Thinkorswim App Review
If you want to enjoy the benefits of mobile trading, you already know how important a trading app is. Being able to manage your positions, place trades anywhere, and follow stocks on your watchlist without needing a computer is a major advantage.
Thinkorswim account holders can use a powerful mobile trading app designed to deliver a full trading experience while on the go. The Thinkorswim app works on Android, iPhone, and iPad devices.
Is the Thinkorswim app worth using? Let’s take a closer look and find out.
Thinkorswim (TOS) App Overview
The Thinkorswim mobile app works well across many devices, and the trading experience is nearly identical on all of them. While screen size and resolution can affect the layout, the same tools are available regardless of the device.
The main difference between devices comes down to processing speed. Newer and more powerful devices naturally run the app faster.
For example, trading on an older Samsung S9 still runs smoothly, showing that the Thinkorswim app is optimized to perform well on a wide range of devices.
Thinkorswim App on iPhone
The Thinkorswim app for iPhone is fast and benefits from Apple’s strong processors. It handles charts with multiple indicators easily, and switching between screens or menus is quick. The user interface on iPhones is clean and simple to navigate.

Thinkorswim App on Android
The Thinkorswim Android app has the same features as the iPhone version. You can log in using biometrics and switch between paper and live trading accounts at any time.
The iPhone version looks slightly more polished, as it seems to receive more visual updates, but the Android version is just as capable.
Thinkorswim App on iPad
The iPad version includes all the same tools as the iPhone app but benefits from a larger screen and more processing power.
With processors like the M1 chip, the app runs extremely well on any iPad model. Whether using an iPad mini, Air, or Pro, the Thinkorswim app performs smoothly.
External accessories such as keyboards and styluses also improve usability and make the experience even more flexible.
Thinkorswim App on Tablets
The experience on Android tablets can vary depending on the device.
Newer tablets with strong processors and high-resolution screens will run the app just as smoothly as an iPad, while older or budget tablets may perform slower.
As long as your tablet is up to date and powerful enough, you can expect excellent performance from the Thinkorswim app.
Thinkorswim App on Apple Watch
The Thinkorswim app also works on the Apple Watch. While its functionality is limited, it’s useful for checking markets, monitoring watchlists, and viewing your positions.
The newer Apple Watch models are especially handy thanks to their larger screens.
A unique benefit of using the Apple Watch while trading is the ability to track your physical state—if your heart rate rises, it might be a good time to adjust your risk.
TOS App Features
The Thinkorswim app makes all its tools easy to access. Navigation is simple, and traders at any experience level will find it intuitive to use.
All features are available through the main menu, chart screen, or order entry panels.

I work in investment analytics and have been investing in the market since I was in high school. I enjoy anything that involves lots of strategy (i.e. a good game of chess), which is why I was naturally drawn to investing and researching companies. Outside of investing, I’m a big fan of the outdoors. In summer, you’re most likely to find me kayaking, camping, and hiking in the mountains.
