interesting digital watches

[tuxfish]

Yes, there should be RPN calculator apps still available for smartwatches.
But I am not sure, If these apps are fun to use or not (@ these small SmartWatches). ;-)

1. **Apple Watch**:
- **RPN Calc** and **PCalc**

2. **Wear OS (formerly Android Wear)**:
- **Wear Calculator** and **Scientific Calculator**

3. **Garmin**:
- **RPN Calculator** (-> Garmin Connect IQ Store, for Garmin smartwatches).

Cheerio !
