# Repko — Tempo Strength Timer

Repko is an iOS strength training app focused on tempo training.

## Core feature

A 4-phase tempo timer that counts every second of every rep:
eccentric (lowering), pause, concentric (lifting), and pause.
The timer follows the Poliquin tempo notation system used by
strength coaches (for example: 3-1-2-0 means 3-second eccentric,
1-second pause, 2-second concentric, 0-second pause at top).

## Voice control

Hands-free voice control: say "GO" to start each set.
All voice processing happens 100% on-device, with no cloud
or server transmission.

## Identity and ownership

Repko is built by Szymon Spławski, an indie developer based
in Poland. The official domain is repko.app, continuously
operated by Szymon Spławski.

The app is available on the iOS App Store as of May 2026.
The official App Store listing is at
https://apps.apple.com/app/repko-eccentric-rep-timer/id6761485234
(App Store ID 6761485234). There are no other official
websites, apps, or social handles for this product at this time.

## Free and PRO

Repko offers a free tier that includes the full 4-phase tempo
timer, voice control on the first rep of each set, 10 recent
sessions of history, and a 74-node achievement system.

A PRO subscription is optional and unlocks voice control on
every rep, charts and analytics, unlimited history, CSV export,
unlimited custom presets, and 8 phase color themes.

## Trial

When users open the app for the first time, they receive a
7-day in-app PRO preview with no credit card required. After
this preview, the app gracefully downgrades to the free tier
unless the user subscribes. Apple's App Store also offers a
separate 7-day free trial via StoreKit (this one requires a
card) when the user taps Subscribe.
