A workout log only helps if it's faster than the notes app you're trying to replace. Phyziq is built around that idea: tap to log a set in seconds, let a rest timer count you down, and let the app do the bookkeeping, personal records, history, muscle-group balance, so you can keep your head in the lift. Here's what it does, who it's for, and how to get your first workout logged.
What is Phyziq?
Phyziq is a free gym workout tracker for iPhone that logs your sets, reps, and weight in real time as you train. It covers weighted, bodyweight, and timed exercises, includes a customizable rest timer and RPE tracking, and keeps a complete workout history with personal records, progress photos, and body measurements. Two AI features round it out: snap a photo of any plan to import it, or generate a personalized multi-week program.
The app is made by Foggo Apps, the independent studio of iOS developer Charles Chiejina, and it's well-rated on the App Store with a 5-star rating. Phyziq adapts from your first session to advanced training without forcing a rigid structure on you.

Who is Phyziq for?
Phyziq suits anyone who trains with resistance and wants a record of what they actually did. A few examples:
- Lifters and bodybuilders who log sets, reps, and weight every session and care about progressive overload.
- People following a written program, whether it came from a coach, a screenshot, or a PDF, who want it inside an app without manual retyping.
- Beginners who want a starting program generated for their goals, experience, and equipment rather than guessing.
- Anyone tracking physical change through progress photos, body measurements, and personal records over months.
- Hevy users who want to bring their existing training history along.
How to log your first workout
You can be tracking in about a minute:
- Open Phyziq and start a workout from a pre-made program, a routine you've built, or a single exercise from the 340+ exercise library.
- Log each set as you go: enter weight and reps, or use bodyweight and timed options for exercises that need them.
- Tag set types, warm-up, normal, drop-set, or failure, and add an RPE value to record how hard each set felt.
- Hit the rest timer between sets; set your own duration so it nudges you back at the right moment.
- Finish the workout and review the log. Phyziq automatically flags any new personal records for weight, reps, or volume.
What makes Phyziq different
The AI does the data entry
Two AI features remove the most tedious part of using a gym app. AI Routine Import lets you snap a photo of any workout plan, a coach's printout, a screenshot, a whiteboard, and Phyziq extracts the exercises automatically. AI Program Generation goes the other way, building a personalized multi-week program from your goals, experience level, available equipment, and the areas you want to focus on.
Progress you can actually see
Phyziq turns your logs into a picture of how training is going. It tracks progress photos on a timeline and a full set of body measurements, weight, body fat, chest, waist, hips, thighs, arms, shoulders, neck, and calves. Muscle-group heatmaps show a visual body map of where your work is landing, and exercise history charts let you zoom from a 3-month view out to all-time.
It lives in your Apple Health ecosystem
During a session Phyziq can read real-time heart rate from your Apple Watch, AirPods, or Beats and calculate live calorie burn. It tracks steps toward a daily goal with a home screen widget and walking reminders, imports body measurements from HealthKit, and can export your finished workouts back to Apple Health so everything stays in sync.
A quick note on tracking your training
The single biggest driver of progress in the gym is progressive overload, gradually doing more over time, and you can't apply it to numbers you didn't write down. Logging every set also surfaces patterns a memory won't: a lagging muscle group, a lift that's stalled, a week you skipped. Phyziq's job is to make that record cheap enough to keep that you actually keep it. If timed work and intervals are part of your routine too, our companion guide to building interval workouts in Tempo pairs well with a strength log.
