All three read real data, which is worth saying before anything else — the low stock counter shows inventory levels and the visitors counter reads unique visitors, live traffic and product views.
Shopify merchants who genuinely run low stock or timed promotions and want to surface that on the product page — the low stock counter is tied to real inventory, which makes it the honest one of the three when your stock actually is low.
your stock is not low and your sale does not end, because a claim a shopper would read as false is one the FTC treats as deceptive; or your brand sells on trust, where a blinking counter costs more in credibility than it returns.

These are three separate apps from one developer, each installed and billed on its own. The Visitors Counter is $1.99 a month or $16.71 a year, with a genuine free plan that carries the counter itself, customisation, product-level targeting and holiday presets — the $1.99 adds an upsell banner for your most-viewed product, on a 3-day trial. The Countdown Timer listing shows a free tier and no paid ladder.
Check your platform and version specifically. Shopify support is close to universal in this category, while WooCommerce, BigCommerce, Magento and headless setups vary a lot, and 'supported' sometimes means a generic API rather than a maintained app. A listing in your own platform's app store, with recent reviews there, is a better signal than the vendor's logo wall.
