Observed work stays observed
Stroke-level data becomes a field of real pace moments rather than an invented smooth line.

One rowing loop
From training intent to a row you can understand.
aftererg keeps intent, execution and history together, without turning your training into a score. It lets you focus on your performance without comparing yourself with others. Your history and intent provide the context and competition.

The new pace profile
A row is a sequence of strokes, not an average pace.
The temporal pace profile keeps the recorded clock, separates recovery and places the current row against a like-for-like blue ghost.
Your own history becomes the ghost
Comparable sessions sit on the same represented clock, making pacing and finishing shape easy to read.
Missing detail remains visible
Sources do not all record the same evidence. Gaps, recovery and partial tails stay honest.
Navigate your history
A Logbook you can navigate.
Downloaded rows and local captures become one explorable history, with several ways to find the session that matters.
Season heatmap
Move from training rhythm to a day and then into the rows behind it.
Efficiency map
Explore pace against rate, select a point and open the workout it represents.
Comparable sessions
Group rows by distance, structure and workout identity so like stays with like.
Last workout
See the latest effort in recent and seasonal context as soon as it lands.
Built around real rowing data
Rich when the evidence is rich. Honest when it is sparse.
A local capture can carry every stroke. A downloaded Logbook result may contain detailed telemetry, interval summaries or only totals. aftererg uses the strongest available evidence without pretending every source is identical.

Private by design
Your rowing data stays yours.
Limited logbook access and local-only mode
aftererg reads workouts with your permission. It writes a finished capture only when you turn on auto-save, which is off by default, and never rewrites rows already in your Logbook.
Local-first capture
Rows captured by aftererg appear immediately and remain useful before any network round trip.
Sharing stays deliberate
Your analysis remains private unless you choose to create and share something from the app.
Questions
Before your next row.
Does aftererg work with a Concept2 PM5?
Yes. A compatible PM5 can connect over Bluetooth for live capture and workout programming. You can also use the app with downloaded Logbook history.
Does aftererg connect to the Concept2 Logbook?
Yes. aftererg reads workouts with your permission. It writes a finished capture only when you turn on auto-save, which is off by default, and it never rewrites rows already in your Logbook.
Does aftererg replace ErgData?
It takes a different role. aftererg brings programming, local capture, comparison and reflection together. Rows already recorded by ErgData can still arrive through your Concept2 Logbook.
What can I programme?
Distance, time and calorie pieces; fixed and variable intervals; and recovery are available free. aftererg Plus adds pace and rate targets, internal segments, bursts and per-piece editing.
Is aftererg a coaching app?
aftererg is a personal evidence layer. It describes your own rowing history and comparisons without population rankings or prescriptive coaching claims.
Can I use it on iPhone and iPad?
Yes. The app adapts the live rowing and history experience for iPhone and iPad.
Can I send a workout to someone else?
Yes. Export a workout or plan file and send it through AirDrop, Messages, Mail or a shared folder. The recipient can open and read every session, target and note for free. Saving and following a plan is part of aftererg Plus.
Can I get my workouts out of aftererg?
Yes. Export one saved row, a plan with its rows, or the whole library as a versioned file that another copy of aftererg can read.
How does heart rate reach aftererg?
Pair a strap with the PM5 and the monitor passes its reading to aftererg, or start the aftererg Apple Watch app and send heart rate to your iPhone. aftererg does not pair directly with a strap.
Do I need an Apple Watch?
No. A strap paired with the PM5 works, and live capture works without heart rate. The Apple Watch app is another route for rowers who prefer it.
Does aftererg write to my Concept2 Logbook?
Only when you turn on auto-save. It is off by default. When enabled, it sends each confirmed capture; it never rewrites rows already in your Logbook.
Does aftererg work with Apple Health?
No. The iPhone and iPad app does not read from or write to Apple Health. The companion Watch app reads heart rate during an active rowing session and relays the current reading to aftererg.
Do I need a Concept2 account?
No. You can programme workouts and capture a row directly from a PM5 without a Concept2 account. Connect the Logbook when you want downloaded history or optional auto-save.
What is included in aftererg Free and aftererg Plus?
aftererg Free includes your Logbook, every row in full, live PM5 capture, a suggested row each day and replay of your latest row. aftererg Plus adds like-for-like comparison, season and year views, Row Again on any row, plans and detailed workout authoring. See the full comparison.
Where is my saved workout library stored?
On your device as local files. The saved workout library has no separate account or cloud sync, so exporting the whole library creates a useful backup.
