Comparison

TikTok vs Meta for app installs

Two of the highest-volume paid channels for app marketers. Different creative grammars, different audiences, different cost curves. Here's how to choose between them - or run both.

Meta (Facebook + Instagram) Ads is the most reliable paid channel for app installs across categories - it has the best targeting, the most mature attribution and the broadest audience reach. TikTok Ads can deliver lower cost-per-install for the right categories (consumer apps, Gen Z and millennial-targeted, visual-led), but cost to acquire a subscriber or in-app purchaser is often higher, so optimising for in-app conversions matters more than headline CPI alone. Most successful app teams run both.

The detailed comparison

TikTok Ads vs Meta Ads (Facebook + Instagram), attribute by attribute.

Attribute	TikTok Ads	Meta Ads (Facebook + Instagram)
Best for audience age	13–34 (Gen Z, younger millennials)	All ages (broadest in mobile)
Targeting depth	Limited (interest, demo, lookalike)	Industry-leading (interests, custom audiences, lookalikes, retargeting)
Creative format	Vertical short-form video only	Image, video, carousel, Reels, Stories, Collection
Creative production demands	High (constant fresh native-feeling video)	Medium (a few well-produced ads can run for weeks)
Cost-per-install (consumer)	Often 30–60% lower for the right categories	Stable, predictable, but typically higher
Cost-per-subscriber / in-app purchaser	Often higher - more installs needed for the same paying users	Typically stronger install-to-purchase rates
Cost-per-install (B2B/enterprise)	High; rarely cost-effective	Workable with right targeting
Attribution clarity	Improving but still less mature	Mature (Meta SAN, conversion API, AppsFlyer/Adjust full support)
Algorithmic learning speed	Fast - TikTok's recommendation engine is the channel	Mature - Advantage+ campaigns optimise quickly given enough volume
Long-term defensibility	Creative compounds; viral hits can run for months	Reliable as long as audiences are unsaturated and creative refreshes

When to choose TikTok Ads

Native short-form video at scale across a younger audience.

Consumer apps targeting Gen Z and millennials.
Visually-led products (lifestyle, fitness, finance, food, dating, gaming).
Brands willing to invest in continuous creative production.
When you want to capture organic + paid upside through Spark Ads.

When to choose Meta Ads (Facebook + Instagram)

The most established paid channel with the broadest reach and targeting.

Almost any consumer app - Meta is the default high-volume channel.
B2B and SaaS apps targeting working-age decision-makers.
Apps in less-visual categories (utilities, productivity, finance).
When you need stable, predictable install volume to model unit economics.

Most App Media engagements run both channels in parallel: Meta as the always-on workhorse for predictable install volume, TikTok as the asymmetric upside lever for consumer apps with the right audience.

Our recommendation

Default to Meta first - it works for almost every category, has the best targeting, and scales predictably. Layer in TikTok if you're a consumer app targeting under-35s and have the budget to commit to continuous creative production.

Frequently asked questions

Is TikTok cheaper than Meta for app installs?

Often, yes on cost per install (CPI) - for the right categories (consumer, visual-led, under-35 audience), TikTok CPI can be 30–60% lower than Meta. But lower CPI is not the full picture: cost to acquire a subscriber or in-app purchaser is often higher on TikTok, because it can take more installs to reach the same number of paying users you would get from Meta. That is why optimising for in-app conversions (trial starts, subscriptions, purchases) matters more than headline CPI alone. For B2B, enterprise, or older audiences, Meta is typically the better channel regardless.

Can you scale spend on TikTok the way you can on Meta?

TikTok scales well up to a point, but creative fatigue happens faster than on Meta - you need to refresh creative continuously to maintain CPI. Meta typically scales further on a single creative.

Should I start with TikTok or Meta?

If you're a consumer app targeting under-35s, you can start with either. If you're any other category, start with Meta - it works across audiences and categories more reliably. Add TikTok once you've proven unit economics on Meta.

What about Apple Search Ads vs TikTok and Meta?

Apple Search Ads is a complementary channel, not an alternative. ASA captures users actively searching the App Store; TikTok and Meta capture users in feed. Run all three at meaningful budget levels.

How much creative do I need for each?

For TikTok: minimum 3–5 fresh creatives per week. For Meta: 3–5 fresh creatives per fortnight typically holds CPI. Less creative volume on either platform means faster fatigue and rising CPI.
