The best stock alert apps in 2026
·7 min read
Key takeaways
- Alerts are near-universal, so pick on the details: trigger types offered, how many alerts the free tier allows, and whether the check runs server-side.
- Yahoo Finance is the strongest free general-purpose pick — widest coverage, alerts included, and no subscription needed to use it seriously.
- Stocktwits is the pick if you want the conversation around a move, not only the move.
- StockPlus is built for the alert-first user: price and percent-change alerts plus a daily AI briefing, free tier included, Pro at $2.99/month.
- Research-heavy tools like Seeking Alpha and Simply Wall St are priced for analysis, not alerting — buying them for alerts alone is overpaying.
Alerts are the most-claimed and least-differentiated feature in finance apps: nearly every product in this list has them. So the comparison that matters is not whether an app alerts you, it is what it can trigger on, how much the free tier allows, and whether the notification arrives when your phone is in your pocket.
What actually separates alert apps
- Trigger types. Absolute price alerts are universal. Percent-change alerts (“tell me if it moves 5% in a day”) are not, and they are what you want for positions where you have no target price. Some apps also trigger on new data — an insider filing, an earnings date — rather than on price.
- Free-tier limits. Alerting is usually free; the limit is on how many you can keep live at once. That number, not the headline feature list, is what you will run into.
- Where the check runs. Alerts evaluated on a server and delivered as push notifications work whether or not the app is open. Alerts evaluated on-device depend on background execution the OS is free to suspend.
- What arrives with it. A bare price notification leaves you to work out why. Some apps attach the news, the discussion, or a summary of the day around it.
StockPlus — built alert-first
AI stock tracker
Our appBoth trigger types — absolute price and percent change — with the check running server-side and delivery over push, so alerts do not depend on the app being open. Alerts are included on the free tier; Pro raises the number you can keep live at $2.99/month. What arrives alongside them is the differentiator: one two-minute AI briefing each morning, a real-time watchlist, and congressional and insider trade feeds, so a firing alert usually already has context attached.
Where it loses: coverage and research depth. For screening fundamentals or reading analysis, the tools further down this list are better.
See what StockPlus doesThe other six, and who each one suits
Free market data portal
Yahoo Finance
The default free finance portal — quotes, news, and portfolios for practically every listed company, with paid Premium tiers on top.
The strongest free general-purpose pick. Coverage is effectively total, alerts are included, and you never have to subscribe to use it seriously. The cost is attention: alerts arrive alongside an endless news feed, so nothing is summarised for you.

- Premium $7.95–$39.95/mo billed yearly, as of August 2026
Retail social sentiment network
Stocktwits
A social network for traders, where each ticker has a live message stream and a crowd-sourced bullish or bearish sentiment reading.
Pick this if the conversation around a move matters as much as the move. When an alert fires you land in a live message stream for that ticker — genuinely useful for understanding why something gapped, and genuinely noisy.

- Ad-free about $8/mo, Edge about $22.95/mo, as of August 2026
Portfolio tracking app
Delta
A mobile portfolio tracker, now owned by eToro, that syncs stocks and crypto from brokers, wallets, and exchanges into one balance.
Portfolio-first. If you hold crypto alongside stocks across several accounts, alerts sit next to one combined balance, which no stock-only app gives you. Less compelling if you simply want to be told a ticker moved.
- Alerts

- Free tier
- Yes — limited assets
- Paid from
- PRO tiers, roughly $54–$108/yr as of August 2026
Visual fundamental analysis
Simply Wall St
Fundamental analysis turned into pictures — the Snowflake visual summarises value, future, past, health, and dividend for a company at a glance.
Alerting is a notification on companies in your portfolio rather than a threshold engine. Bought for its visual fundamental analysis it is good value; bought for alerts alone it is the wrong tool.
- Alerts
- Notifications on portfolio companies
- Free tier
- Yes — limited stock views per month
- Paid from
- About $10/mo Premium and $20/mo Unlimited billed yearly, as of August 2026
Alternative data platform
Quiver Quantitative
An alternative-data platform that surfaces congressional trading, lobbying, government contracts, insider filings, and retail chatter as browsable datasets.
Alerts here fire on new data — congressional filings, insider transactions — rather than on price. That is a different and, for some people, more interesting trigger, but it does not replace a price alert.
- Alerts
- Alerts on new data and insights
- Free tier
- Yes — limited dataset access
- Paid from
- API from $30/mo, or $25/mo billed annually, as of August 2026; the web Premium price is behind a registration wall
Research and analysis subscription
Seeking Alpha
A research subscription built around contributor analysis, earnings call transcripts, and a quantitative rating for every stock.
Priced for research, not for alerting. If you already read the analysis, the alerts are a fine bonus. If you do not, this is the most expensive way in this list to learn that a stock moved.
- Alerts
- Yes
- Free tier
- Yes — limited article access
- Paid from
- Premium about $299/yr, as of August 2026
How to choose in one minute
- You want free and comprehensive: Yahoo Finance.
- You want alerts plus context, without a research subscription: StockPlus.
- You want to know what people are saying about the move: Stocktwits.
- You hold crypto and stocks across several accounts: Delta.
- You want alerts on filings rather than on price: Quiver Quantitative — and see how the congress stock trackers compare against reading the disclosures yourself.
- You read investment research anyway: Seeking Alpha or Simply Wall St, where alerting is a bonus rather than the reason to subscribe.
Whichever you pick, the setup matters more than the app — how to set stock price alerts you will actually act on covers choosing the trigger type and the threshold.
Frequently asked questions
What is the best free stock alert app?
For breadth, Yahoo Finance: it covers nearly every listed company, includes alerts, and is usable without paying. If you want a smaller, alert-first app that also summarises the day, StockPlus includes price and percent-change alerts in its free tier.
Do stock alert apps cost money?
Most offer alerts on a free tier and charge for depth — more live alerts, real-time rather than delayed data, or research features. Paid tiers in this comparison range from about $3 per month to roughly $299 per year, verified in August 2026 against each vendor's own pricing page.
Which app has percent-change alerts, not just price alerts?
Percent-change triggers are less common than absolute price triggers. StockPlus supports both. If a percent-change trigger matters to you, check it explicitly before subscribing — many apps describe both as simply 'alerts'.
Can I get stock alerts without a brokerage account?
Yes. Every app in this comparison is a tracking or research tool rather than a broker, so alerts work without linking a brokerage account and without funding anything.
Are stock alerts investment advice?
No. An alert reports that a threshold you chose was crossed. It carries no view on whether to buy or sell, and nothing in this comparison is investment advice.
