What Makes It Different

Built for People
Who Know What They're Doing

Diet & Training in One Loop

Your nutrition and training program live in the same app and understand each other. Carb cycling and refeeds are first-class citizens.

Serious Protocols

Long running periodization, planned deloads, rest-pause work, carb cycling, refeeds. Built for people who need more than vibes.

You Know Better Than Some AI

No AI picking your sets. No algorithm optimizing your macros. You author the program. The app helps you stick to it and gets out of the way.

Gold Stars Are for Children.

Zero motivational notifications. Zero streak counters. If you need an app to tell you to go to the gym, this is not your app.

Your Data, Your Device

Local data only that you control. No selling your habits to advertisers, no login screen. We can't see your data and we don't want to.

No Subscription. Ever.

No monthly fee. No premium tier bullshit. No features locked behind a paywall you discover after you have already moved your whole training life into the app.

The Desktop App

Korivo Studio

The phone is for training. Studio is for building. A full peer, not a viewer, running the same engine on the same plain files.

Mac · Windows · Linux | Same folder as your phone | Included, not extra.

Formula Constructor

Protein scales by body-fat band. Drag the boundaries instead of writing a conditional. Every tier resolves live underneath.

Korivo Studio progression editor: a training block above three session curves, each with a draggable dot for every time that session runs.

Progression Is a Shape

One dot per time the session runs. Drag any dot. Shift-drag the whole curve. Everyone else makes you type this.

Program Map

Training and the diet coupled to it, on one ruler, with this week underneath.

Korivo Studio meal plan constructor: meals as dots on a timeline with per-meal foods, alternates, and live daily totals.

Meal Plans

Meals are dots on the day. Drag to retime. Foods carry alternates, totals track live.

Explore

Actual weight and reps, never an estimated 1RM. Every field on the left is a series you can lay over any other, including your bloodwork.

On iPhone

Just the Work.

Home

Your week, your macros, today's session, your biometrics. Everything at once. Nothing to scroll.

Korivo logging a rest-pause set: subset two of three at 135 lb, with a fifteen second rest queued.

Training Log

Mid rest-pause set. Subset 2 of 3, weight carried across, the 15 second rest queued up next.

Korivo set editor showing a rest-pause subset ladder: eight reps, fifteen seconds, four reps, fifteen seconds, three reps.

Build the Set

A real subset ladder. 8 reps, rest 15s, 4 reps, rest 15s, 3 reps. Prescribed, not improvised.

Korivo program editor showing a two-phase program with a six week heavy block and a two week volume block.

Build the Block

Phases with their own length, workouts, and weekly set volume. Edit the whole thing from your pocket.

Korivo diet editor showing a cyclical ketogenic diet with five keto depletion days and two carb refeed days, each driven by a formula.

Day Types

Five depletion days, two refeeds, 30g carbs against 707g. Every number comes from a formula.

Korivo insight detail explaining why it fired, showing protein-adherent days two of five against a threshold of three.

Insights

Every insight shows why it fired and the data behind it. It tells you. It never changes your plan.

Under the Hood

The Stuff Other Apps
Don't Know Exists

Diet Engine

Fixed, cyclic, workout-aware, formula-driven, or a full meal plan
Macros resolve per day from the session you are actually doing
Carb cycling with depletion, load, and maintenance days
Formula expressions: protein = bodyweight × 2.2
Floors and ceilings enforced, not suggested
Offline food database, barcode index, on-device label scan

Training Engine

Rest-pause, myo-reps, drop sets, AMRAP, widowmakers, timed holds
Wave loading, percentage blocks, ramps, autoregulation, auto-deloads
Phases that advance on a PR or a stall, not just a date
A rules engine that composes conditions into adjustments
First-class cardio with intervals and zones

Phases & Progression

A Program That
Changes As You Do

Phases advance when you hit the milestone. Not when the calendar says so.

Most apps hand you a static routine and a separate macro number that never move. Korivo runs your program in phases, and training and nutrition each get their own. A lean bulk runs for months. The mesocycles inside it turn over every few weeks. Neither has to wait for the other.

Inside a block, progression drives the load. Wave it, ramp it, autoregulate it, or climb toward a rep max across the whole phase, with the deload already built in.

Between blocks a transition fires: on a duration, on a PR, on a stall, or on whichever lands first. A block you are still growing in does not end because a calendar said five weeks.

Two lanes, one program. A lean bulk spans months while the mesocycles inside it turn over every few weeks. Boundaries are independent, and a transition can fire on a milestone instead of a date.

Korivo is a one-time purchase, not a free app. You pay once and never again. Competitor pricing and features as publicly listed, July 2026; RP sells training and diet as separate subscriptions and the figure above is training only. Corrections welcome; we would rather be accurate than flattering.

Why Korivo™ Exists

I Miss Old School
Gym Culture

I've been lifting for 25 years. I grew up on the early bodybuilding forums: Avant Labs. Elite Fitness. Lyle's board. WannaBeBig. That era had something the modern fitness internet has completely lost: no-bullshit, evidence-based thinking from people who actually trained hard. Sponsored posts didn't exist. Algorithms didn't curate your feed. Nobody was trying to sell you a coaching program.

That culture is mostly gone. What replaced it is worse in every measurable way. Influencers. Fitness apps that hold your hand, gamify your workouts, and charge you $15 a month to tell you to “stay consistent.”

None of them speak the language of someone who actually knows what DoggCrapp training is or wants to run UD2.0.

Korivo is my attempt to build something that would have felt at home in that era: a tool for people who already know what they're doing and just need the app to get out of the way.
