## Version history (last 5 releases)

### 1.0.6 — 2026-08-14

Fixes reporting. If you told us a sauna had closed or left a review and it never seemed to send, it will now.

The Gold list is complete: all 143 curated venues are ranked, including Szechenyi, Pamukkale, Thermae Bath Spa and Therme Vals.

Better categories across Japan, Finland and the US. Municipal bathhouses, hot springs and jjimjilbang are now labelled properly, and sauna suppliers no longer show up as places you can bathe.

### 1.0.5 — 2026-08-10

Every venue now has a real description: what it is, where it is, and what you will find there, written from verified sources rather than guesswork.

Also in this release:
- Opening hours for over 25,000 venues
- Star ratings and review counts on venue cards
- More reliable background data updates
- Hundreds of accuracy fixes: corrected countries, merged duplicates, and closed venues removed

### 1.0.4 — 2026-07-20

Massive data update: the index grows to 74,000+ verified saunas and bathing spots across 200+ countries, with fresh websites, phone numbers and hours for thousands of venues.

### 1.0.3 — 2026-06-15

• Verified thousands of venues and removed ones that have closed
• Corrected map pins for more accurate locations
• Cleaner filters and a smoother map

### 1.0.2 — 2026-06-10

Reliability fix: saunas now load correctly on all devices including iOS 26. If you had an empty map, this update resolves it.
