Does Protocol support cardio and interval schemas?
Yes. Protocol supports cardio time/distance and HIIT-style patterns as typed, valid targets.

Strong vs Protocol
TL;DR - Strong is a dependable gym logbook. Protocol is a system that runs your routine.
Choose Strong if... Choose Strong if you want a classic tracker with templates, timers, and practical utility tools.
Choose Protocol if... Choose Protocol if you want progression and structure carried by the app, especially as routines become more complex.
The core difference
Strong is mature and reliable for template-first logging workflows, including common tracker utilities many lifters expect.
Protocol is centered on execution semantics: typed routine definitions, schedule logic, and progression behavior integrated into the runtime.
If your challenge is scaling a structured plan consistently, Protocol's engine-led approach is usually easier to sustain.
Head-to-head
| Category | Strong | Protocol |
|---|---|---|
| Templates and routines | High (template-first) | High (runnable definitions) |
| Execution flow | Medium | High (focus-mode flow) |
| Progression baked in | Partial | Engine-led |
| Utility tools | High | High (tools hub) |
| Measurements | High | Medium and expanding |
| Data ownership | Medium | High (local-first + export/restore) |
What Strong is genuinely great at
1.Classic tracker completeness
Strong delivers a familiar and stable feature set for lifters who want templates and logging first.
2.Mature utility workflow
Timer, template, and practical gym utilities are reliable and well understood.
3.Low conceptual overhead
Strong's model is straightforward if you prefer a clean logbook over a system-oriented runtime.
Where Protocol wins
1.Better scaling for structured routines
Protocol keeps routine logic in the system so variable schedules and progression rules are easier to maintain.
2.Schema and intensity correctness
Typed guardrails help prevent invalid target combinations and reduce data drift.
3.Execution-focused architecture
The product is designed around running sessions under fatigue, not only recording what happened.
Brutally honest
- If you want a familiar tracker with minimal learning curve, Strong remains a simple choice.
- If you do not need engine-led progression behavior, Strong can be enough.
Who it's for
Choose Strong if you are...
- Lifters who want a classic logbook + templates workflow
- Users comfortable managing progression logic themselves
- People prioritizing familiar tracking patterns
Choose Protocol if you are...
- Lifters running structured programs that need execution consistency
- Users who want fewer manual transitions from planning to session runtime
- People who value local-first control with system-led progression
Alternative positioning
Searching for a Strong alternative usually signals one of two needs: cleaner execution flow or stronger system constraints. Protocol is aimed at both.
FAQ
Will Protocol force an account before use?
No. The app is local-first, and account linking is optional.
What usually drives switching from Strong?
Most switchers want routines to behave like systems, not only templates they log against.
