Log your protein. Watch him grow. Every gram you log pumps Jack Steel up — and hitting your daily goal sets off the celebration.
iPhone · $0.99/month, $9.99/year, or $30 once
Jack Steel's Protein Tracker is a gamified protein tracker for iPhone from WristSkill Labs, LLC. You set your own daily protein goal, log grams as you eat, and the mascot — Jack Steel — grows as your day fills. Streaks, XP, and levels reward showing up; nothing rewards eating past your goal. There's no account, no ads, and everything you log stays on your phone.
Built like a game, honest like a logbook
Tracking protein is boring. Feeding a mascot who visibly grows with your day is not.
He grows as you log
Ten muscle groups inflate with your daily progress. Log 60% of your goal and Jack's carrying 60% of the pump.
Train a split, watch it fill
Pick today's groups — arms, chest, core, back, thighs, calves — and the muscles you trained flood molten gold as your day fills.
Goal-hit detonations
Hit your number and the celebration rips through him bottom-up — smoke blast or hero flames, with the Stars & Stripes waving behind him.
Streaks, XP, levels
Goal days bank full credit, partial days bank partial credit, and your level never goes backwards. Logging anything keeps the streak alive.
Your number, not ours
You pick the number — ideally with your provider — and Jack tracks it. The app doesn't ask your weight or choose a goal for you.
Nothing leaves your phone
No account, no ads, no data sale. No weight, calories, photos, or body stats — it doesn't even ask. Deleting the app deletes your data.
How it works
Set your goal
Choose your daily number, ideally with a physician, dietitian, or other qualified health provider. The app doesn't pick one for you.
Log as you eat
Drag the pump slider or tap a quick-repeat chip. Jack previews the growth about to land before you commit.
Hit it
The celebration detonates, the streak holds, and the XP banks. Come back tomorrow and do it again.
Three ways in
Pick whichever fits. Cheapest first, nothing preselected, no tricks.
Renews monthly until you cancel.
Renews yearly until you cancel.
Never renews. Nothing to cancel.
No free trial. Apple handles all payment; subscriptions renew automatically unless canceled at least 24 hours before the period ends, and are managed in your App Store account settings. The in-app Health & Safety screen — including crisis and eating-disorder support resources — is free for everyone, always, no purchase needed. See the Privacy Policy and Terms of Use.
Questions
Is there a free version or a free trial?
No. The app is a paid product with no free trial — $0.99/month, $9.99/year, or $30 once for lifetime. One thing is always free: the Health & Safety screen, with crisis and eating-disorder support resources, is readable by anyone without paying.
Does the app tell me how much protein to eat?
It doesn't pick a number for you. You set your own daily goal and Jack Steel tracks it, and the app doesn't ask your weight. Published reference values like the RDA are general figures for populations, not a personal recommendation; our article on the official numbers explains what they are. Settle your number with a physician, dietitian, or other qualified health provider.
Is this a clinical or medical product?
No. Jack Steel's Protein Tracker is a consumer wellness app for tracking a number you choose. It is not a medical device, it is not clinical software, and it has nothing to do with the clinical and professional work described elsewhere on wristskill.com. No licensed professional is acting in a professional capacity through this app or these pages, and using them creates no clinician–patient or dietitian–client relationship.
What happens to my data?
Everything you log stays on your phone. There are no accounts and no servers, no ads, and no data sale. The app sends only anonymous usage counts that carry no identity and none of your numbers. The full detail is in the Privacy Policy.
Who is the app for?
Ages 13 and up. It's a general-wellness habit tracker made for gym culture — not a medical device, and it makes no claims about your health. It deliberately has no weight, calorie, or body-composition tracking, no photos, and no leaderboards. If you're under 18, set your goal with a parent or guardian and a qualified health provider.
Is it on Android?
Not yet — Jack Steel's Protein Tracker is currently iPhone-only.
