Last Updated: September 27, 2026

🚀 Getting Started

DD Dive Calculator works out a dive’s total score from its degree of difficulty (DD) and the judges’ awards, the same way it’s calculated at a meet.

Enter the DD for the dive (for example 2.4). The DD box is selected when the app opens, with a blinking cursor. The first time you open the app, a “Start here” tip points to it
Enter each judge’s score: 2, 3, 5, or 7 judges (or 9 with the NCAA 9 switch on)
Read the total: it updates as you type
Tap AC to clear everything for the next dive

🏊 How Scoring Works

Judges	Calculation
2	Both scores × DD. The diver’s final meet total is then multiplied by 1.5
3	All three scores × DD
5	Drop the highest and lowest, then the middle three × DD
7	Drop the two highest and two lowest, then the middle three × DD
9 (NCAA only)	Drop the two highest and two lowest, then the middle five × 0.6 × DD

Two-judge meets: the ×1.5 is applied once, to the diver’s final total for the event, not to each dive. The app shows each dive’s score as it appears on the scoresheet (for example, DD 2.3 with scores 6.5 and 6 is 12.5 × 2.3 = 28.75) and notes “×1.5 in the final total (2-judge meet)” underneath.

Nine judges: turn on the NCAA 9 switch above the judges’ scores to add boxes for judges 8 and 9. The setting is remembered until you turn it off. The 0.6 (three-fifths) factor keeps a nine-judge score on the same scale as a three-judge score.

Example (5 judges, DD 2.4): scores 6.5, 7, 7, 7.5, 8. Drop 6.5 and 8, so 7 + 7 + 7.5 = 21.5, and 21.5 × 2.4 = 51.60.

Totals are shown to two decimal places. Dropped scores are shown struck through, so you can see which ones counted.

📱 Using the App

Entering Numbers

DD accepts values from 1.0 to 4.9 with one decimal place
Scores accept 0 to 10 in half points (for example 6, 6.5, 10)
Entries advance automatically once complete (for example 2.4, 7.5, or 10)
.5 adds a half point in one tap (7 then .5 gives 7.5)
Next moves to the following box without finishing the current one
Delete (⌫) removes the last digit. If the box is empty it moves back to the previous box. Hold it to delete quickly
Tap any box to jump straight to it and edit it
The blinking cursor shows which box your next key will go into
If you start typing scores before the DD, the DD box pulses to remind you it’s empty (the total can’t be worked out without it)

The Total

The total appears as soon as you have a DD and a valid number of scores (2, 3, 5, or 7)
If you have entered 1, 4, 6, or 8 scores, the app tells you what’s missing instead of showing a total
The line under the total shows the math used, for example 21.5 × 2.4

❓ Common Questions

Why don’t I see a total? Check that you’ve entered a DD and exactly 2, 3, 5, or 7 scores (or 9 with NCAA 9 on). With 4 or 6 scores there is no standard way to drop high and low scores, so the app waits for you to add or remove one.

Why won’t a number go in? The app only accepts valid entries: DD from 1.0 to 4.9, and scores from 0 to 10 in half points. For example, 7.3 or 11 can’t be entered as a score. You’ll feel a short vibration when an entry is rejected.

Can I type a DD like 0.9 or 5.0? No. Competition DDs fall between 1.0 and 4.9, so the calculator only accepts that range.

Does the app save my dives? No. The app is a quick calculator: dives aren’t saved or uploaded. Tap AC to start the next dive.

Why is my two-judge dive score lower than I expected? Under NCAA rules the 1.5 multiplier for two judges is applied to the final meet total, not to each dive, so each dive score matches the official scoresheet.

Does the app need internet access? No. It works fully offline, on the pool deck or anywhere else.

Does it work in dark mode? Yes. The app follows your device’s light or dark setting.

Why doesn’t the app rotate? The calculator is designed for one-handed use in portrait, so it stays upright when you turn your phone.

Can I use it on an iPad or Android tablet? Yes. On iPad it runs in an iPhone-sized window, and on Android tablets it shows the same phone-sized layout in the center of the screen.

📚 Rules Sources

The calculator follows these published rules:

NCAA Men’s and Women’s Swimming and Diving Rules, Rule 6, Section 6 (Computation of Diving Scores): cancellation of awards for 2, 3, 5, 7 and 9 judges, multiplication by the degree of difficulty, the 0.6 factor for nine judges, and the 1.5 final-total multiplier for two judges. NCAA playing rules · 2021–23 rules book (PDF)
NFHS (high school): all three scores count with three judges; the middle three count with five or seven judges. NFHS: Judging Diving? Oh, No! · NFHS Swimming and Diving Rules
USA Diving / World Aquatics: seven judges, the two highest and two lowest awards cancelled, the remaining three multiplied by the degree of difficulty; awards from 0 to 10 in half points. USA Diving: Judging and Scoring

Rules can change from season to season. If your meet uses a local variation, your meet referee’s scoresheet is the final word.
