TikTok Spark Ads for Endel app installs: CPI $3 vs $7
Commentary byROASArchiveOur analysis, not theirsEndel used TikTok Spark Ads to drive app installs, and TikTok reports a cost per install of $3 against $7 with non-Spark ads.
That works out to less than half the cost per install.
The result comes from TikTok's own success story about its ad format.
- CPI: $3 against $7 with non-Spark ads, which works out to less than half the cost per install.
- No spend, install count, duration or market is shared, so the scale of the result is unknown.
- The $7 baseline is non-Spark ads, but TikTok gives no detail on how those ads or their audiences differed.
The change
Before
The comparison point is a $7 cost per install with non-Spark ads, the standard TikTok format.
After
Endel ran Spark Ads, the TikTok format that boosts organic posts from a real account, and got installs at $3 each.
Our reading: why it likely worked
Our interpretation, not the advertiser's claim.
- Spark Ads run from a real TikTok account, so they look like normal posts and people may scroll past them less.
- A calm, audio-led app like Endel may suit native-looking content better than a polished app-store style ad.
- The gap may partly reflect differences between the Spark and non-Spark campaigns beyond the format itself.
Caveats: This is TikTok publishing a result about its own ad format, so it is vendor-reported. It is a campaign result with no stated control, and spend, installs, dates and markets are not shared.
How to run this in your account
- Hypothesis
- If we run our best organic TikTok posts as Spark Ads, then cost per install will drop because native posts get more attention than standard ads.
- Primary metric
- CPI
- Guardrails
- Day-7 retention of installed users
- Trial or subscription start rate
- CTR
- Who should try it
- App advertisers who already post on TikTok and have organic videos that do well. It probably won't help if you have no organic content worth boosting.
