Shopify's App Store has over 8,000 apps. Eight. Thousand. You don't need most of them. Some can actively make your store slower and worse. In recent years, doing audits, I've often seen shops struggling with 30-40 installed apps — half of which run unused in the background and destroy your load time.
This list isn't a roundup of „the best apps" in the style of those annoying listicles every SEO blog publishes. It's my honest, battle-tested list of apps we actually recommend for most Shopify stores we work with — and why. Plus a few I actively warn against.
First, a word on apps in general
Before we get specific: apps aren't a substitute for good strategy. I've seen shops install five different conversion optimization apps — and still sit under 1% conversion. An app doesn't solve a structural problem. If your product photos are bad, no pop-up will help. If your checkout is three steps too long, no trust badge will save you.
Also: every app is a potential performance killer. In an audit last month, we found one app alone adding 2.3 seconds to product page load time. One. App. 2.3 seconds.
Rule of thumb: before installing a new app, check whether the problem can be solved with theme adjustments or Shopify's native features. 60% of the time, it can.
The apps we actually recommend
Email & SMS: Klaviyo
I covered this in detail in a separate article. In short: for shops over $250K in revenue, almost always the right choice. For smaller shops, Mailchimp or Omnisend is enough.
Cost: Free up to 250 contacts, realistically $150/month and up
Reviews: Judge.me or Loox
Two options, both solid. Judge.me is cheaper and works for most. Loox is more visual, with photo-based reviews — great for fashion, beauty, furniture.
Important: reviews are one of the strongest conversion levers, period. With one fashion client, we increased conversion by 18% through clean review integration. With furniture, it was 24%. If you don't have a review app yet, it's often the first lever I recommend.
Cost: Judge.me from $15/month, Loox from $35/month
SEO: Smart SEO or SEO Manager
Shopify's native SEO features are okay, but not great. Smart SEO or SEO Manager help with meta tags, schema, alt text, and broken link tracking. We mostly use Smart SEO — cheap and solid.
Caveat: no SEO app turns a bad page into a good one. These apps are helpers, not magic.
Cost: $10-30/month
Bundles & Cross-Sell: Shopify Bundles or Rebuy
Shopify's own Bundles feature has been very good since 2023 and is sufficient for most shops. If you need deeper personalization — „customers who bought X often also buy Y, sorted by likelihood" — go with Rebuy.
Rebuy is one of the few tools that actually justifies its price. With one beauty client, we increased average order value by 23% just through properly configured smart cart recommendations.
Cost: Bundles free, Rebuy from $99/month
Subscription: Recharge or Bold Subscriptions
If you offer subscription models — beauty boxes, food, coffee, whatever — Recharge is the standard. Has been running stably for years. Bold Subscriptions is the cheaper alternative with somewhat fewer features.
If you don't have a subscription use case: don't install. Period.
Cost: Recharge $99/month plus transaction fees, Bold from $49/month
Local taxes & invoices (EU/UK): Sufio
If you sell in Europe (especially DACH), you need Sufio or similar for proper invoicing. Shopify's built-in invoice function isn't sufficient for VAT-compliant invoices, country-specific requirements, or proper PDF formatting.
Sufio has been proven for years, runs stably, integrates with major accounting software. If you have any kind of serious accounting requirements, this isn't optional.
Cost: From $19/month
Currency & Markets: Shopify Markets (not an app)
We have an entire article on Shopify Markets. Short version: no extra app needed, Markets is integrated into Shopify. If you need international currencies, activate Markets.
Wishlist: Wishlist Plus
If your customers want to save products — typical for fashion, jewelry, furniture — you need a wishlist app. Wishlist Plus is solid. But: only install it if you'll actually use the feature. Otherwise you're just adding performance load.
Cost: From $14.99/month
Live Chat: Tidio, Crisp, or Gorgias
Three options, depending on use case:
- Tidio: cheap, simple, AI bot integrated. Good for small shops.
- Crisp: powerful tool, nice UI, versatile. Mid-market.
- Gorgias: helpdesk + live chat, integrated with Shopify customer data. Best choice for larger shops with real customer service volume.
If you have fewer than 50 customer inquiries per week, a simple contact form is enough. Live chat only pays off above a certain size.
Cost: Tidio from $29/month, Crisp from €25/month, Gorgias from $50/month
Pop-ups & Lead Capture: Klaviyo (Forms) or Privy
If you already have Klaviyo, use their built-in Forms — no extra tool needed. Otherwise, Privy is cheap and solid.
