If you lift weights, you have probably tried a strength logger. Hevy and Strong are two of the most popular options. Both do the same core job: track your sets, reps, and weights, then show you the trend over time. They are clean, fast, and good at what they do. ooddle is in a different category. It logs lifts too, but the lift log is one piece of a five-pillar system that includes Metabolic, Movement, Mind, Recovery, and Optimize. The decision is not really Hevy vs Strong vs ooddle. It is whether you want a tracker or a system.
Quick Comparison
- Hevy: clean strength logger with social features. Free tier is generous. Strong on community and routines.
- Strong: original strength logger. Minimal interface. Trusted by serious lifters who just want to log and look at numbers.
- ooddle: full health system. Lifting, sleep, stress, nutrition, and recovery in one plan. Built for people who want lifting to fit a life, not the other way around.
Hevy: Strength of the Tool
Hevy is well designed. The interface is fast. Logging a set takes one tap. The history view is clean. Routines are easy to build and share. The social feed lets you follow other lifters, which some users find motivating. Hevy Pro adds advanced analytics, body measurements, and unlimited routines.
If you already know your training plan and you just want a tracker that does not get in your way, Hevy is excellent. The team ships updates regularly. The app is responsive. The data export options are reasonable.
Where Hevy falls short is everything outside the lift. There is no nutrition planning, no sleep tracking, no stress management, no recovery protocol. If your lifting is going well but your sleep is wrecked, Hevy will not tell you. It is a logger, not a coach.
Strong: Strength of the Tool
Strong is the older app of the two. It has been the default for many serious lifters for years. The interface is intentionally minimal. Log set, log set, log set, done. The history graphs are simple and useful. The free version covers the basics. Strong Pro unlocks unlimited workouts, advanced charts, and Apple Watch integration.
Strong's strength is its restraint. It does one thing. The app does not try to coach you, motivate you, or sell you supplements. For lifters who already know what they are doing, that minimalism is the appeal.
The same restraint is the limit. Strong does not connect to nutrition, sleep, or stress data. It does not adapt your training based on your recovery. It is a clean log, nothing more, nothing less.
ooddle: Strength of the System
ooddle treats lifting as one pillar in a five-pillar plan. The Movement pillar tracks your lifts, but the plan also looks at sleep quality, stress load, nutrition, and recovery. When sleep drops, the plan suggests pulling back on volume. When stress spikes, it shifts the workout to a lower-intensity option. When recovery is solid, it pushes harder.
This is what coaches do. ooddle automates a version of it. You log your lift, and the system uses that data alongside everything else to update your plan for the week. Our protocols are personalized plans built from the five pillars: Metabolic, Movement, Mind, Recovery, and Optimize.
For lifters who only want to track sets and reps, this is overkill. ooddle is heavier than Hevy or Strong. The trade-off is that the heaviness is the point. You are not paying for a logger. You are paying for an integrated system.
Key Differences
Hevy and Strong are tools. They wait for you to bring a plan, then they record it. ooddle is a system. It builds the plan, watches the inputs, and adjusts as you go.
Hevy and Strong are cheap or free. ooddle has a free tier (Explorer), then Core at $29 a month and Pass at $79 a month. The pricing reflects the scope. A logger should be cheap. A system that includes coaching, plan adjustment, and full health tracking is priced like a small gym membership.
Hevy and Strong are isolated apps. ooddle pulls in sleep data, food intake, stress patterns, and movement, then synthesizes. Same with goals: a logger lets you set a PR target. A system understands that your PR target depends on your sleep, your stress, and your recovery, and it plans accordingly.
Who Should Choose What
Choose Hevy if you have a coach or a plan you trust, you just want a clean log, and you like the social feed. It is a great tool for people who already know what they are doing and want a tracker that does not get in the way.
Choose Strong if you want the same as above but with even less noise. Strong is for the lifter who has been training for years, knows their program, and just wants to log fast and read graphs.
Choose ooddle if you want lifting to fit a real life. If your sleep is inconsistent, your stress is high, or you are juggling work and family alongside training, you will get more from a system that connects the dots than from a logger that records numbers in isolation. Plans like Core ($29 a month) and Pass ($79 a month) include the full five-pillar system, with Pass adding one-on-one check-ins for people who want a real human reviewing the plan.
None of these apps is wrong. They serve different jobs. If you want a clean strength logger, Hevy and Strong are both excellent. If you want a system that treats lifting as one part of your health and adjusts everything together, ooddle is built for that. Pick the tool that matches the job. The wrong choice is not the wrong app. It is using a logger when you needed a system, or a system when you only needed a logger.
What Most Lifters Get Wrong About Tracking
Most lifters track religiously for 6 to 8 weeks, then drop the log. The reason is usually not laziness. It is that the log is a chore without a payoff. They write down sets and reps, then never look at the data again. The log becomes a ritual without a feedback loop.
The fix is to build a 5-minute weekly review into the practice. Open the app. Look at the trend graphs. Note one thing that improved and one thing that stalled. Adjust next week's plan based on the observation. This small loop turns a passive log into an active feedback system, and it is the difference between a tracker that gets used and a tracker that gets abandoned.
Combining Tools in Practice
Many serious lifters end up using both a focused logger and a system. They log lifts in Hevy or Strong because the interface is fast and they like the data. They run their broader plan in ooddle because the lift log is just one piece of a real life. The two do not conflict. The logger captures the workout. The system handles everything else.
If you go this route, do not double-log. Pick one place to enter sets and reps. Most lifters prefer the dedicated logger for that part. Use ooddle for sleep, stress, recovery, and weekly planning. The combination works because each tool sticks to its strength.
