Daily tactical fitness, simplified

One mission. One streak. No wasted motion.

Gruntz is a clean tactical training app for selection prep, readiness work, and hard events. Open the app, see today’s mission, complete the work, stack XP, and come back tomorrow.

Built For

Selection prep, readiness, and hard-event athletes.

The product positioning is narrow on purpose. Gruntz is not trying to be a broad wellness platform. It is built to keep tactical-style training structured and visible.

Selection Prep

Structure for people chasing hard standards.

Use Gruntz to stay inside a daily rhythm when you are preparing for selection, military readiness, or tactical schools.

Readiness

One mission per day beats vague motivation.

The app keeps the work tight: today’s mission, your streak, your XP, and the next block of progress.

Hybrid Events

Useful for OCR, rucks, and hard-event training.

Programs, movement cards, and run tracking stay focused on adherence instead of bloated wellness dashboards.

Mission Flow

The app loop stays sharp.

Gruntz is strongest when it keeps the user inside a simple repeatable cycle: program, mission, completion, progress, repeat.

01 Pick the program

Start with Raider or Recon and lock in the training lane that fits the mission.

02 Load today’s work

Open the command center, pull today’s mission, and move straight into the session.

03 Log the result

Complete the work, record the effort, and keep the streak moving forward.

04 Track the intel

XP, rank, history, and movement cards make it easy to see what is improving and what is lagging.

App Screens

Real screenshots from the product.

The site uses actual app images from the current build so the marketing layer stays grounded in the product instead of mockups or placeholder UI.

Core Value

Everything here supports the day’s work.

The design language follows the app: dark surfaces, high-contrast tactical accents, and direct information hierarchy instead of decorative noise.

Today

Daily missions built around adherence.

Gruntz is intentionally narrow. The product is meant to get someone into today’s work quickly and back tomorrow.

Progress

XP, rank, streaks, and mission history.

The progress model rewards consistency and makes it obvious when volume, streak, or total reps are slipping.

Programs

Raider and Recon training paths.

Program selection and progression are part of the core loop instead of being buried in settings or static PDFs.

Tracking

Run and ruck support when it matters.

Distance, pace, steps, and elevation are available for run-tracker sessions without turning the app into a generic activity feed.

Content

Workout cards and movement references.

Movement support is built in so users can review the day’s work, reference cards, and unlock progression without leaving the app.

Privacy

Local-first where it counts.

The current Gruntz app is designed so core training logic and saved progress stay close to the device. External services are limited and directly tied to billing or platform features.

  • The current app is primarily local-first for core training data.
  • No third-party advertising SDKs are used in the current build.
  • Billing and entitlement checks run through RevenueCat and the app stores.
  • Location and motion permissions are used only for fitness features that need them.
Does Gruntz require an account to use the core training loop?

The current build is designed as a local-first app. Core progress, settings, and mission state are stored on the device instead of requiring a mandatory social or cloud account for basic use.

What data leaves the device?

The main external service in the current app flow is RevenueCat for subscriptions and entitlements. Apple App Store or Google Play also handle transaction processing for in-app purchases.

Why does the app ask for location or motion access?

Location is used when someone chooses to track a run or ruck. Motion-related sensors such as pedometer and barometer support workout and run-tracker metrics where available.

Which links should I use for App Store review fields?
