TikTok’s own meta-analysis with Adjust (North America, 2024) reports that TikTok drives 19% more assisted app installs, an 8% lower uninstall rate, and a 54% higher re-attribution rate than other major platforms — with cost-per-install running 40–65% lower in several app categories.
These are TikTok-published, self-reported figures, so read them as the platform’s best case rather than a neutral benchmark — but the direction is consistent with what app advertisers see in practice: TikTok is often the most cost-efficient install channel, with the catch that measurement and creative discipline determine whether those cheap installs actually convert downstream.

Does TikTok actually drive efficient app installs?
According to TikTok’s meta-analysis with the MMP Adjust (Jan–Dec 2024, North America), TikTok outperformed other major platforms on the metrics that matter for app growth:
| Metric (vs other major platforms) | TikTok advantage |
|---|---|
| Assisted app installs | +19% (US +15%, Canada +24%) |
| Re-attribution (re-engagement) rate | +54% (Canada +184%) |
| Uninstall rate | −8% (Canada −13%) |
| CPI — Health & Fitness | −65% |
| CPI — Publication | −57% |
| CPI — Entertainment | −50% |
| CPI — Education | −40% |
How much does a TikTok app install actually cost?
TikTok’s category figures above are relative (“lower than other platforms”), not absolute. For absolute numbers, independent industry benchmarks put TikTok app-install CPI roughly in the $0.70–$4.50 range depending on vertical — hyper-casual and entertainment apps at the low end, finance and mid-core gaming at the high end (per third-party aggregators such as Business of Apps).
Treat any single CPI number with caution: TikTok CPI swings widely by geo, season, and creative quality, and the platform’s own comparative numbers are drawn from North America only.
Do Spark Ads outperform standard in-feed ads?
Directionally, yes — and it’s one of the more consistent findings across independent analyses. Spark Ads (ads run through a real creator’s native post rather than a brand-built in-feed unit) tend to win on conversion rate and video completion because they carry the authenticity signal of organic content.
We won’t put a false-precision number on it; the practical takeaway is that routing spend through creator-native Spark Ads, rather than polished brand creative, is usually the higher-converting default on TikTok. Test it against your in-feed control and let your own conversion data set the split.
What does this mean for your TikTok strategy?
- Treat TikTok as an efficiency channel, but verify downstream. Cheap, high-volume installs only pay off if they convert to trials and revenue — instrument post-install events and compare Day-30 LTV cohorts against your Meta baseline before scaling.
- Lead with creator-native creative. Spark Ads and UGC-style content consistently outperform brand-polished in-feed units; build your TikTok creative to look native, not like a repurposed Meta ad.
- Lean into re-engagement. TikTok’s standout metric is re-attribution, which makes it a credible remarketing channel, not just an acquisition one.
- Don’t trust a single CPI number. Benchmark your own account by vertical and geo; published ranges are starting points, not targets.
