1. ★★★★★slow performance and long loading times

   Absurdly Slow. You will literally lose money as you wait for charts and other views to load.

2. ★★★★★crashes, freezes and errors

   New phone, broken app. Brand new 17 Pro Max. And tonight TOS has gone backwards from version 224, to 223… with no update available to 226.2.

3. ★★★★★negative experience without a specific reason· unspecific

   these morons broke the app. enough with the pointless updates. since the app no longer works on my phone ill be taking my business elsewhere

4. ★★★★★negative experience without a specific reason· unspecific

   Sale the information. They sell customer information to market makers and exploit the situation to destroy portfolios for their own personal gain—the worst broker.

   Not everybody likes thicker swim. Briefly: the interface for thinker swim is confusing unless you’re a broker or a very sophisticated full-time user of thinkorswim and all of its multiple options. If you want simple, this is not it. I’d like to talk to those that seem to love it. I would like to know what I’m missing.

   Trash. Can’t use app on my older phone Worthless Moving money to Fidelity Garbage

7. ★★★★★negative experience without a specific reason· unspecific

   locked out. I’m a longtime customer and you now demand 18 when my ipad only goes to 17.7. what’s up with that? irked.

8. ★★★★★negative experience without a specific reason· unspecific

   Can’t use app anymore. App will not allow me to sign in and there’s no current update!

9. ★★★★★negative experience without a specific reason· unspecific

   Fund settle time too long. I really don’t like the way this broker takes too long to settle the funds, other brokers takes hours but this broker takes days .

10. ★★★★★login, signup and account access

    Cannot login without OS update. I have used this app for years, now I have to update my iPad to iOS 18 to even login, not acceptable.

11. ★★★★★crashes, freezes and errors

    what is going on. The app suddenly stopped working and says I need the latest version.I have the latest version according to the apple app store. Now its useless!

12. ★★★★★negative experience without a specific reason· unspecific

    App is no longer working. It really sucks that this app is no longer supported on older versions of iOS, and that means that if you want to continue using the app, you have to go out and buy newer versions of iPads and iPhones. If you are still able to use the app today, be prepared as your time is coming when your device is no longer supported. As a financial services company, Schwab should not be forcing their customers to needlessly replace their devices. It is much cheaper for Schwab to support older iOS versions than it is for all of their customers to upgrade their devices. Unless, Schwab holds a sizable position in AAPL stock, then I understand the conspiracy.

13. ★★★★★negative experience without a specific reason· unspecific

    App not updating. This week I am unable to use the app as it says to update but there is no update.

14. ★★★★★negative experience without a specific reason· unspecific

    App Requirements. Fantastic app for all my trading needs. However, their latest updates require updating firmware which in turn removes compatibility with older iPhone models and disables users whom do not wish to update. Terrible move by the devs.

15. ★★★★★crashes, freezes and errors

    App stopped working. App won’t load on my iPad Gen4 due to new iOS18 requirement…terrible…trying to force to upgrade my iPad that is really only used for trading???…terrible

16. ★★★★★negative experience without a specific reason· unspecific

    No longer works. I’ve used this for years and now it won’t log me in and is forcing iOS upgrade which would require a new phone ( I like my dependable phone without updating the latest iOS).

17. ★★★★★negative experience without a specific reason· unspecific

    Can’t upgrade my iOS to accommodate app’s requirements.. App stop working and I can’t access think or swim anymore starting this past Monday. It was working fine last week. Terrible decision to discontinue previous version.

18. ★★★★★negative experience without a specific reason· unspecific

    Can’t use app until iOS is updated. No reason for this other than Schwab helping Crapple with their planned obsolescence.

19. ★★★★★negative experience without a specific reason· unspecific

    Is Schwab Controlled by Apple?. UPDATE: 6/3/2026 - Its bad enough if app stops working when Market is ready to dump. It is Diabolical to REQUIRE COMPLETE PHONE UPGRADES for app to work when MARKET IS TOPPING TOWARD HUGE CORRECTION. I can’t open my Think Or Swim App today. Apple Owned Schwab Owned Think or Swim is trying to force me to upgrade my phone that works fine for me otherwise.

