Key Terms
- Academic Term: A period of study such as a semester, quarter, or trimester. Each term can contain multiple courses and has specific start and end dates.
- Course/Class: An individual subject or class taken during a term. Each course has its own assignments, grade calculations, and credit value that contributes to your GPA.
- Grade: A measure of academic performance, typically expressed as a letter (A, B, C, etc.) and percentage. Grades are calculated from assignment scores and can be weighted differently based on course settings.
- GPA (Grade Point Average): A numerical representation of academic performance, typically on a 4.0 scale. GPA is calculated by converting letter grades to grade points and weighing them by course credits.
- Credits: A numerical value assigned to courses indicating their weight in GPA calculations and typically reflecting the hours of instruction per week. More credits mean the course has more impact on your GPA.
Grade Calculations
Default Grade Formula:
- (sum of earned points) / (sum of total points) × 100
- Example: If you earned 85 points out of 100 total points, your grade would be 85%.
Weighted Grade Formula:
- sum((assignment weight × earned points) / (total points))
- Example: For a quiz worth 20% where you earned 18/20 points, it contributes (20 × 18/20) = 18 percentage points to your final grade.
Weighted Grade Options:
- Use Only Graded: Calculates weighted grades using only graded assignments, redistributing weights proportionally.
- Include Ungraded: Treats ungraded assignments as 0 points earned while maintaining their assigned weights.
GPA Calculations
Term GPA:
- (sum of (course grade points × credits)) / (sum of credits)
- Example: An A (4.0) in a 3-credit course and a B (3.0) in a 4-credit course gives: (4.0 × 3 + 3.0 × 4) / (3 + 4) = 3.43 GPA.
Grade Points:
- A/A+ = 4.0, A- = 3.7
- B+ = 3.3, B = 3.0, B- = 2.7
- C+ = 2.3, C = 2.0, C- = 1.7
- D+ = 1.3, D = 1.0, D- = 0.7
- F = 0.0
Can I customize the grade scale?
- Yes, go to Settings
- Select "Grade Scale"
- Adjust minimum percentages for each grade
- Changes apply to all courses
What's the difference between Term GPA and Cumulative GPA?
- Term GPA:
- Only includes courses in the current term
- Shows performance for specific semester/quarter
- Resets each term
- Cumulative GPA:
- Includes all courses across all terms
- Shows overall academic performance
- Updates as new grades are added

Deviant Weather is an iOS app that provides detailed weather information with a unique focus on historical weather patterns and temperature deviations. The app offers comprehensive weather data through Apple Weather and historical data from NOAA.
Basic Usage
How do I add locations to the app?
- Tap the "+" button in the top toolbar
- Enter a city name or address
- Select the desired location from search results
- You can add up to 6 locations total
How do I manage my saved locations?

Understanding Temperature Deviance
What is temperature deviance?
Temperature deviance shows how much the current temperature differs from the historical normal for that location, date, and time. A positive deviance (shown in red) means it's warmer than normal, while a negative deviance (shown in blue) means it's cooler than normal. The intensity of the color indicates how significant the difference is.
How is deviance calculated?
The app compares the current temperature to historical normals from NOAA's climate database. For example, if it's currently 75°F and the historical normal is 70°F, the deviance would be +5°F (warmer). The color intensity changes at specific thresholds:
- Light (0-5°)
- Medium (5-10°)
- Strong (>10°)
Weather Data
Where does the weather data come from?
- Current weather: Apple WeatherKit for real-time updates and local forecasts
- Historical data: NOAA (National Oceanic and Atmospheric Administration)
What time period do the historical normals cover?
The historical normals are based on NOAA's U.S. Climate Normals from 1981-2010. These are 30-year averages including daily temperature normals, monthly averages, and hourly normals for temperature, precipitation, and other weather conditions.
How often is the data updated?
- Current conditions: Every 5 minutes
- Historical normals: Daily updates
- Monthly climate data: Weekly refresh
Features and Display
What do the different chart colors mean?
