The Shopify App Store has thousands of apps, and it's easy to install a dozen in your first week, watch your monthly bill climb, and slow your store down in the process. The truth is that most successful small stores run well on a handful of apps that cover the essentials. This is a practical, honest list of the categories that actually matter — and a reminder that fewer, better apps usually beat a long list.
We won't crown one "best" app in each category, because the right pick depends on your store — but we'll show you what to look for and where apps earn their keep.
Every app you add is a monthly fee and a little more weight on your store. Install the few that clearly pay for themselves — and skip the rest.
The categories that earn their keep
A few app types reliably pay for themselves for small stores: email marketing (Klaviyo, Omnisend) to turn one-time buyers into repeat customers; reviews (Judge.me, Loox) to build trust with social proof; and upsells and cross-sells to lift average order value. These three touch revenue directly, which is why they're worth their monthly cost when your store has real traffic.
Helpful, situational apps
- Support: a live chat or helpdesk app if you get frequent customer questions.
- Loyalty: a points or referral app if repeat purchases are central to your model.
- Subscriptions: a recurring-order app if you sell consumables.
- SEO helpers: a lightweight SEO app for meta data and image optimization — useful, but don't overdo it.
Apps you can usually skip early on
In the early days, resist analytics dashboards you won't read, pop-up apps that annoy more than they convert, and anything that duplicates what Shopify already does natively. Every extra app adds cost and can slow your store — which, as we cover in our guide to store speed, directly affects sales. Add apps when a real need appears, not just because they exist.
How to choose well
Read recent reviews, check the app is actively maintained, and prefer ones with a free trial so you can test the impact. Watch your store speed before and after installing. And every few months, audit your apps and uninstall anything you're not actively using — it's the easiest way to cut cost and reclaim performance.
Frequently Asked Questions
What are the most important Shopify apps for a new store?
The apps that most reliably pay for themselves are email marketing, product reviews, and upsell tools, because they touch revenue directly. Beyond those, add support, loyalty, or subscription apps only if your store genuinely needs them. Start with a small, focused set rather than installing everything at once, and expand as real needs appear.
Do Shopify apps slow down your store?
They can. Each app often adds code that loads on your pages, so a long list of apps can noticeably slow your store, which hurts conversions and SEO. This is why fewer, well-chosen apps usually beat many. Check your store speed before and after installing, and remove any app you're not actively using.
How much do Shopify apps cost?
Many apps are free or freemium, but the useful paid ones commonly cost $10–$50 each per month, and a few premium tools cost more. Individually they seem small, but several together can quietly become one of your biggest running costs. Only keep apps that clearly earn back more than they cost.
Which Shopify app is best for email marketing?
Klaviyo and Omnisend are two of the most popular choices for small stores, both integrating tightly with Shopify for automated flows like welcome and abandoned-cart emails. The best one for you depends on your budget and how advanced you need the automation to be. Most offer free tiers, so test one before committing.
Do I need a reviews app on Shopify?
For most stores, yes — customer reviews are powerful social proof that lifts trust and conversions, and a reviews app like Judge.me or Loox makes collecting and displaying them easy. If you're a brand-new store with no orders yet, it can wait a little, but it's one of the first apps worth adding once sales begin.
How many apps should a Shopify store have?
There's no fixed number, but many successful small stores run well on around five to ten well-chosen apps. The goal is coverage of your real needs without unnecessary cost or speed loss. Audit your apps every few months and uninstall anything you're not using — it's the simplest way to control both your bill and your store's performance.
