Setline for iPhone

Run the workout you already wrote.

Keep strength, cardio, and mobility sessions in authored order. Setline puts the current set and rest clock in front of you, then records every explicit change.

Today

Start in authored order.

The local date resolves to the planned session, including explicit unplanned days. Start without reopening a PDF, note, or spreadsheet.

Player

Keep target and actuals separate.

Complete the planned set, record ordered drop segments, or explicitly skip, add, or defer work. Setline preserves the deviation without rewriting the programme.

Rest

Measure the gap, not just the countdown.

Authored rest, any timer adjustment, and the actual completion-to-next-start gap remain separate. The next target is ready when you are.

Device first

The workout never waits on a network.

The active session reads and writes locally. Private iCloud continuity is implemented but still awaits two-device hardware verification. A connected Significant Hobbies account shares completed-workout summaries with Hub only after local writes; it never receives an active set, targets, templates, or plans.

Setline may fit if

you follow a structured strength, cardio, or mobility programme and want less decision-making between sets.

It is not a coach

It does not prescribe a programme, diagnose readiness, count calories, or turn training into a social feed.

Questions, answered.

Do I need an account?
No. Planning, starting, recording, resting, history, and export all work from local storage. No request sits between you and the next set.
Will it write my programme?
No. Setline ships with one authored twelve-week programme and lets you build bounded custom plans, but it does not generate or prescribe training.
What can leave the iPhone?
If you choose iCloud, Setline can reconcile plans, templates, targets, and completed workouts across your Apple devices. If you connect a Significant Hobbies account, Hub receives completed-workout summaries only. An active workout stays local.
Can I download it or pay for it?
Not publicly. Setline is in internal TestFlight with no public invitation, App Store listing, paid plan, subscription, or checkout. No permanent free or paid model has been announced.
Is it medical or coaching software?
No. It records the programme and measurements you provide. It does not diagnose, prescribe, or decide whether an exercise is safe for you.

Write it once.
Run it set by set.
