What's New in Protocol

17

August 9, 2026

A rebuilt interface that starts simple and grows with you. EARNED COMPLEXITY TODAY opens with only what you need to act on now. Coach intel, adaptive TDEE and the full chronicle stay out of the way until you've built the history that makes them useful, then unlock as you go. CLEANER TABS FUEL puts calorie cycling one tap from the cycle pill. TRAIN drops a redundant sub-tab and keeps your session front and centre. YOU collects settings, benchmarks and your chronicle in one place instead of three. BUILT FOR ONE HAND Save and Cancel now sit at the bottom of the meal editor, in thumb reach, and stay visible while you review a scan. Number fields open the number pad with a Done button. Long-press actions and menus replaced buried screens. READABLE AT ANY SIZE Text across the main screens scales with your iOS text-size setting. Every style was raised to a legible minimum and recoloured to meet WCAG AA contrast, so the dense screens stay readable in real light. Sheets now grow with the text inside them, so a larger font no longer breaks their layout. RESPECTS YOUR SETTINGS Reduce Motion switches off ambient animation throughout the app. Times follow your device's 12- or 24-hour preference, and dates follow your region. HONEST PRICING Anyone outside the US could see dollar figures that weren't what Apple would charge. Every price, saving and per-day figure now comes from the App Store for your region. SEE WHAT OPERATOR ADDS Satiety, micronutrient tracking and coach intel used to be simply absent on the free plan rather than locked. You can now see what they are and what they'd show you. THE DAILY BRIEF HAS BEEN RETIRED The morning reel is gone. Everything it showed lives on TODAY and FUEL, and your compliance history is untouched. FIXES - Protocol Reset now restarts your day count and calibration, instead of leaving both running from your original start date - Fixed a visual jitter on TODAY after a fresh install - Day rollover is correct across midnight, time-zone changes and DST - Failed body scans tell you what happened instead of failing silently - Corrected the app icon badge count - Removed a stray empty bar and a duplicate close button in the meal editor

Best AI Coach in the App Market

The meal scanner got me to try it, but the coaching is what makes me keep using it. It helps me see if I’m actually staying on track instead of just logging random numbers.

Great app alternative

Coming from the app Hevy and Strong, Protocol feels more of a full system. Logging lifts, track my personal records etc.

Been using this app for months

I’ve been following this app protocol since they started development. Since the developer is solo id understand there will be some setbacks for updates and improvements compared to bigger teams. But every update the app always improves and strives towards a better direction. I never really wrote reviews before but this app really deserves it. It’s free but it’s really worth paying for! Meal scanning is so polished , body scans with adaptive protein intake is such a game changing feature for an app like this. Protocol will be the future of fitness apps. If you haven’t downloaded it yet , I suggest you try the 7 days free trial that’s going on right now!

All in one!

I like that the app focuses on compliance instead of temporary motivation. I love that that I can ditch 3 apps and just use 1. What else has tracking steps, meal logging/tracking calories, and solid workout plans instantly? I highly recommend Protocol.

Response from developer

Thank you so much for the kind words! I’m thrilled that Protocol's all-in-one approach is working for you. You nailed exactly what I set out to build. Compliance over motivation, because consistency is what actually gets results.

Ive never seen anything like it

Has every feature you would want and think off you need to try it out for yourself highly recommended!! 😌😌
