For hybrid athletes on iPhone and Apple Watch
Two currents.
One athlete.
Damascus Fit is being built for people who train endurance and serious strength as equal goals: one plan for the swim, the ride, the run and the barbell, that shows its reasoning.

Two plans. One body.
Train for a triathlon and lift seriously, and you're usually juggling two plans that don't know about each other. The long ride and the heavy leg day still land on the same legs.
Damascus Fit is being built to hold both in one plan: endurance and strength as peers, not a main sport with the other bolted on.
What's in the test build.
Damascus Fit is in private testing on iPhone and Apple Watch. Here's what the current test build is designed to do. It will keep changing as testing goes on.
-
It starts with Pre-Game.
Before the app sets a single weight, it needs to see how you train. In Pre-Game you pick your own sessions and log them, and Damascus Fit gathers the observations it needs. The week adjusts as you go.
Until then, it says No recommendation rather than guessing.
Today, in Pre-Game. From the current test build. -
Your lifts, your numbers.
Build a session from a library of hundreds of exercises, swap what doesn't suit you, and mark anything Not for me so it's never offered again. Until the app has an Estimated max for a lift, you choose the weights and reps. It learns that estimate from the sets you log.
-
Phone and wrist, one workout.
Start a workout on iPhone and your Apple Watch runs the same one. Log a set on either, and both stay in step.
-
Right on your Lock Screen.
During a workout, a Live Activity shows your exercise, your set and your rest, and you can log a set without opening the app. Today and Week widgets show what's planned.
-
Bring your history.
Import a Fitbod export on your iPhone. The file is read on the phone, and you can undo an import later.
Fixed rules. Shown work.
Damascus Fit is built to be trusted the boring way: by showing what it did and why.
- Fixed rules decide.
- Training decisions come from fixed rules with set limits, and the app shows the reasoning and sources behind them. No language model writes your plan.
- Ask why.
- Recommendations carry a Why link to the reasoning, and a View evidence link to what that reasoning rests on.
- Estimated means estimated.
- Numbers the app works out, like an estimated max or a rest time, are labeled Estimated, and the app shows how they were worked out.
- It holds back when it doesn't know.
- When there isn't enough data to recommend something, Damascus Fit says so instead of inventing a number.
- Your clinician decides clearance.
- Damascus Fit plans training for adults who are cleared to train. It isn't a medical device and doesn't give medical advice.
Your training stays yours.
There's no Damascus Fit server. Here's where everything lives.

Named for Damascus steel.
Damascus steel is known for being hard and flexible at once: distinct strengths forged into one piece. That's the athlete this app is being built for. Serious endurance and serious strength, as one.
The mark is two currents, copper and navy, running side by side. They align. They never merge.
Questions, answered plainly.
Can I download Damascus Fit?
Not yet. It's in private testing on iPhone and Apple Watch. When it reaches the App Store, this page will say so.
What will it run on?
An iPhone with iOS 26 or later. The Apple Watch app needs watchOS 26 or later.
Does AI write my plan?
No. Fixed rules make the training decisions. When they don't have enough to go on, the app tells you rather than guessing.
Is it medical advice?
No. Damascus Fit is a training-planning app, not a medical device. If you're returning from surgery, illness or injury, your clinician decides when you're cleared to train. The app never does.
