Hi David.

You’ve done an incredible amount of work. I never stop being impressed by what Intervals can do. We are really looking forward to the iOS app.

[sprouty76]

Seems like a perfect time to say thank you to the team for the frankly amazing job you do. It really beggars belief that you offer this for free!

[yokuha]

@david and All on the team, you are doing an amazing job – thank you!
I also enjoyed the podcasts, esp. learning more of the history, a large part of which I participated on the very surface, and you bringing up the AI coaching ideas and discussions and also the pro teams:-)
In any case, we can only be happy and look forward to even better analysis of our sports:-)

Annual plan builder

[Another_Intervaler]

Yay, great job! Also thanks for the constantly flowing communications, which often seems to be sorely missing for other small dev teams.

[AlpineCoach]

Solid work team, excited to see what you come out with in 2026

[JS_MTB]

Thank you all for the hard work. Love this site and glad I found it. It reduced the amount of apps I needed all the while it also enhanced my structured training.

[Clive_King]

David feels like I been here forever and I’m very grateful for your fantastic achievement with intervals.icu. i have no hesitation in recommending this platform.

Thankyou also for the opportunity to enable the development of my ChatGPT AI app also. www.cliveking.net. Long may the journey evolve to help all athletes.

I’m really excited to see this

[tomekk]

Thanks for your work. Looking forward to the android app!

[itachi95]

just by curiousity, do you will use a multi-platform framework for iOS and Android development (Flutter, React Native) or do you will go full native way ?

[david]

Very likely something multi-platform that can use as much of the existing codebase as possible.

[Brian_Frost]

Any chance the iOS app will sync natively with Apple Watch/Apple Health?
