Show a recent purchase beside the product it refers to, or display a low-stock notice only once quantity drops below the chosen threshold. Fomo measures how shoppers interact with these messages.
- Who is this app for?
- Stores that want visitors to see recent purchases, stock levels or activity on the product page.
- Main advantage
- Shopify can supply individual purchases, product-level stock and recent purchase totals for different messages.
- Main limitation
- A notification needs an eligible event. A quiet store can have a working installation and still fall below its minimum visitor threshold.
Pricing and plans
Starter costs $25 for 8,000 monthly notifications. Estimate how many messages a visitor can see during one session. One busy product page can generate several impressions per visit. Several notifications in one browsing session can each use part of the allowance.
These are the monthly USD plans listed for the Shopify app. Capacity counts notifications shown. Business is the first listed plan with unlimited websites.
| Plan | Price & limits | What changes |
|---|---|---|
| Free | Free1,000 monthly notifications | Use sales and review notifications on one site. |
| StarterPapa pick | $25.00/mo8,000 monthly notifications | Increase monthly notification capacity. |
| Business | $75.00/mo40,000 monthly notifications | Add unlimited websites, inline product-page notices and segmentation tools. |
| Pro | $149.00/mo100,000 monthly notifications | Increase capacity to 100,000 notifications. |
Features and plan access
The Shopify connection can group variants and summarize purchases across a period. Inventory notices use a threshold. Cart-addition events have their own switch and supply product information for an abandoned-cart message.
An add-to-cart test produced a captured event with the product name and link. The dashboard reports impressions, clicks, pauses on hover, attributed transactions and monetary value separately. A hover pauses the animation. Only an attributed transaction contributes to the transaction count.

Formats & content
Show an active-visitor count as a standalone informational notification. An active-visitor notice can display a count without asking for contact information. Purchases and low inventory use separate templates. Match the format to the message: a persistent notice, an edge-of-page promotion and a central popup occupy different amounts of attention. Display conditions and billing limits still matter when a campaign contains no signup form.

Forms
Fomo has no confirmed capabilities in this section in the current review. The useful distinction is between collecting a contact and qualifying it: extra questions, consent and the next step after submission shape the signup flow. Phone-number collection and permission to send marketing messages are separate requirements.

|---|---|
| Total | 0 / 1414 unearned points — Email capture (1) · SMS capture (1) · Phone field (1) |
Surveys
Fomo has no confirmed capabilities in this section in the current review. Choose the response format around the question you want to answer. A recommendation score, a satisfaction rating and a quiz outcome serve different purposes; support for one does not imply the others or an automatic report.

Gamification
Fomo has no confirmed capabilities in this section in the current review. The game is the way an offer is revealed; prize configuration and the signup flow determine what the visitor actually receives. Compare the available formats, reward controls and repeat-play rules before choosing a mechanic for a promotion.

Targeting
Fomo’s audience and display controls include page targeting, geo targeting, and frequency cap. Cap notifications per visitor session and limit the age of eligible events. Apply rules based on the path of the current page. Audience conditions decide who qualifies, while triggers decide when a message opens. Frequency and scheduling controls serve a different purpose: keeping campaigns relevant across repeat visits and preventing the same promotion from appearing too often.

Experiments
Fomo has no confirmed capabilities in this section in the current review. Popup testing, email testing and automation experiments are separate capabilities. A useful comparison also considers traffic allocation, how a winner is selected and whether a no-popup control is available to measure the effect of showing a campaign at all.

Email & SMS
Fomo’s messaging channels include web push. Set up a browser push opt-in and view push reporting separately. Capturing an address in a popup and sending a marketing campaign are separate jobs. Compare native sending channels, automation and their allowances independently from the popup subscription; an integration with a mailing platform does not include that platform’s sending service.

Team & sites
Business and Pro include unlimited websites. The account owner can invite teammates by email. Check which teammates can change site-wide templates before giving a client access. Separate access to the account from permission to change or publish campaigns. For a team managing several sites, the useful questions are which sites each person can work on, who controls billing and whether each site needs its own subscription.

Developer
Fomo’s developer interfaces include HTTP API and browser API. Create and retrieve events, and create or update the templates used to display them. Reinitialize Fomo after a route change in a single-page application. The scope of each interface matters more than the API label. Opening an existing popup, sending a submitted form to an endpoint and creating or publishing campaigns are different operations. Agent access depends on those operations and the permissions exposed.

Support
Fomo has in-app support and a knowledge base covering Shopify settings, display problems and the API. Consider the support channel alongside the work you expect help with. Access to chat does not by itself promise round-the-clock coverage, a response deadline or someone to build your campaigns. Those service commitments need to be distinguished from ordinary product assistance.

|---|---|
| Total | 0 / 22 unearned points — Chat support (2) |
Editor & workflow
Fomo has no confirmed capabilities in this section in the current review. Editing, saving a draft and activating a campaign are separate stages of the workflow. Consider how changes are prepared and reviewed before visitors see them. An AI writing assistant also has a narrower role than an assistant that can change layout or targeting.

