A photo keeps the scene. Five seconds of sound brings back the air around it. Save both together as a private sound postcard.
A photo can keep the view. Sound can bring back the air around it.
Sound Postcard pairs one photo with exactly five seconds of ambient sound, creating a small private memory you can return to.
• PHOTO + FIVE SECONDS OF SOUND
Take a photo or choose one from your library, then keep a five-second recording with it.
• REAL WAVEFORMS AND PLAYBACK
Each waveform is generated from its recording. Play and pause the sound directly from cards and detail views.
• MAP AND MONTHLY ALBUM
Optionally attach a place to revisit memories on the map, or browse them by month in the album.
• SHARE A POSTCARD
Export a postcard-style image or a five-second video with sound. Preview your layout before sharing.
• PRIVATE BY DESIGN
No account is required. Photos, audio, locations, and notes stay on your device. There are no ads, analytics SDKs, or developer-operated servers.
• MANUAL BACKUP (PRO)
Export all postcards from Settings and restore them later. Back up before deleting or reinstalling the App because deleting it removes local data.
The free version lets you create up to five postcards, and existing postcards always remain available. Sound Postcard Pro is a one-time purchase that enables unlimited saving plus backup and restore. It is not a subscription.
