"Why did I take this photo?" We all take photos to remember something: a parking spot, a product we liked, an important document, or just a moment we don’t want to forget. But if you don’t write a note right away, that photo will mean nothing days later. That’s why Eidica exists. The moment you take a photo or video, a note card appears. Write down why you captured it. Your media isn’t saved to iPhone Photos; it stays safely inside Eidica. This keeps your Photo Gallery for memories only, while everything else stays organized in Eidica. Try all features free for 7 days. No automatic charging. Your trial will not turn into a paid subscription unless you manually choose a plan. MAIN FEATURES Add notes instantly while taking photos or videos. Organize your notes into custom folders. Lock the app or folders with Face ID. View notes on a map with Apple Maps integration. Set reminders for important notes. Securely back up with iCloud and restore on new devices. Add up to 5 media files per note (1 video, up to 30 seconds). Search by location to find notes easily. Quickly add notes to screenshots to save ideas, messages, or reminders. Add notes to existing photos and videos from your gallery directly into Eidica. Maximum privacy: No account, no email.

Engichat is the AI copilot for practicing civil, structural, electrical, and mechanical engineers — calculations, code checks, CAD, and field inspection in one app you can use from the office or the job site. Unlike a general chatbot, Engichat shows its work and cites the clause. Every calculation runs on validated engineering formulas — not guessed arithmetic — and every code answer is grounded in the actual standard, so you get results you can defend and stamp. DESIGN & VERIFY AGAINST U.S. CODES • Structural: beam flexure, shear, deflection, columns & foundations — ACI 318-19 and AISC 360-16, with the section and clause shown • Wind & seismic loads — ASCE 7-16 (MWFRS, equivalent lateral force) • Electrical: conductor sizing, breaker selection, voltage drop & load calcs — NEC 2023 (incl. Article 220 & 430) • Mechanical & piping — ASME B31.3, ASHRAE Fundamentals • Full working shown, every step, with the code reference beside the result ASK ANY CODE IN PLAIN ENGLISH Get answers with specific clause citations — not a confident guess. When a source is available, Engichat tells you exactly where the answer came from. SPECIALIST AI, NOT ONE GENERIC BOT Your question is routed to the right expert agent — structural, electrical, mechanical, chemical, petroleum, or CAD — for domain-accurate answers. CAD AUTOMATION Generate AutoLISP scripts and drawings from a description. Turn hours of drafting into seconds and open the result straight in AutoCAD. ENGINEERING VISION Point your camera at a site condition, drawing, or component. Analyze, inspect, and measure in the field — no desktop required. WORK, NOT JUST CHAT Email reports, update Sheets, schedule meetings, and manage tasks in Jira — straight from the conversation. Engichat takes the action, not just the note. BUILT FOR TEAMS Shared workspaces, a reusable formula-template library, and multilingual support (English, French, Spanish, Thai). TRY IT FREE Start free every week, upgrade when you need more. Starter, Pro, and Premium plans available. Engichat assists your engineering judgment — it does not replace the review, verification, and professional responsibility of a licensed engineer. Always confirm results against the governing code and your own analysis. From Securestack Technologies — the team that builds trustworthy, secure AI. Terms of use: https://www.engichat.com/terms
