The ecommerce mobile app filled up in India while the leak widened: two numbers that fell together

What AppsFlyer's India report says about the ecommerce mobile app#

The fox counts the trail as well as the quarry. A pack of paw prints tells you many animals came through, and only the track further on tells you how many stayed. That is the right instinct for AppsFlyer's State of eCommerce for Marketers in India, 2026 Edition, which trade outlets reported on 23 September, because the ecommerce mobile app it describes gained users quickly and kept fewer of them.

A caution first. The research behind this piece did not find an AppsFlyer-hosted page for the India edition, so every India figure here comes from trade outlets relaying AppsFlyer's press text. AppsFlyer's global companion report is the closest primary page, and it describes advertisers doubling down on existing users as paid installs decline. Read the India numbers as AppsFlyer's, relayed, until the report itself is checked.

The scale of the dataset is not small. Social Samosa reports the report covers 2.24 billion installs across 210 apps, $290 million in user acquisition and remarketing spend, and 1.63 billion Android remarketing conversions in India's shopping vertical. That is a wide field for one ecommerce mobile app vertical, though a vendor's own panel, and it measures apps that use AppsFlyer.

Two of those numbers come from Infashion Business and Marketing Mind: Android installs up 85 per cent over two years versus 2 per cent globally, and organic installs rising 143 per cent year on year during the Navratri quarter, versus 18 per cent globally. India also accounts for 63 per cent of Android shopping installs and 71 per cent of sessions among measured markets. For anyone running mobile app user acquisition in India, the market is enormous and still expanding.

Context from the stores explains the crowd. Mobilegamer reports that, per Google's CEE apps lead, Google Play submissions rose from 46,136 in March 2025 to 111,047 in July 2026, while App Store submissions grew from 46,889 to 117,648. More than twice as many apps are being submitted, which is a reason discovery costs more and holding a user of your ecommerce mobile app matters more.

The gap: Day 30 retention fell 41 per cent while remarketing spend fell 42#

Here is the finding about the ecommerce mobile app that made the headlines. MediaNews4U reports that Day 30 retention on Android fell 41 per cent between Q4 2025 and Q2 2026, after remaining broadly flat through the previous year. The same reports say remarketing spend fell 42 per cent while spend on acquisition rose about 10 per cent. Global Day 30 retention fell 30 per cent over the same window, so India's drop is steeper but not unique.

So one ecommerce mobile app category was buying more new users and fewer return visits, and retention slid. The pattern is easy to narrate: brands chased installs and stopped calling their customers back. It is also a narrative, and the fox distrusts a tidy story. Two lines moving together prove nothing about cause, because a Day 30 fall could just as easily come from a wave of festive discount-seekers who were never going to stay.

That question comes from one product manager at an early-stage Indian startup, so it is a voice and not a dataset. It is still the right question to put to any budget that leans on acquisition, and it is the question the retention gap invites.

The chart is derived, not reported: it takes the published percentage changes and indexes them to 100 so they can share a scale. The base period is worded slightly differently across outlets, from the last two quarters to Q4 2025 to Q2 2026, so treat the shape as illustrative of the relationship, not a precise reading. The honest summary is that two things fell together and one of them, app remarketing, is a lever a team controls.

• 85%

  growth in India's Android shopping installs over two years

• -41%

  Android Day 30 retention change, Q4 2025 to Q2 2026

• -42%

  reported fall in remarketing spend

• +10%

  reported rise in acquisition spend

• -30%

  fall in global Day 30 retention over the same window

One more caveat keeps the picture straight. Trade reports also note that Android fraud, though below global benchmarks, ticked up 30 per cent quarter on quarter after two years of steady improvement. Some installs that never come back are installs that were never real, which is another reason a Day 30 number can fall without any change in how customers behave.

Correlation is not cause: what the evidence on app remarketing says#

The academic evidence on retargeting an ecommerce mobile app is split, which is the strongest argument for testing. A field experiment reported in the Journal of Marketing Research found that dynamic retargeted ads were, on average, less effective than their generic equivalents, in a study of one travel firm. A later randomised study using ghost ads found that retargeting lifted website visits by 17.2 per cent and purchases by 10.5 per cent for one online retailer.

Both are single-company experiments, and both are abstracts here, so neither is a rule for an ecommerce mobile app in India. Together they say something useful. App retargeting can move purchases, and it can also fail, depending on the creative, the audience and how the effect is measured. Cutting it because it looks expensive, or scaling it because it looks busy, are both guesses until a holdout says otherwise.

The iOS audience is capped by consent#

On iOS the audience for mobile app remarketing is limited before any test begins. Apple's documentation says an app needs to use the App Tracking Transparency framework if it collects data about people and shares it with other companies to track them across apps and websites. Adjust reports that the global industry average for opt-in rates rose to 38 per cent in Q1 2026, from 35 per cent in Q1 2025.

That is a global average from one vendor, not an Indian one, and it applies only to the iOS slice of any audience. India's Android-heavy market leans on different signals, including deep links that verify the association between an app and a website. Android's documentation says App Links verify deep links to your own website by establishing a trusted association, and Apple's universal links rest on a file only you can store on your server.

Five fixes for an ecommerce mobile app team#

None of these ecommerce mobile app fixes needs a new tool. All of them can start this month, and all survive whatever the next vendor report says.

The fourth fix comes with a warning from the industry itself. AppsFlyer's India general manager Sanjay Trishal said, before the report, that if a customer only returns when there is a Rs 100 coupon, you have bought a transaction, not necessarily built a relationship. That is an executive's opinion, reported by a news service, and it is worth taking seriously because the incentive to buy returns is an incentive to discount.

The second fix is the one most teams skip, because a holdout feels like wasted budget. It is the opposite. For an ecommerce mobile app, a test that shows app remarketing lifts purchases justifies scaling it with confidence, and a test that shows no lift saves the spend. Either way the result is a number you can defend to finance, which a hunch is not.

How to read a vendor report before you budget on it#

An ecommerce mobile app team should treat a vendor report as a useful instrument and a poor oracle. It describes the customers of the vendor that wrote it, in the period the vendor chose, with a definition the vendor set. The fox reads it the way it reads a stranger's tracks: gratefully, and with a second look.

Now the questions to put to any such report. They apply to AppsFlyer's, and to every vendor's, and they are folkfox's own editorial checklist rather than anything the report states.

The fourth question is the sharpest. A market-wide fall in remarketing spend and a market-wide fall in retention could come from entirely different apps. Only a cohort-level view, which the vendor holds and the trade press does not, can show whether the apps that cut remarketing were the apps that lost users.

For a wider read on a tighter measurement picture, see folkfox's pieces on AppsFlyer and AI answer attribution and on why a retargeting pool is not always full of people. If you would rather have the retention view built than described, that is the work of folkfox app marketing, with paid social and PPC planned around holdouts, and content marketing that gives a returning user a reason to come back.

Set the baseline before you change a budget. Record Day 1, Day 7 and Day 30 retention by source for the last two quarters, alongside acquisition and remarketing spend, so any later move can be read against something real. The fox does not guess the depth of a stream, it puts a paw in first.

Expect the early signal in retention before revenue. A remarketing test that works shows up first as repeat sessions and only later as purchases, and a team that watches only the revenue line will read the result late. Measure the boring metrics first, because an ecommerce mobile app is won on the days after the install.
