"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. Your data stays on your device; the app can auto-lock when sent to background. Eidica is your second visual memory, quiet, organized, and completely yours. Take photos not to forget, but to remember.
