Key takeaways
- ChatGPT tops the annual chart. By full-year 2025 global installs (Apptweak), OpenAI's assistant drew an estimated 845 million-plus downloads, overtaking Instagram and TikTok for the first time.
- Sources disagree on #1. Sensor Tower's full-year data instead put TikTok first and ChatGPT second — so treat the top spot as a close, methodology-dependent call.
- AI reached the very top for the first time, with ChatGPT ahead of, or neck-and-neck with, the biggest social networks.
- CapCut is the standout non-social entry, riding the short-form video boom as the editor behind millions of TikTok and Reels clips.
- Every figure here is an estimate. Apple and Google don't publish official per-app totals, so counts vary by provider and month — verify before citing.
The pecking order of the world's phones changed in a way almost nobody predicted three years ago. For the better part of a decade, the title of "most downloaded app on Earth" bounced between TikTok, Instagram, and Facebook. In 2025 an AI chatbot muscled its way to the front. This ranking of the most downloaded apps 2026 is ordered by estimated global first-time installs across the App Store and Google Play for full-year 2025, and at the top sits ChatGPT. One honesty note up front: no one outside Apple and Google sees the real numbers, so everything below is a best-available estimate compiled by app-intelligence firms, the counts move around, and the providers don't fully agree — Sensor Tower's full-year data ranks TikTok first and ChatGPT second, while Apptweak's puts ChatGPT on top. We follow the Apptweak ordering here and flag the disagreement where it matters. Last updated: July 2026.
1. ChatGPT
Estimated global downloads: roughly 845 million-plus across full-year 2025 (Apptweak). OpenAI's assistant is the reason this whole list looks different from a year ago. It grew well over 100% year on year — Sensor Tower pegged its download growth around 148% — helped by viral moments like the Ghibli-style image trend and steady feature drops. It lands at #1 on Apptweak's annual chart, ahead of Instagram and TikTok. Worth repeating: Sensor Tower's full-year ranking instead put TikTok first and ChatGPT second, so the top spot is genuinely close and depends on whose model you trust.
2. Instagram
Estimated global downloads: around 760 million. Meta's photo-and-Reels platform remains an install magnet, especially across emerging markets where new smartphone owners set it up early. It sits at #2 on Apptweak's 2025 annual chart, though its own installs fell an estimated 19% year on year — a strong absolute number in a shrinking market.
3. TikTok
Estimated global downloads: roughly 545 million. The former download champion slipped a spot on Apptweak's chart, with installs down around 12% year on year, yet it still pulls hundreds of millions of fresh installs. On engagement and time-spent it arguably still leads the world, and by Sensor Tower's count it remained the single most downloaded app of 2025 — this list ranks installs on one provider's model, not hours.
4. WhatsApp
Estimated global downloads: around 540 million. Meta's messenger is the quiet giant — the default communication app across much of Latin America, Africa, South Asia, and Europe. It posted a year-over-year download decline of roughly 18%, which is what you'd expect from an app already installed on almost every phone that will ever want it. Saturation, not weakness, explains the dip.
5. CapCut
Estimated global downloads: around 500 million. The breakout non-social entry. ByteDance's free video editor is the workshop behind a huge share of the short-form clips people watch elsewhere. Creators install it to trim, caption, and polish videos for TikTok, Reels, and Shorts, and that utility role keeps it inside the top five. It's proof that creator tools are now a download category of their own.
6. TikTok Lite
Estimated global downloads: around 430 million. The stripped-down, low-data version of TikTok is built for slower networks and cheaper phones, which is exactly where a lot of the world's next billion users are. Counted separately from the main app, it lands in the middle of the pack on its own — a sign of how much growth still comes from data-conscious and emerging markets.
7. Netflix
Estimated global downloads: around 415 million. The streaming leader keeps refilling its install base as subscribers switch phones, re-verify accounts, and sign up in newer markets. Its cheaper ad-supported tier widened the funnel, helping it stay near the top of the entertainment category and comfortably inside the overall top 10.
8. Facebook
Estimated global downloads: around 408 million. The original social juggernaut is deep into maturity. New installs skew toward first-time smartphone users in developing regions rather than saturated Western markets, and its downloads fell sharply — an estimated 23% year on year. Still, "past its download peak" and "eighth-most-downloaded app on the planet" can both be true at once.
9. Temu
Estimated global downloads: around 390 million. The bargain marketplace from PDD Holdings spent 2023-2024 carpet-bombing app stores with aggressive ads and topped several country charts. In 2025 its downloads cooled — about 8% year on year — as ad spend normalized and some markets tightened rules, but the sheer scale of its earlier push keeps it in the top 10.
