Evidence
The campaign, day by day
Grey bars are the installs you got each day. The line is what the model expects without the posts; the green area is the lift it credits to them.
- Installs per day
- Expected without posts
- Estimated lift from posts
- Posts went live
About 59 a day before the first post and 160 a day while posts were going live. The posts explain about 54% of the installs in that period.

Every creator
Sorted by estimated paying users. Code-confirmed counts are exact but incomplete: most viewers never type a code. Revenue so far is what their paying users have paid to date, after refunds; return on spend is that revenue divided by their payout.

Results by market
Extra conversions in each country during the campaign, compared with the weeks before it. Small markets borrow strength from similar ones, so their numbers don't jump around with every sign-up. Counts are installs.
49% of the extra conversions came from สหรัฐอเมริกา.
All markets: 1,921 extra installs (likely 1,793 to 2,040).

Notes on the data
62 posts have views that look low quality (see the post table). Their creators' estimates already reflect it.
Sales without posts follow your customers' local time and public holidays in สหรัฐอเมริกา อินเดีย สหราชอาณาจักร ออสเตรเลีย บราซิล แคนาดา และเยอรมนี.
Accuracy check against the simulation's truth
This report was produced from simulated data with known answers. The true number of post-driven installs was 1,947; the estimate was 1,888 (likely 1,654 to 2,119). 92% of creator ranges contain the true value (the target is about 80%).
Method
How these numbers were made
Method, ranges and decision rules
These numbers come from statistical models WhichPost built and trained in-house, fitted to Studybuddy AI (simulated)'s own data.
Every hour's installs are split into what the product would have had anyway and what each creator's new views added.
Paying users are installs multiplied by 10.1%. Share of installs that paid within 30 days (users old enough to have had the chance). Revenue per paying user so far: US$49.99.
Revenue so far is what paying users have paid up to 12 ก.ย. 2026, after refunds. The 383 customers who started paying since the first post have paid about US$49.99 each so far (likely US$49.99 to US$49.99); a creator's revenue is their paying users times that, so it assumes their customers pay like other new customers. Revenue per 1,000 views and return on spend divide it by their views and payout.
Ranges are 80% ranges, designed to contain the true value about 80 times in 100. Individual posts are rarely measurable on their own; post numbers marked “With creator” are the creator's estimate shared out by each post's views.
Decisions: rebook when even the cautious cost per paying user beats the target; pause when even the hopeful one misses it; test again when the range straddles it. No target was set, so the target is break-even: the revenue a paying user has brought so far (US$49.99).
