Bugs

App constantly loses custom settings. Add custom columns to your watchlists and watch them disappear at random

It’s good

The app is great.

To share some feedback, so news/press releases for smaller Canadian companies don’t work. I’d love to see this corrected!

The ability to see quarterly financial data on mobile would be neat :)

Endless loop

App keeps promoting to update. When I hit update endless loop of prompting to update. When I uninstall and then install the same messages. Maddening

Graphs

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

Nice app ever

I love it

Really useful platform for value investors

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.

best trace app

the worldwide stock trace app

Mostly good

Lots of useful data, much more than I have found on other sites. One complaint, in dark mode on iPhone, charts first flash bright white display before presenting chart. Very irritating. 6/16/26 STILL VERY IRRITATING!

Login bug?

How can I sign in with gmail? Thats the user I have on web

Response from developer

Sorry for the late response. You probably noticed that we now have Social Login introduced in the app too. So you can use your Google Account to sign in now. If you need further assistance, please reach us at help@koyfin.com

Not an app

Great Website, App with potential

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.

Must have!!

The best affordable app for economic and financial information. Can’t work wiithout it!!

Improvements

Would be great if there was a preset report that showed sources of $ change by time period

very helpful

thanks

Useless

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.

Ux friendly

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!

Crashes on Search

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.

The best stock app out

Powerful fundamental data covering all global stocks, charting, consensus estimates, portfolio monitoring, watchlists and top movers.

Falta performance

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.

Stay away

You will automatically enrolled in their Advisory Pro package. Cancelling is incredibly difficult. I suggest everyone steer clear.
