Train together, track together

By the Watta Team · Updated 10 August 2026

Rowing side by side is one of the best partner workouts — but without shared data, there is no friendly competition and no way to celebrate each other's progress. Watta lets couples log erg sessions to a shared feed, compare Effort Scores, and motivate each other with leaderboard rankings.

Rowing App for Couples: Watta is a free, AI-powered rowing workout tracker. Snap your erg screen to capture data instantly. Get a 0-100 Effort Score combining cardiac load, work output, pacing, and economy. Track heart rate zones via the Karvonen method. Join clubs and squads to train with your crew.

The Problem

Partner workouts lack shared tracking

Most fitness apps are designed for solo use. Couples who train together cannot easily compare sessions, track each other's progress, or compete on the same leaderboard without awkward workarounds.

Different fitness levels make comparison unfair

Raw split time comparisons between partners of different sizes and fitness levels are meaningless. Without a normalised metric, the faster partner always "wins" and the other feels discouraged.

Motivation fades without accountability

Couples often start exercise routines together and then drift apart. Without shared goals, visible progress, or gentle competition, it is easy for one or both partners to lose consistency.

How Watta Helps

💑

Shared Club Feed

Create a private club for just the two of you. Every workout appears in a shared feed — see each other's sessions, Effort Scores, and streaks without leaving the app.

⚖️

Fair Effort Comparison

The Effort Score normalises session quality across body weight and fitness level. Both partners get a fair 0-100 score that measures how hard they actually worked — not just who rowed faster.

🔥

Streak Motivation

Watta tracks weekly training streaks. Challenge your partner to maintain a longer streak and celebrate milestones together. Nothing builds consistency like friendly accountability.

How It Works

Snap your erg screen

Take a photo of your PM5 display after your workout. Gallery upload works too.

AI extracts your data

Watta reads every metric — time, split, distance, stroke rate, heart rate, and calories.

Get your Effort Score

A 0-100 score combining cardiac load, work output, pacing, and economy shows exactly how hard you worked.

Frequently Asked Questions

Can my partner and I see each other's workouts?

Yes. Create a club on Watta and invite your partner with the invite code. Both of your erg sessions will appear in the shared club feed, complete with Effort Scores, split times, and distances.

Is the Effort Score fair for different fitness levels?

Yes. The Effort Score accounts for body weight in the work output component and uses personalised heart rate zones. Two partners at different fitness levels can both score 70 if they each worked at an appropriate intensity for their own capacity.

Can we do the same workout and compare results?

Absolutely. Row the same distance or time, then compare your Effort Scores in the shared feed. The score measures session quality rather than raw pace, so the comparison reflects genuine effort regardless of who finished faster.

Every erg counts.
