncs unique codeword pairs for everyone in your address book. 3. Sync up: Scan a QR code in person or send an invite link to verify a contact. 4. Verify: Just say your codeword and listen for theirs. Both parties need realxreal to verify identity. Start by syncing with your most frequently called family members and colleagues. INTEGRATES INTO YOUR LIFE Don't change your habits. realxreal works alongside whatever you already use: phone calls, video meetings (Zoom, Teams, FaceTime), voice notes, or texts. It is the silent, third-party security layer that fits into your existing routine without forcing you to switch apps or platforms. PRIVACY BY DESIGN realxreal is built on a zero-knowledge, local-only architecture. Your data is yours: Your contacts and cryptographic seeds never leave your device. No central tracking: We don’t maintain a server that knows what your codewords are, who you talk to, or when you talk. No accounts: There is no "realxreal account" to hack, track, or sell. It’s just math, your device, and your trust. Terns of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://www.realxreal.app/privacy.html
