- 💰 Revenue: Modest — $1K - $7K/mo · INDIE tier · medium confidence, trajectory unclear.
- ⭐ Quality: 4.63★ across 49 reviews — weak — significant quality concerns.
- 📍 Market: Not yet charting in any of the 9 monitored markets.
- 📈 Growth: ⚠ last update 2234d ago — possibly dormant.
- ⚠️ Risk: High — bug mentions above category norm, rating drift -1.91 ★ (recent 50 vs lifetime), dormant (2234d since update).
🎯 For competitors: Vulnerable. Quality drift + slow updates create a clear opening for a fresh competitor with active dev cadence.
💵 For acquirers: Estimated asking range 12-22× monthly = $35K-$65K. Discount applied for operational risk..

★★★★★ Can I get a answer
Why doesn't the app have a option to save the video back into your camera roll? Also why does the app automatically rotate your screen when you look at the video in the app could you fix that and get the feature to have the video save …
★★★★★ Great

The only difference is the theme witch I like this one better…
