### 1/5 — Daily erg WOD not loading correctly

*2026-08-29, version 2.16.2*

Been using ErgData since it’s inception with no problem. For the past few weeks, the daily WOD is loading like a straight row not an interval. Very annoying.

### 4/5 — Need to fix session syncing to apple fitness

*2026-08-28, version 2.16.2*

Had a good time with ErgData but unfortunately the session sync to Apple fitness seems very unreliable. I am consistently needing to enter data manually even after reinstalling the app enabling and re-enabling Apple health data several times and clicking through the acceptances. This was not a problem before latest updates

### 3/5 — No longer updates Apple health automatically

*2026-08-28, version 2.16.2*

It stopped sharing w apple health on 7/15.  No settings changed, everything still enabled to share.  No data sync

### 5/5 — Best app from the best American company ever

*2026-08-27, version 2.16.2*

Receptive to input from users, but works flawlessly until it doesn’t then lo and behold an update is ready for install. Socially conscious company that makes a top notch bombproof product. Can you tell I’m a fan?

### 1/5 — Garbage

I refuse to give up.

### 2/5 — Missing interval data and glitches

*2026-08-23, version 2.16.2*

The last update has resulted in missing interval analyses, parts of the workout title is missing, 
Needs a new release to fix.

Been using this app for years- great features, great daily workouts, great interactive features and ranking. -A+++