Data & reporting
Fomo’s data and reporting tools include revenue goals. View attributed transactions and their value separately from clicks. Use the reporting workflow to connect captured responses with the decisions you need to make. Downloading leads, scheduling reports and attributing revenue are different capabilities; a contact export alone does not establish an analytics dashboard or revenue measurement.

Integrations
Fomo can turn events from another service into notifications. For Mailchimp, select the lists to import subscribers from, then edit the fields displayed in the subscriber template.
Reviews, subscriber events and Shopify purchases can share a theme while keeping their own wording and eligibility rules. Our integration guide explains the connection types and workflows. For store-specific features, see our Shopify popup apps overview.

Works with Shopify
Fomo’s Shopify coverage includes storefront installation, native app, products and variants, and events and triggers. Display a product title and quantity below the chosen inventory threshold; variant grouping is configurable. After enabling cart events, adding an item on the Shopify storefront created a captured event with the matching product link. Installation, customer data, discounts and cart actions are separate capabilities. A Shopify listing alone does not establish support for all of them, and features supplied by a separate app need to be considered with that app’s access and pricing.

Capability score
The capability score brings together the confirmed features in the sections above, excluding pricing. Each metric belongs to one section, and a feature’s score includes its subfeatures. The breakdown shows how much each area contributes and where points remain unearned. It measures feature coverage, rather than conversion performance or value for money.

AI agent readiness
Agent readiness looks at a complete working process: understanding a campaign, creating or changing it, operating it, reading results and controlling access. This assessment adds context to the Developer section without awarding extra points. In-editor AI assistance and an external agent’s ability to operate the account are considered separately.
Event and template management API
An external application can create notification events and maintain templates. A store can send business events into Fomo through an inbound webhook.
| Agent task | What the agent can do |
|---|---|
| Create notification templatesSupported | The API supports creating and updating event types. |
| Read or post eventsSupported | Send event parameters with a template identifier, or retrieve events. |
| Generate designs with native AIUnconfirmed | The vendor describes AI timing insights. A prompt-based editor is unconfirmed. |
A vendor-operated MCP server is unconfirmed. The API requires authorized access to a Fomo application. No credentials are needed to read its reference.
What one view, action or submission could cost
A view is a visible widget display. An action is a target-link visit, coupon copy, add-to-cart or standalone consent. A submission sends form data, such as an email, phone number, enquiry or feedback. Submitting a form is not also counted as an action. These estimates do not establish that a plan supports every outcome.
At $25.00 per month, the selected plan allocates $0.025 per display, $0.50 per action and $1.25 per submission across 1,000 displays. The table rounds to cents. The 5% action and 2% submission rates are alternative assumptions, not measured performance or a vendor charge per event.
The capacity check assumes one site and 1,000 actual widget displays. Billing is based on monthly notifications, which is distinct from the actual outcomes used here. For form-free announcements, compare views or actions rather than submissions. Taxes, separately billed services and customer discounts are excluded.
| Outcome | Calculation | Estimated cost |
|---|---|---|
| One display | $25.00 ÷ 1,000 | $0.03 |
| 1,000 displays | $25.00 ÷ 1,000 × 1,000 | $25.00 |
| One action | $25.00 ÷ 50 | $0.50 |
| One submission | $25.00 ÷ 20 | $1.25 |
Fomo alternatives: which should you choose?
Stores that want visitors to see recent purchases, stock levels or activity on the product page. A notification needs an eligible event. A quiet store can have a working installation and still fall below its minimum visitor threshold.
Compare Promolayer and Hello Bar and Wisepops against that requirement. The cards below explain where each is a better fit. Match the billing unit, required features and site or account limits before comparing headline prices; the cheapest subscription does not always cover the same work.

Fomo vs Hello Bar
Compare Fomo and Hello Bar for low-stock notices, scheduled announcements, signup forms, quiet stores and view allowances.

About this review
We inspected the Shopify connection, active notification templates, page rules, the live event feed and dashboard counters. API operations were checked against Fomo’s developer reference. Dates beside sources indicate when the corresponding evidence was checked; publication does not imply that every source was rechecked that day.
“Documented” means the provider describes the capability. A named plan is shown only where we recorded tier evidence. “Not confirmed” means the evidence is insufficient, not that the feature is absent. Paid add-ons and higher-tier restrictions are stated separately. Conflicting billing information prevents a unit-cost estimate.
Recommendations are editorial judgments about fit and cost. Sources are linked next to the claims they support, and every calculation uses the assumptions above.