Important: pop-ups are a tool, not a marketing plan. A well-placed exit-intent pop-up on a product page can bring 2-3% more conversions. Poorly executed pop-up spam actually reduces your conversion.
Analytics in addition to GA4: Lucky Orange or Hotjar
Heatmaps and session recordings are invaluable for conversion optimization. You actually see where users drop off, what they click, where they get confused. Lucky Orange or Hotjar — both good. Lucky Orange is cheaper.
We often install this for three months, gather data, optimize — and then remove it because it costs performance. Running it permanently is rarely necessary.
Cost: Lucky Orange from $19/month, Hotjar from €32/month
Apps I actively warn against
Yotpo Loyalty (unless you're over $1M revenue)
Yotpo Loyalty is heavy, expensive, and usually overkill. Loyalty programs typically only work above a certain customer base and repurchase rate. With shops under $1M revenue, I have yet to see a loyalty app that paid for itself. If you absolutely need loyalty, look at Smile.io — leaner and cheaper.
Page builders like GemPages, Shogun
These tools promise „build your page with drag & drop." In practice: heavy, poor performance, expensive. If you need a custom page, have it built cleanly in the theme. Page builders often degrade Pagespeed by 30-50%.
Trust badge apps
Those little „100% secure," „SSL certified" badges. Studies show they actually reduce conversion because they draw attention to security concerns users didn't have before. Skip them.
SEO Booster, SEO Genius, SEO Optimizer (not Smart SEO)
There are dozens of SEO apps with dramatic names. Most are glorified auto-generators for meta tags. They don't do real SEO. Invest the money in actual content or SEO consulting instead.
Sticky add-to-cart apps
Bring 0.5-1% more mobile conversion, cost $15-30/month plus performance. Rarely worth it. Have it implemented in your theme — costs a one-time $200-500 and runs better.
How many apps is too many?
Rule of thumb: less is more. We recommend our clients stay under 15 active apps. More than that is usually a sign of strategic drift or poor architectural decisions.
In audits I always go through installed apps and ask three questions per app:
- Are we actively using this app?
- Does it bring measurable revenue or efficiency?
- Could the problem be solved natively in the theme?
If the answers aren't clearly in favor of the app: uninstall. In one of our recent audits, we removed 17 of 32 apps — Pagespeed score jumped from 41 to 67, with no functionality lost.
Watch the hidden costs
Apps often have hidden costs:
- Scaling: Klaviyo costs $100 at 5,000 contacts, $700 at 50,000. Is anyone planning that?
- Transaction fees: Recharge takes 1% per subscription transaction. At $100K subscription revenue, that's $1,000 extra per month.
- Setup costs: Complex apps like Klaviyo or Rebuy need proper setup, often $1,500-5,000 for an agency.
- Performance costs: Every additional app = more load time = less conversion. Hard to quantify, but real.
For every app, calculate: what does it really cost, what does it really bring?
My typical setup for a $500K Shopify shop
If I were building a shop today from scratch, with about $500K annual revenue, my stack would look like this:
- Klaviyo (Email + Forms)
- Judge.me or Loox (Reviews)
- Sufio (Invoicing for EU)
- Smart SEO (small SEO helpers)
- Shopify Bundles or Rebuy (Cross-sell)
- Tidio or Crisp (Live chat, optional)
- Lucky Orange (temporary for CRO phases)
That's it. Seven apps. Maybe eight if you have Markets active (which technically isn't an app). This configuration covers 90% of needs and keeps performance high.
Common questions
Should I audit my apps regularly?
Yes. At least twice a year. Apps creep in. Someone installs „something quick to test," and three years later it's still running in the background.
What do my apps really cost?
Look at your Shopify invoice. In many of our audits, we find $200-500/month in app costs that nobody actively uses anymore.
Can I switch apps without losing data?
For reviews: yes, with migration. For email: usually, with effort. For subscription apps: difficult — migrating existing subscriptions is risky. Generally: only switch when the added value is clear.
What about free apps?
Be careful. „Free" often means the app makes money another way — selling data, affiliate links, eventually pushing premium upgrades. Read the terms carefully.
My closing advice
Apps are amplifiers. They make a good shop better and don't make a bad shop less bad — they often make it worse, because performance suffers. Before installing the next app, ask: what specific problem does it solve? Do I really have this problem? Can I solve it differently?
If you'd like an app audit for your Shopify shop — we go through your installed apps, check performance impact, identify duplicate functions, and suggest optimizations. Often we cut $100-300 in monthly costs and lift Pagespeed by 20-30 points. Get in touch.