20. ★★★★★negative experience without a specific reason· unspecific

    There is not enough data. There is not enough data to assume putting your financial future into ai pushed on the consumers app. The updates force the consumer to update to ai. Then ai has one bad day and destroys your portfolio future or life. It also means consumers need to find another source of data outside of Schwab to confirm that ai isn’t used to implement something like dynamic pricing. With metrics used to differentiate one’s worth by ai interaction like ai has done to its own developers.

21. ★★★★★negative experience without a specific reason· unspecific

    ONE STAR - NO LONGER supported - DELETE !. ONE STAR - because what HAS BEEN a great app all these years NO LONGER supported on less than IOS 18. So because of your developer shenanigans - we all LOOSE! Good bye!

22. ★★★★★negative experience without a specific reason· unspecific

    APPLE WHERE IS THE UPDATE. They ask to update to use the freaking app, then when you log into the store there is no freaking update button to push anywhere on the app. Apple is wasting my time back to my HP computer where I can trade in peace

23. ★★★★★negative experience without a specific reason· unspecific

    Doesn't work on older iPhones. My phone is incompatible with the latest iOS and therefore I can no longer access my account or trade on my mobile. Wish they had kept the older versions alive instead of blocking out everyone on older phones. The lack of foresight has been appalling. FYI Tastytrade and Webull work fine for me and they don't even require the latest iOS.

24. ★★★★★negative experience without a specific reason· unspecific

    Can’t upgrade, new software won’t download. I tried downloading the new TOS software but it appears there currently is no version for legacy iPhones limited to iOS 16. Given the number of devices out there still running it, there should be some acknowledgement and accommodation of these devices if only allowing the older software to function as-is rather than deactivating it as is happening now. (Other companies have made such accommodations. It would be nice if Schwab participated as well.)

25. ★★★★★negative experience without a specific reason· unspecific

    ThinkOrSwim no longer usable with last update. With latest update I cannot run the iOS app anymore. Great idea chopping off usage entirely for those unable to update to iOS 18.0 👏

26. ★★★★★negative experience without a specific reason· unspecific

    La app tiene dile ay últimamente. Últimamente la app presenta problemas de delay, para los que operamos opciones ODT esto es fatal. Me ha hecho perder unas cuantas operaciones últimamente ya que no reacciona ni llegan las órdenes en tiempo real, la app se bloquea cargando mucho tiempo, cuando llega ya pasó la oportunidad del trade.

27. ★★★★★slow performance and long loading times

    Bad app. ⭐ 1/5 — App crashed while I had open positions. Lost 283%. I had two active orders open when thinkorswim completely broke down. This wasn't lag — it was a total system failure: I could not close positions, could not modify stops, could not do anything. I watched my account get destroyed in real time with zero ability to intervene. 📉 Loss: −283% directly caused by a platform technical failure. Not a bad trade. A bug. SPECIFIC FAILURES: • App became completely unresponsive with live open positions • Close order button had zero effect — clicks did nothing • Unable to modify stops or limit prices during the outage • No prior warning of any maintenance or service degradation • No real-time support available during the emergency A trading platform has ONE non-negotiable job: order execution must work at all times, especially under market pressure. thinkorswim failed at exactly the moment it mattered most. This is not a minor inconvenience. This is a failure that wipes out real accounts. I am formally demanding: a full incident investigation, compensation for losses caused by the bug, and a clear user-protection protocol for system outages. DO NOT use this platform with real money.

28. ★★★★★negative experience without a specific reason· unspecific

    The absolute worst platform. This is literally the absolute worst trading platform I’ve ever used in my entire life. If you enjoy your order is freezing and then getting the worst possible price out of your position. And when you try to call the company and when you try to ask them in the chat, they don’t respond for literally hours sometimes. If you love all of this, then you will love this platform. They will take your money. They will take your fees and they will give you nothing in return

29. ★★★★★negative experience without a specific reason· unspecific

    App is stuck. App is saying I have yo update to the latest version of the app. THIS IS THE LATEST VERSION … markets open on a few hours. Great Smdh

30. ★★★★★crashes, freezes and errors

    Locked out of TOS mobile on all Apple devices. iPad M4, iPad, and two iPhones. Error message to update, but there are no updates available. Been a TOS advanced user for well over a decade. Forcing people to update to an iOS that has a 73% customer DISAPPROVAL rating is a great way to lose accounts.
