One complaint, in dark mode on iPhone, charts first flash bright white display before presenting chart. Very irritating. 6/16/26 STILL VERY IRRITATING! ### 4/5 — Great Website, App with potential *2026-05-22* Es wäre gut, wenn noch mehr Optionen analog der Website eingefügt werden, um eine Aktie zu bewerten. Z. B. Price tangible Book Value, tangible book value, E.V./EBIT. ### 4/5 — Improvements *2026-05-20* Would be great if there was a preset report that showed sources of $ change by time period ### 4/5 — Falta performance *2025-08-23* As funções e dados são ótimos mas o app é muito lento – mesmo num iPhone recente – para baixar as cotações ao vivo depois de aberto. ### 4/5 — Useful app *2024-10-12* Nice to have the app. I was not able to find My Screens or My Watchlists :( ### 5/5 — Solid *2024-09-27* Great app with very few hiccups that I can think of. ### 5/5 — Fantastic Platform *2024-09-25* Koyfin is a fantastic set of tools for the price and the devs keep adding new features regularly. ### 5/5 — Fresh & Clean *2024-09-02* Love the clean, easy-to-use interface. It makes finding market data and analysis super easy. I also love how quick and straightforward everything is ### 5/5 — So helpful *2024-05-21, version 1.7.2* So helpful ### 5/5 — Amazing *2024-05-09* Superb app from an amazing company. Highly recommend from someone who has used Bloomberg, Capital IQ, etc professionally for many years. I use Koyfin for fundamental analysis and opportunity screening and it has been game-changing. ### 5/5 — Koyfin Mobile App *2024-05-02* Love Koyfin, continually improving and adding functionality! ## Most critical reviews (10 lowest-rated) ### 1/5 — Graphs *2026-08-07* I’m a paid Koyfin subscriber. Charts/graphs in the mobile app are displaying as blank. Other portions of the app are loading normally. I’ve restarted the app/device and the problem persists. Had to uninstall the app and reinstall to get graphs to work. Paying $109 monthly for something this buggy won’t happen much longer for me ### 1/5 — Timeout exceeded *2026-06-04, version 1.11.0* Timeout exceeded Not an app ### 1/5 — Useless *2026-01-31* Most features cost money. I have spent hours trying to upload my portfolio to it for it only to to work or crash. I don’t have enough time to enter each stock one by one and change it every time I make the smallest change. ### 1/5 — Crashes on Search *2025-10-16* Tried for a day to use the app but it crashed every time I tried to search for a stock. The search bar would pop up for half a second, then the screen goes completely black and doesn’t come back until you hard close and reopen the app. The app features seem very good (they have a pre-populated watchlist that I used to check out a couple stocks), but it isn’t a useful if I can’t search or add my own tickers to the watchlist… Edit: reduced from two stars to one due to them auto-subscribing you to the premium account then blocking you from deleting your account while you have an active subscription, which can’t be edited in the app. **Developer response:** We have released an updated version since your review that hopefully solved the issue you are experiencing. Please update and check again. If the issue is not resolved, please contact us at help@koyfin.com so we can provide further assistance. ### 1/5 — Stay away *2025-05-22, version 1.7.8* You will automatically enrolled in their Advisory Pro package. Cancelling is incredibly difficult. I suggest everyone steer clear. ### 1/5 — Unable to delete my free trial, hence my subscription *2024-08-30* The apps looks more of trap with unclear subscription plan, neither the option to delete it by your self. This is clearly is one time scam, I hope the Apple store management becomes aware of it **Developer response:** We offer a free one week trial when you first use our platform so you can experience all we have to offer. This is completely free and you will not be charged after the trial is over. If you have any concerns, please contact us at help@koyfin.com ### 1/5 — no portfolio view *2024-08-15, version 1.7.4* can’t view my own portfolio in the app. limited functionality compared to desktop web. kinda pointless ### 3/5 — Ux friendly *2025-12-22* Great ux/ui. This is the best “at a glance” foundation app imo. I do not broker through them and recommend fidelity’s app for that. They need to display deeper finance information/multiples/ratios, they have just barely the absolute minimum there. You will need additional tool/s to make informed investing decisions. Really a fantastic product overall and the best free app i have found. Let me know if there is something better out there! ### 3/5 — Subscribed to highest tier, not portfolio anything *2024-05-08* I thought this would be a good way to manage my portfolio. Buy the feature just doesn’t exist on the iPad app. Most of the other tools seem to be in TradingView, Unusual Whales, etc. **Developer response:** We're happy to let you know that you can now access My Portfolio from the mobile app. Please, update to the latest version to see the new feature. ### 3/5 — Mostly good *2024-04-03* Lots of useful data, much more than I have found on other sites. One complaint, in dark mode on iPhone, charts first flash white display before presenting chart. Very irritating. ## Most praised reviews (10 highest-rated) ### 5/5 — Nice app ever *2026-08-04* I love it ### 5/5 — Really useful platform for value investors *2026-06-30* 기업의 재무재표, 어닝콜과 컨콜 아카이브, 그리고 여러 니치한 기능들까지 매우 유용합니다. 미국시장에서 투자하는 분들에게 추천드립니다. coporate financial statements, earnings call&conference call archive, and various niche stuffs are highly useful. I recommend it especially to anyone investing in US market. ### 5/5 — best trace app *2026-06-21, version 1.11.0* the worldwide stock trace app ### 5/5 — Login bug? *2026-06-06* How can I sign in with gmail? Thats the user I have on web ### 5/5 — Must have!! *2026-05-22* The best affordable app for economic and financial information. Can’t work wiithout it!! ### 5/5 — very helpful *2026-04-11* thanks ### 5/5 — The best stock app out *2025-10-08* Powerful fundamental data covering all global stocks, charting, consensus estimates, portfolio monitoring, watchlists and top movers. ### 5/5 — Love Koyfin!!! *2024-12-05* The best hands down investor friendly app where I get all my news and stock updates from. ### 5/5 — The absolute best *2024-10-10, version 1.7.5* Charting at its best ### 5/5 — Going to put Bloomberg out of business *2024-10-08* Great app - accurate and functional - just needs better news - market release - company presentations and broker research - Highly Recommended --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
