### 5/5 — Massive Potential

*2025-08-23*

I’ve been a user of Fantasy Labs on and off since 2015. Seeing a mobile version of Simlabs is groundbreaking! Fantasy Labs has always been solid and this is a great idea!

### 5/5 — Best sim in fantasy

*2024-10-21*

Best most winning site

### 5/5 — Easiest way for a good sweat

*2024-10-15*

I’m using this to create 20 or 150 lineups (whichever the max) specifically for island NFL games. It is so easy and having an app makes it extremely convenient. Good stuff 👍

### 5/5 — Great DFS Product

*2024-09-11*

Been loving using this sims product for me NFL lineups. I finished 5th in a recent NFL Showdown simply using this tool. It’s easy to generate lineups and upload them to DraftKings.

### 5/5 — So good.

*2024-08-15*

Truly is the easiest building experience yet for DFS

### 5/5 — Faster. Better. Easier.

*2024-07-31*

Love this app and the SimLabs product in general. I’ve always been more of a hand-build single entry player, but this lets me build smart and unique lineups super efficiently, even for sports I know nothing about. 10/10
