The only thing we changed to increase sales — not the product, price, or competitors

A small test we ran recently made me rethink how much “market selection” matters for app growth.

The app was a fitness app.

The product did not change.
The price did not change.
The competitors did not change.
The content did not change either.

The only thing we changed was where the content was distributed.

The app had been trying to grow in the US, mostly by posting fitness-related content on Instagram. But the US fitness app space is brutally crowded. Everyone is posting. Everyone is running ads. Everyone is fighting for the same attention.

So we tested Japan.

Japan looked interesting because fitness content is growing there, and it is a high-value mobile market where users are already used to paying for apps and subscriptions.

But there was one problem.

Posting from the US and simply translating captions into Japanese does not mean Japanese users will actually see the content. Local posting signals still matter.

So instead of asking the founder to buy VPNs, eSIMs, burner phones, or set up a complicated posting environment, we posted the existing videos through a Japan-local Instagram account using a real device and SIM in Japan.

We also localized the Japanese subtitles, voice, captions, and hashtags.

No new videos.
No new creative team.
No new product.
No new pricing.

Just the same content, distributed from a different market.

After roughly two weeks, the app got 20 downloads from Japan.

That is not a viral success story.
It is not a huge number.
But it was the first clear signal from a market the app had basically never reached before.

The lesson was simple:

Sometimes growth does not come from changing the product.
Sometimes it comes from changing the market where the product is discovered.

One mistake I would avoid: spending weeks trying to hack location with VPNs, SIMs, and random technical setups.

Between setup time, account risk, and trial and error, it often costs more than people think.

For this test, using a local posting setup was much cheaper than building the whole environment from scratch.

I almost do not want more app founders testing Japan because the market still feels less crowded than the US for some categories.

But if your app is struggling in a saturated market, it might be worth asking:

Is the product bad, or is it just being discovered in the wrong place?
