+# FindPenguins — Feature Research
+
+*Researched June 2026. Source: findpenguins.com, App Store, support docs, reviews.*
+
+---
+
+## Overview
+
+FindPenguins is a German travel tracking and community app. Core features are free; premium subscription ($4.99/month or $32.99/year) unlocks more photos per post and ebook exports. Revenue comes from subscriptions and printed photo books ($40–240). It leans more social than Polarsteps — discovery, community, and inspiring other travelers are central to its identity.
+
+---
+
+## Core User Flow
+
+1. User creates a **Trip** (title, dates, cover)
+2. App runs in background with **automatic GPS + flight detection tracking**
+3. User creates **Footprints** — individual journal entries tied to a location and time
+4. Each Footprint can contain: location, title, date, text story, photos, video, weather
+5. Footprints appear in a **chronological timeline** per trip
+6. Trip is shareable; social followers can view, comment, react
+7. At the end, optionally order a printed **photo book**
+
+---
+

+- Route visualized as path on map, not just pins
+
+---
+
+## Footprints (Journal Entries)
+
+Each "Footprint" is the core content unit:
+
+- **Location**: GPS-detected, shown as city/country; uses reverse geocoding (LocationIQ)
+- **Title**: required, user-set
+- **Date**: required, defaults to current time
+- **Text story**: freeform journal text
+- **Photos**: 6 (free) / 10 (premium) per footprint
+- **Videos**: 1 (free) / 2 (premium) per footprint
+- **Weather**: auto-populated at location + time; manually editable
+- **Place name**: auto-detected city/neighborhood/country, editable
+- **Selective sharing**: each footprint can be public, friends-only, or private
+- **Delayed posting**: option to share location with a time delay (privacy feature)
+
+---

+- Up to 6 photos per footprint (free), 10 (premium)
+- 1 video per footprint (free), 2 (premium)

+- High-res stored for photobook printing
+- Cover photo selectable per trip
+
+---
+
+## Statistics

+- Total distance traveled
+- Number of footprints / trips

+- **Travel inspiration**: browse community trips to plan your own
+- **Explore by destination**: search real traveler experiences for any city/country
+
+---
+

+- 5% discount on books with premium
+
+---
+
+## 3D Flyover Video
+
+- Free feature: auto-generates a cinematic 3D video of your route

+- No native app required for viewing (shareable link)
+
+---
+
+## Offline Capability
+
+- Tracker works fully offline (GPS, flight detection)
+- Footprints can be created and edited offline
+- Syncs when connected
+
+---
+
+## What Makes FindPenguins Distinctive
+
+1. **Flight detection**: auto-detects flights and logs them on the route
+2. **3D flyover video**: compelling visual output, free
+3. **Delayed sharing**: useful for solo travelers worried about broadcasting real-time location
+4. **Richer social layer**: comments on individual footprints, community discovery
+5. **Destination exploration**: browse real traveler posts for any place (like a user-generated travel guide)
+6. **Premium photo books**: more polished physical product with friend comments included
+
+---
+
+## Limitations (relevant to our context)
+
+- Requires native app for GPS/flight tracking — not reproducible in a web CMS
+- Social discovery features irrelevant for a solo personal blog
+- Group trip feature has a bug (co-travelers can delete your content)
+- Premium paywall for basic things like more than 6 photos per post
+- Community/social focus means the UX is designed around a social graph we don't have
+- 3D flyover video requires proprietary rendering pipeline
+- Real-time delayed sharing is a privacy feature for apps broadcasting live location — moot for a blog that posts after the fact
