Erg tracking built for military standards

By the Watta Team · Updated 10 August 2026

Military fitness demands consistent, measurable performance on the ergometer. Watta gives you AI-powered workout logging from PM5 screen photos, Effort Scores that benchmark every session objectively, and club features to track your entire unit — whether you are training on base or deployed.

Rowing App for Military Fitness: 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

Tracking erg times for fitness assessments is manual and inconsistent

PT tests and fitness assessments require accurate erg data, but results are recorded on paper, whiteboards, or scattered spreadsheets. Historical performance is difficult to retrieve when it matters most.

No good way to compare performance across a squad or unit

Unit fitness depends on every member hitting benchmarks. Without a shared platform, PTIs and NCOs have no visibility into who is training, who is improving, and who needs support.

Manual logging does not survive the pace of military life

Between duties, deployments, and training rotations, there is no time for detailed workout journaling. Data entry falls off quickly, and months of training history disappear.

How Watta Helps

Effort Score for Consistent Benchmarking

The 0-100 Effort Score provides a single, objective number for every erg session. Use it to benchmark PT performance, track readiness over training blocks, and set clear standards across a unit.

Frequently Asked Questions

Can Watta be used to track erg results for military PT tests?

Yes. Watta logs every erg session with full detail — split, distance, time, stroke rate, and heart rate. You can review historical performance and track improvement leading into PT assessments.

How does the club feature work for a military unit?

Create a club for your unit, generate an invite code, and share it with your personnel. Organise members into squads to mirror your unit structure. All logged workouts appear in the club feed, giving PTIs and commanders full visibility.

Does Watta work without internet access?

Watta requires an internet connection to process PM5 screen photos via AI and sync data. However, photos can be taken and uploaded later when connectivity is available.

Is the Effort Score useful for comparing different types of erg workouts?

Yes. The Effort Score normalises across workout types — steady state, intervals, and test pieces all produce a comparable 0-100 score. This makes it easy to track training load regardless of session format.
