EchoSeed

**Application Name:** EchoSeed
Brief summary: Plant the echoes of this moment, dedicating them to the future self.
**Core Concept:**
EchoSeed is a unique digital time capsule application. It is not merely a means of recording; it is also a ritual about "waiting" and "surprise". You can store words, photos, or a precious audio recording (echo) within the capsule and set strict conditions for unlocking. Before the unlocking moment arrives, these memories will be like seeds buried in the soil, quietly waiting for the moment of breaking through the soil.
**Main Functions:**
- **Memory Burial**: Easily create a time capsule, supporting long texts, high-definition photos, and highly immersive voice "echoes".
- **Fun Unlock Conditions**:
- **Time Pact**: Set a specific future time point (such as your birthday one year later) to unlock.
- **Battery Adventure**: Set a specific percentage of battery (such as 5%) below which the memory can be unlocked. Encounter your past in an unexpected low-battery moment.
- **Sound Easter Eggs**: Support recording and sealing of ambient sounds or inner thoughts. When unlocked, it provides a dynamic waveform feedback to relive the emotions at that time.
- **Privacy Protection**: Built-in FaceID/Fingerprint encryption ensures that your private memories can only be unlocked by you.
- **Discovery Journey**: Manage all unlocked memory fragments in the "Discovery" library. Supports smooth audio playback and progress control.
**Usage Scenarios:**
- Write a letter to yourself one year from now, documenting your current dreams.
- Record the lively sounds of the current environment and save it for the lonely moments in the future.
- Seal a photo of your crush and set it to be opened on a late night in a distant future.
- Use it as an emotional trash can, burying your unhappiness in capsules and examining it after time has diluted everything.
