### 1/5 — Does nothing. Has never done anything.

*2026-04-13, version 2.0.8*

if I can credit this company and its software team with anything, I can credit them with consistency. For many many years now, they’ve been consistently and profoundly incompetent. This company seemingly just doesn’t care about its customers, and I would search for other manufacturers, if you want to actually link your data to something useful.

### 1/5 — Can’t even set up profile

*2026-02-28, version 2.0.8*

Keeps telling me there is an internet failure when hitting the Save button. Very glitchy and unpolished.

### 1/5 — Useless

*2026-02-25, version 2.0.8*

App does not work. Absolutely useless! Big waste of time.

### 1/5 — Does not work at all

*2026-02-25, version 2.0.8*

Like everybody else, this app doesn’t work. I can’t get my profile because of “internet issues”. 
Why even bother with the effort of making an app if you’re not even going to make sure it works or fix it after months of people complaining? Seriously, either the company or Apple should just remove this at this point. It’s an embarrassment.

### 1/5 — Total Garbage

*2026-01-04, version 2.0.8*

I sold a Lifespan TR4000i and had to pay extra for Bluetooth module for connectivity to my iPhone for tracking.  To this day I have never had an anything work reliably or at all. Pure vapor ware.

### 1/5 — Doesn’t function

*2025-12-14, version 2.0.8*

Will not get past the edit user page. Reports “Internet issues”!

### 1/5 — Absolute trash

*2025-12-08, version 2.0.8*

Sooooo glad I dropped $2.5k on gym equipment with Bluetooth only to find out they don’t make a functional app to use the Bluetooth.  Seriously, it won’t even let me log in.

### 1/5 — Super buggy.

*2025-11-06, version 2.0.8*

Super buggy. It is easy to lose the walking data. No ideas why it often set steps to 0 and failed to sync.

### 1/5 — Garbage

*2025-10-26, version 2.0.8*

See title.

### 1/5 — Horrible

*2025-08-22, version 2.0.8*

Makes me regret buying Lifespan underdesk treadmill