10. Snapchat
Estimated global downloads: around 385 million. Snap rounds out the list on the strength of its grip on younger users — the camera, the lenses, the streaks. Its download base is remarkably durable in the US, Europe, and parts of the Middle East and South Asia, even as bigger rivals chase the same teens. A steady #10 is a respectable place to close a brutally competitive chart.
The 2026 ranking at a glance
| Rank | App | Est. global downloads (2025, full year) | Note |
|---|---|---|---|
| 1 | ChatGPT | ~845M+ | First AI app to lead; Sensor Tower ranks it #2 |
| 2 | ~760M | Down ~19% YoY; strong in emerging markets | |
| 3 | TikTok | ~545M | Still tops engagement; Sensor Tower's #1 |
| 4 | ~540M | Down ~18% YoY; near-total saturation | |
| 5 | CapCut | ~500M | Video editor behind short-form clips |
| 6 | TikTok Lite | ~430M | Low-data build for emerging markets |
| 7 | Netflix | ~415M | Ad tier widened the funnel |
| 8 | ~408M | Down ~23% YoY; growth skews to new users | |
| 9 | Temu | ~390M | Cooled ~8% after ad-driven surge |
| 10 | Snapchat | ~385M | Sticky with younger users |
The pattern jumps out of the table: an AI app at or near the top, a wall of social platforms behind it, and two tools — CapCut and, arguably, ChatGPT itself — muscling in on territory that used to belong entirely to social networks. Total installs across the top apps actually slipped year on year — Apptweak put the top-500 decline near 5% — so this isn't a rising tide lifting everyone. Growth concentrated at the AI end while several legacy names quietly declined. For more rankings like this, browse our top 10 lists or head back to Countly.
Frequently asked questions
What is the most downloaded app in the world in 2026?
By global first-time installs, ChatGPT is the most downloaded app heading into 2026 on most annual rankings. Across full-year 2025 it drew an estimated 845 million-plus downloads worldwide (Apptweak), pulling ahead of Instagram and TikTok. Note that Sensor Tower's full-year data instead ranks TikTok first and ChatGPT second, so treat the exact order as an approximation and verify against the latest App Store and Google Play intelligence before citing.
Did ChatGPT really overtake TikTok?
It depends on the source. Apptweak and several other providers reported that ChatGPT became the single most downloaded app of full-year 2025, moving ahead of TikTok, which had led in prior years. Sensor Tower, using its own model, still put TikTok at #1 for the year and ChatGPT at #2. Either way, ChatGPT clearly led the monthly charts for stretches of 2025 and topped Apple's US chart. This all ranks apps by new installs, not by active users or time spent — TikTok and Instagram still lead on engagement.
Are these numbers exact download counts?
No. They are best-available estimates compiled by third-party app-analytics firms that model installs from sampled data; Apple and Google do not publish official per-app totals. Figures differ between providers and shift month to month, so we present rounded numbers. Always check the most recent source before quoting a precise figure.
Why is CapCut ranked so high?
CapCut, ByteDance's free video editor, benefits from the short-form video boom — creators install it to edit clips for TikTok, Instagram Reels, and YouTube Shorts. That utility role drives huge repeat and first-time installs, keeping it inside the global top five in 2025-2026 despite being a tool rather than a social network.
Which apps are declining in downloads?
Several long-established apps posted year-over-year download drops in 2025, including Instagram, TikTok, WhatsApp, Facebook, and Temu, even while staying in the top 10 — Facebook fell roughly 23%. Total installs across the top apps dipped a few percent as the market matured, and growth concentrated in AI assistants and creator tools rather than legacy social platforms.
How often does this ranking change?
Frequently. Download charts move month to month with app updates, viral moments, marketing pushes, and regional trends. A short-form editing tool or a new AI feature can reshuffle positions within a single quarter, so this list reflects a 2025-into-2026 snapshot rather than a fixed order.
Methodology and disclaimer: This ranking is compiled from third-party app-intelligence estimates covering combined iOS and Android first-time installs, following Apptweak's full-year 2025 global ordering; Apple and Google do not release official per-app download totals. Providers disagree — notably, Sensor Tower's full-year data ranks TikTok #1 and ChatGPT #2, the reverse of the top two here. Figures are approximations that vary by provider and change over time, and the order can shift from month to month. Treat every number here as a best-available estimate as of 2026, and verify against the latest primary source before citing.
