Question 1

What is Watta?

Accepted Answer

Watta is a rowing training log app that lets you capture workout data by photographing your Concept2 erg screen. Watta analyses your workouts and gives you an Effort Score so you can track your training load over time.

Question 2

How do I log a workout?

Accepted Answer

Tap the + button, take a photo of your erg screen (or choose one from your camera roll), review the extracted data, and tap Save Workout. The app reads the data from your photo automatically, and you can edit any value before saving. You can also skip the photo entirely and enter data manually.

Question 3

What is the Effort Score?

Accepted Answer

The Effort Score (0-100) measures how hard your workout was, personalised to you. It combines Cardiac Load (heart rate intensity, when available), Work Output (power and duration adjusted for your body size), Pacing (a consistency bonus for even or negative splits), and Economy (stroke efficiency). Scores fall into four zones: Recovery (0-25), Building (26-50), Training (51-75), and Peak (76-100).

Question 4

How is my Effort Score personalised?

Accepted Answer

Your score is calculated using your profile data: age, weight, height, max heart rate, and resting heart rate. A 2:00 split means different things for different people — Watta adjusts for that. Keep your profile up to date in Profile → Edit Profile for the most accurate scores.

Question 5

Do I need a heart rate monitor?

Accepted Answer

No, but it helps. Without heart rate data, Watta estimates your cardiac load from power output. With heart rate data, your Effort Score is more accurate and you unlock full Heart Rate Analysis.

Question 6

Why is my distance or time wrong?

Accepted Answer

The app uses AI to read your erg screen photo, and it can make mistakes — especially if the photo is blurry or at an angle, there is glare on the screen, or the screen shows many numbers at once. Always review the extracted data before saving; you can tap any field to edit it.

Question 7

Can I edit or delete a workout after saving?

Accepted Answer

Yes. Go to Workouts, tap the workout, then tap Edit to change any value or Delete to remove it.

Question 8

What types of workouts can I log?

Accepted Answer

Distance pieces (for example 2000m or 5000m), time pieces (for example 10:00 or 30:00), and interval sessions (for example 7×500m or 4×1000m). Watta supports the RowErg, SkiErg, and BikeErg.

Question 9

Can I log workouts manually, without a photo?

Accepted Answer

Yes. Tap +, choose Manual Entry, and type in your data.

Question 10

What is the difference between split and time?

Accepted Answer

Split is your pace per 500m (for example 1:55.0/500m). Time is the total workout duration (for example 20:00.0). If your split is 2:00 and your distance is 2000m, your total time is 8:00.

Question 11

What is Heart Rate Analysis?

Accepted Answer

When you log heart rate data, Watta provides additional insights: Intensity (what percentage of your max heart rate you worked at), Zone (which training zone you were in), Efficiency (watts produced per heartbeat), and Cardiac Drift (how much your heart rate rose during the session — a fatigue indicator).

Question 12

What are heart rate zones?

Accepted Answer

Watta calculates personalised zones using the Karvonen method (heart rate reserve): Z1 Recovery (very easy, could chat), Z2 Aerobic (comfortable, breathing steady), Z3 Tempo (challenging, short sentences), Z4 Threshold (hard, only a few words), and Z5 Max (all out, cannot talk). Zones are based on the max and resting heart rate in your profile.

Question 13

How do I record my heart rate?

Accepted Answer

Watta reads heart rate from your erg screen photo when it is displayed — pair your heart rate monitor with the PM5 and it appears on screen. You can also enter your average heart rate manually when reviewing a workout.

Question 14

How do I join a club?

Accepted Answer

Go to the Clubs area, search for your club name, and tap Request to Join (or enter your club invite code). A club admin then approves your request.

Question 15

How do I create a club?

Accepted Answer

Go to the Clubs area, tap Create Club, enter your club name, location, and description, and submit. New clubs start as pending until verified by the Watta team.

Question 16

What is the difference between a club and a squad?

Accepted Answer

A club is your rowing club (for example "London Rowing Club"). A squad is a group within your club (for example "Women's Squad" or "Novices"). You can be in one club but multiple squads.

Question 17

Who can see my workout data?

Accepted Answer

You control workout visibility: private workouts are visible only to you, while public workouts can appear in your club, squad, and followers' feeds and on leaderboards. Visibility is set per workout, and your profile privacy settings control what club members can see.

Question 18

Can my coach see my data?

Accepted Answer

Only with your consent. Coaching in Watta is built on a mutual invite: you and your coach connect from the Profile screen, and you choose whether the coach sees your full workout history or only the workouts attached to their assignments. You can change or revoke this at any time.

Question 19

How do I connect Strava?

Accepted Answer

Tap the + button to open Add Workout, choose Share to Strava, then log in to Strava and authorise Watta. Once connected, your workouts appear in your Strava feed as rowing activities.

Question 20

How do I disconnect Strava?

Accepted Answer

Go to Add Workout, tap Share to Strava, and choose Disconnect.

Question 21

Can I import workouts from ErgData?

Accepted Answer

Yes. Workouts you record with ErgData sync to your Concept2 Logbook, and Watta can import them from there. Tap the + button, choose Import from ErgData, and authorise Watta with your Concept2 Logbook account. Your workout history imports automatically, and new workouts flow in each time you open the app.

Question 22

How do I disconnect my Concept2 Logbook?

Accepted Answer

Go to Add Workout, tap Import from ErgData, and choose Disconnect. Workouts already imported are kept.

Question 23

How do I change my password?

Accepted Answer

Go to Settings and use Reset Password — we email you a secure link to set a new one. If you signed up with Apple or Google, your login is managed by that provider instead.

Question 24

How do I update my profile (age, weight, etc.)?

Accepted Answer

Go to Profile → Edit Profile. Keeping this up to date improves your Effort Score accuracy.

Question 25

How do I delete my account?

Accepted Answer

Go to Settings → Delete Account. This permanently deletes your account, removes all your workout data within 30 days, and removes you from any clubs. This cannot be undone.

Question 26

Is Watta free?

Accepted Answer

Yes. Watta is free to download and use — logging workouts, the Effort Score, heart rate analysis, clubs, and squads are all included.

Question 27

What data do you collect?

Accepted Answer

In summary: account info (email, name), profile data (age, weight, height, heart rate), workout data (distance, time, split, heart rate), and usage analytics if you consent. See our Privacy Policy at getwatta.com/privacy for full details.

Question 28

Do you sell my data?

Accepted Answer

No. We never sell your personal data to third parties.

Question 29

How long do you keep my data?

Accepted Answer

We keep your data while your account is active. If you delete your account, we delete your data within 30 days.

Question 30

How do I request my data or ask you to delete it?

Accepted Answer

Email privacy@polarindustries.co with your request. We respond within 30 days.

Question 31

The app won't read my photo

Accepted Answer

Make sure the photo is clear and well-lit, avoid glare on the erg screen, and take the photo straight-on rather than at an angle. Then try again — AI isn't perfect. You can always enter the data manually instead.

Question 32

The app crashed

Accepted Answer

Close and reopen the app, check for updates in the App Store or Play Store, and restart your phone. If it keeps happening, email support@polarindustries.co with your device model and OS version.

Question 33

My Effort Score seems wrong

Accepted Answer

Check that your profile is up to date — age, weight, max heart rate, and resting heart rate all feed the score. Also check the workout data itself (distance, time, split) was read correctly from the photo.

Question 34

I can't log in

Accepted Answer

Check your email and password are correct, tap Forgot Password to reset, and check your internet connection. If you're still stuck, email support@polarindustries.co.

Question 35
