DE vs SI Converter
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
DE
This app displays real-time and historical radiation measurements from stations across Germany. It allows users to find nearby stations, view their operational status, and access data up to 365 days in the past. The information is sourced from the ODL monitoring network.
- Interactive radiation map
- View current and past measurements
- Find nearest measurement station
- Check station operational status
- Access 365 days of historical data

DE-Radiation interactively shows you the distributed radiation measurement stations in Germany and their measured radiation values. With the help of this app, you can also search for the nearest measurement station in your vicinity and view the current and past measurement values. In addition, DE-Radiation provides a summary of all the measurement stations located in Germany, their operational status, and average measured values. The data displayed in the app is based entirely on the ODL monitoring network of the Federal Office for Radiation Protection (BFS), with the option to view radiation values up to 365 days in the past. If you allow the app to locate your current position, you can determine the distances to the individual stations and find the nearest station to you. This app is made based on a private project and has no ties to the Federal Office for Radiation Protection (BFS). For questions, change requests, or suggestions, we are of course very grateful at any time: info@app-anthems.com

SI Converter is allows you to easily convert unit following the global standard of measurement is the International System of Units (SI). The intent of this app is to provide a convenient way to convert between the various units of measurement within different systems, as well as to provide a basic understanding of the systems currently in use, and how they interact. Supported Units: Area: Square Megameters (Mm²) Square Kilometers (km²) Square Meters (m²) Square Centimeter (cm²) Square Millimeters (mm²) Square Micrometers (µm²) Square Nanometers (nm²) Square Inches (in²) Square Feet (ft²) Square Yards (yd²) Square Miles (mi²) Acres (acres) Ares (a) Hectares (ha) Lengh: Megameters (Mm) Kilometers (kM) Hectometers (hm) Decameters (dam) Meters (m) Decimeters (dm) Centimeters (cm) Millimeters (mm) Micrometers (µm) Nanometers (nm) Picometers (pm) Inches (in) Feet (ft) Yards (yd) Miles (mi) Scandinavian Miles (smi) Light Years (ly) Nautical Miles (NM) Fathoms (ftm) Furlongs (fur) Astronomical Units (ua) Parsecs (pc) Pressure: Newtons Per Meter Squared (Equivalent to Pascals) (N/m²) Gigapascals (GPa) Megapascals (MPa) Kilopascals (kPa) Hectopascals (hPa) Inches of Mercury (inHg) Bars (bar) Millibars (mbar) Millimeters of Mercury (mmHg) Pounds Per Square Inch (psi) Temperature: Kelvin (K) Degree Celsius (°C) Degree Fahrenheit (°F) volume: Megaliters (ML) Kiloliters (kL) Liters (L) Deciliters (dL) Centiliters (cL) Milliliters (mL) Cubic Kilometers (km³) Cubic Meters (m³) Cubic Decimeters (dm³) Cubic Millimeters (mm³) Cubic Inches (in³) Cubic Feet (ft³) Cubic Yards (yd³) Cubic Miles (mi³) Acre Foeet (af) Bushels (bsh) Teaspoons (tsp) Tablespoons (tbsp) Fluid Ounces (fl oz) Cups (cup) Pints (pt) Quarts (qt) Gallons (gal) Imperial Teaspoons (tsp) Imperial Tablespoons (tbsp) Imperial Fluid Ounces (fl oz) Imperial Pints (pt) Imperial Quarts (qt) Imperial Gallons (gal) Metric Cups (metric cup) Mass: Kilograms (kg) Grams (g) Decigrams (dg) Centigrams (cg) Milligrams (mg) Micrograms (µg) Nanograms (ng) Picograms (pg) Ounces (oz) Pounds (lb) Stones (st) Metric Tons (t) Short Tons (ton) Carats (ct) Ounces Troy (oz t) Slugs (slug) angle: Degrees (°) Arc Minutes Arc Seconds Radians (rad) Gradians (grad) Revolutions (rev) Speed: Meters Per Second (m/s) Kilometers Per Hour (km/h) Miles Per Hour (mph) Knots (kn) time: Hours (hr) Minutes (min) Seconds (sec) Milliseconds (ms) Microseconds (μs) Nanoseconds (ns) Picoseconds (ps)

Verdict
The clearest difference is price: SI Converter at Free against DE's $0.99. DE's advantage is ads (none vs shown). On in-app purchases, device support and iOS requirement there is nothing between them.
