### 5/5 — Great

*2026-05-12, version 7.4.66*

Amazing app, great projections especially on MLB picks. Literally the most ive been up in profit since I started using it. I just wish it was mire visually appealing but amazing app man. I think the monthly price is steep compared to others but hey , you make it back.

### 5/5 — Best tool

*2025-12-21, version 7.4.60*

Great company. I’ve been using at least 7 years. Makes dfs easy and fun.

### 2/5 — Optimizer

*2025-11-21, version 7.4.59*

I was trying to use the new Optimizer for the tiers and with extra settings, it wouldn’t let it generate any lineups

### 5/5 — Great help

*2025-08-31, version 7.4.56*

Eliminates the extra research

### 1/5 — Ownership is trash

*2025-08-23, version 7.4.56*

Good statistics but they have no idea what they are doing when it comes to player ownership pretty much the very most important thing in daily fantasy. Unreliable garbage!

### 1/5 — Bad App…No profits

*2025-07-23, version 7.4.53*

This app will cause you to lose majority of your wagers….very inconsistent where it says player have good matchup they do poorly vise versa and when it say players have bad matchups they out performs everyone else on the team. Just save your money on this app…totally complete money scam for the price

### 1/5 — App is not functional on iMac

*2024-11-22, version 7.4.46*

Linestar app is not functional on an iMac - when you open the application all you see is program code and an error message - please fix.

### 1/5 — Horrible projections

*2024-11-17, version 7.4.46*

If you need help donating money, and you rather not donate it to god or charity. This app has you covered. Best app for horrible projections. Guaranteed to make you lose money.

### 1/5 — Letdown

*2024-11-07, version 7.4.46*

This App has a lot of Information about everything from the Weather to Injuries. It just lacks the most important thing needed for betting, probabilities. It has no Probability Scores and no way to track it’s historical accuracy. Don’t waste your money, it’s just smoke and mirrors.

### 3/5 — Needs better server

*2024-10-13, version 7.4.42*

If you wait for NFL active players to come out the app will crash. Not the best app for Sunday mornings.
