Frequently asked questions
What does ADDR do?
ADDR adds two numbers together. It then treats that addition with the full gravity of an enterprise platform: an eight-stage pipeline, a confidence score, a risk level, and AI commentary from NumberGPT. The sum is real; the ceremony is for fun.
Is ADDR free?
Yes. The full addition pipeline, NumberGPT commentary, the Daily Addition, streaks, achievements, and community access are all free. ADDR Pro is an optional one-time $3.99 purchase (not a subscription) that unlocks cosmetic perks. It does not make addition more accurate — addition is already free and correct.
What does ADDR Pro include? Is it a subscription?
ADDR Pro is a one-time $3.99 in-app purchase — there is no subscription and nothing renews. It unlocks a gold PRO badge, premium accent themes, reflective gold confetti, Pro-only stats, and alternate app icons. Bought a new phone? Tap Restore Purchase on the Pro screen to get it back at no charge.
What is the Daily Addition?
Each day, everyone in the world gets the same two numbers. Solve it to keep a daily streak alive and see where you land on that day's leaderboard.
Can I use ADDR with Siri or see it in the Dynamic Island?
Both. Say "add two numbers with ADDR" and Siri runs the addition and reads back the result; recent sums appear in Spotlight search. During processing, the eight-stage pipeline also plays live in the Dynamic Island and on your Lock Screen.
Why does adding two numbers take eight stages?
It doesn't need to. The eight-stage pipeline is a deliberate, theatrical celebration of a very simple operation. You can cancel it at any time using the Cancel button during processing.
Can ADDR subtract, multiply, or divide?
No. ADDR only ever adds. Other operations are not on the menu and never will be, regardless of what any roadmap implies.
What are easter eggs?
Certain additions trigger special hidden responses from NumberGPT — famous numbers, palindromes, and a few disputed results. Rare easter eggs receive a gold badge. Keep adding to discover them.
Does ADDR collect my data?
No. Your additions, streaks, and achievements are stored locally on your device and are not sent to our servers. See our Privacy Policy for full details.
How do I keep my streak alive?
Complete at least one addition each day. If you miss a day, your current streak resets, but your longest streak is always remembered.
