An example of how a workout and its notes can fit together. These loads and explanations are illustrations, not a generated result or a training prescription.

Under the bar, the app disappears.

The private iPhone build brings sets, load, effort, and rest into the workout screen. Weak-signal and offline behavior are still under test.

Coach threadExample conversation

A coach you can actually talk to.

Coach chat is part of the invited iPhone beta. This illustrative exchange shows the kind of training context a conversation can cover; it is not a recorded response.

YouThe leg curl machine was busy, so I skipped it.

CoachKeep that in your session notes. Which exercises did you finish, and how much time did you have?

YouAnd I only have 40 minutes on Thursday.

CoachLet's review Thursday's planned exercises and decide what fits. A shorter session does not mean we should silently rewrite the rest of your week.

AdaptationIllustrative planning review

Review what happened.
Consider what comes next.

These example edits show a planning discussion, not an automatic output from the app. Training decisions need the wider program and the lifter's context.

The systemKeep the context

Record. Review. Ask.

Useful training records help you ask better questions. These principles are not promises of automatic changes or better training outcomes.

R–01

Keep the record

Record completed reps, load, effort, and relevant notes. Keep the result separate from the target you intended to hit.

R–02

Stalls are data

A missed target is context to review, not an automatic instruction to add work or change the whole program. Look at the pattern and your program's guidance.

R–03

Know the limits

Coach chat does not diagnose pain or clear you to return to an exercise. Seek qualified professional advice for symptoms or an injury.

Straight answersFAQ

Asked constantly.

Is Handler available?
Handler is running an invited TestFlight beta on iPhone. The public App Store listing is not live yet, but you can request beta access through the support page.
What is Handler?
Handler is an AI personal trainer and workout tracker for strength training. It builds your program, lets you log every set, adjusts your next workout, and gives you a coach-style chat thread for questions, debriefs, and check-ins.
How is Handler different from Hevy or Strong?
Hevy and Strong are excellent workout loggers if you already know what to do. Handler is built for people who want the app to write the program, explain the plan, and progress workouts from their logged performance.
How is Handler different from Fitbod?
Fitbod is strongest as a workout generator. Handler is designed more like a coaching relationship: a plan over time, a persistent coach thread, post-workout debriefs, and changes when your schedule, equipment, soreness, or injuries change.
Do I need to know how to program my own workouts?
No. Handler builds your program from a short setup chat about your goals, experience, schedule, and equipment. You can still edit any session, swap exercises, or tell the coach to change the plan.
Does Handler support Apple Watch and offline logging?
Not as public features today. Handler is in an invited iOS TestFlight beta, its Apple Watch companion is in development, and weak-signal logging behavior is still under test.
Is Handler free?
Invited TestFlight access is currently free and does not create a subscription. Public V1 is planned as a paid subscription; exact localized prices and any introductory offer will be shown by Apple before purchase.
Is Handler good for beginners?
Handler is designed to help beginners who want a structured plan, plain-language session guidance, and progression support instead of programming alone. It is still in an invited iOS TestFlight beta, so this describes the intended fit rather than a guaranteed outcome.
Can an AI app replace a personal trainer?
Handler can help with programming, progression, logging, and day-to-day training questions. It cannot observe technique or replace the judgment of a qualified in-person coach or clinician.
Does Handler work for home and garage gyms?
Yes. You set your available equipment during setup, and the coach programs around it, whether that is a full rack, adjustable dumbbells, or bands. Offline logging means a weak garage signal never interrupts a session.
What equipment and goals does Handler support?
It supports strength, muscle gain, and general fitness goals across barbell, dumbbell, machine, and bodyweight setups. You can train at a commercial gym, a home gym, or while traveling, and the plan adapts to what you have.
