Support
DirectDOPE is in development. There is no app to troubleshoot yet, but there is a real person at the other end of this address.
Questions about the solver, the math, the pricing, or the waitlist: [email protected]

Frequently asked
Can I see the derivation behind the Remington comparison?
Yes. Ask at [email protected] and the full working will be sent to you, including the bisection that established the atmosphere and the reconstruction of time of flight from the published velocity column. The application is closed source. Its mathematics is not.
How do I get off the waitlist?
Email [email protected] and ask. The entry is deleted within 7 days. No account, no unsubscribe funnel, no confirmation loop.
When does it ship?
There is no date. Announcing one before an app exists would be a guess dressed up as a commitment. The waitlist exists precisely so nobody has to keep checking.
Is there a beta?
Not currently. If a closed test happens, it will be announced to the waitlist, and this page will say so at that point rather than implying it now.
Will there be an iOS version?
Android first. The solver core is pure Dart and carries no platform assumptions, so iOS is not blocked later, but there is no iOS date.
I found something wrong in the published numbers on your home page.
Then please send it. That is the single most useful email this project can receive, and it will be answered with the working rather than with a defence.
