Tredict Newsletter August 2026

Dear , August is a month when, astronomically speaking, not a great deal happens. The solstice is already a few weeks behind us, and the equinox is still a few weeks ahead. At Tredict, though, there's always something going on! ;-) If you haven't come across the Tredict merch shop yet, do have a look and order something. The prices only cover the costs, but I'd love to see plenty of Tredict users strutting about in one. https://tredict.myspreadshop.net/all

Tredict as an Android app on the Play Store

Since May, Tredict can be installed straight from the Google Play Store onto your Android device, so it now sits much more neatly on your phone. A big thank-you to everyone who helped with the testing! Please do leave Tredict a review on the Play Store. That would be brilliant! https://play.google.com/store/apps/details?id=com.tredict.app If you're on Apple iOS, you can do something similar by adding Tredict to your home screen. https://www.tredict.com/faq/install-tredict-on-iphone-or-ipad/

Zwift and Hammerhead Karoo integrations - two-way

If you're a road cyclist or triathlete, you'll be glad to hear that Tredict is now officially integrated with both Zwift and Hammerhead. And it works both ways, so the workouts and training plans you've built in Tredict sync straight across to Zwift or your Karoo. Do leave a comment on the release thread in the Zwift forum to help spread the word. https://forums.zwift.com/t/tredict-integration-now-available-july-2026/669567 To import your older sessions, have a look in the Tredict service settings. https://www.tredict.com/blog/zwift_api_integration/ https://www.tredict.com/blog/hammerhead_api_integration/

The official "Tredict ChatGPT Plugin"

With the official "Tredict ChatGPT Plugin" (formerly the App), ChatGPT users can try Tredict on a free ChatGPT account and get a first taste of AI-assisted training planning. For proper analysis and planning with ChatGPT, though, I'd recommend a paid ChatGPT account, which isn't so heavily limited, or using the "Tredict MCP Server" with another AI provider such as Perplexity or Claude. https://chatgpt.com/plugins/plugin_asdk_app_69aef5b699a0819184512d57743fc1cd

Apple Watch and Stryd integration via Watchletic

You can send planned, structured workouts to your Apple Watch through Watchletic and run them straight from your wrist. The recorded session then syncs back to Tredict automatically for analysis. There's good news for Stryd users too. Watchletic offers a thorough Stryd integration, and that data syncs directly with Tredict as well. https://www.tredict.com/blog/apple-watch-tredict-watchletic-integration/

Apple Watch HRV, sleep and resting heart rate via Shortcuts

Tredict user Maximillian has built Apple Watch Shortcuts to send HRV, sleep and resting heart rate to Tredict through the Tredict Personal API, and he's sharing them with you. Simply superb! https://www.tredict.com/blog/apple_watch_hrv_sleep_resting_heart_rate_shortcuts/

Import five years of Withings history

In the Tredict service settings you'll now find an option to import the last five years of your Withings history. The import covers HRV, sleep and resting heart rate. https://www.tredict.com/changelog/#2026-07-17T09:00:31.000Z
