LUMIX Tether vs LUMIX Sync vs Image App: Which Panasonic Software?
Panasonic has shipped three pieces of LUMIX software in the last decade and people still confuse them constantly. The short version: LUMIX Tether is the desktop tethering app, LUMIX Sync is the current mobile companion, and Panasonic Image App is the deprecated mobile app that LUMIX Sync replaced. If you're searching for "Panasonic Image App for S5II" — it doesn't exist; you want LUMIX Sync.
One-line summary

Which one do I install?
- Working at a desk with a LUMIX in front of you: LUMIX Tether.
- Out shooting handheld and want a quick wireless remote: LUMIX Sync.
- Updating camera firmware from your phone: LUMIX Sync (Image App can't update newer bodies).
- You have GH5 / older body with Image App installed and it works: leave it alone, but new bodies need Sync.
What changed when Image App became LUMIX Sync
The Image App carried a decade of accumulated UI debt. LUMIX Sync, launched alongside the S5II, rewrites the connection flow around Bluetooth pairing (clock sync, geotag, wake-up) before jumping to Wi-Fi for transfer. It's faster, more reliable, and supports cameras the Image App was never updated for: S5II, S5IIX, S9, GH7, S1RM2, S1M2, G9II. The Image App still exists in the App Store / Play Store for legacy bodies but Panasonic isn't shipping new features to it.
The shared-session trap
One thing all three apps share: only one can hold a camera's control session at a time. If LUMIX Sync is paired in the background on your phone and you sit down at the laptop, LUMIX Tether will refuse to connect until you close Sync. Same for the other direction. Long version: LUMIX Tether vs LUMIX Sync.
