The App Store has millions of apps, which means the best ones are often buried under paid alternatives and mediocre freemium products. After years of testing, these ten stand out as the genuinely best free apps available in 2025 — the ones that make a real difference to how you work and live.
1. Bitwarden (iOS, Android, Desktop, Browser)
Password management is the single most impactful security improvement most people can make, and Bitwarden is the best free password manager available. It's open source, end-to-end encrypted, works on every platform, and stores unlimited passwords — all completely free. The browser extension fills in passwords with one click. If you only download one app from this list, make it Bitwarden. Create an account, install it on your browser and phone, and spend 20 minutes importing your existing passwords. It's genuinely life-changing for anyone who's been reusing passwords or struggling to remember dozens of different ones.
2. Brave Browser (iOS, Android, Desktop)
Brave is a Chrome-compatible browser that blocks all ads and trackers by default, without any extensions or configuration needed. The result is a noticeably faster browsing experience — pages load faster because they're not loading tracking scripts and ads — and meaningfully better privacy. Because it's built on the same Chromium engine as Chrome, all your Chrome extensions work and websites behave identically. Brave also has a built-in Tor private browsing mode for extra privacy when needed. For anyone concerned about privacy or just tired of intrusive ads, switching your default browser to Brave is a five-minute change that pays dividends every day.
3. Signal (iOS, Android, Desktop)
Signal is the gold standard for private messaging. End-to-end encrypted by default, open source, and run by a non-profit that has no financial incentive to monetise your data. It handles SMS, voice calls, video calls, and group messaging — everything WhatsApp does, but with much stronger privacy guarantees. The interface has matured significantly and is now as polished and easy to use as WhatsApp or iMessage. The "disappearing messages" feature automatically deletes messages after a set time period. If you have conversations you'd prefer to keep genuinely private — with your doctor, lawyer, or simply in your personal life — Signal is the right tool.
4. Notion (iOS, Android, Desktop)
Notion is the most powerful free productivity app available. It combines notes, tasks, databases, wikis, and project tracking in one flexible interface. The same tool can be a simple daily journal, a project management board, a knowledge base for your team, or a content calendar. The learning curve is real — Notion has a lot of depth — but even using just the basics (pages and simple databases) is transformative for organisation. The free plan is genuinely generous, giving you unlimited personal pages and blocks. If you currently use a combination of Notes, Reminders, Google Docs, and Trello, Notion can consolidate all of them.
5. Libby (iOS, Android)
Libby is one of the best-kept secrets in apps. It's an app by OverDrive that lets you borrow ebooks and audiobooks from your public library for free, directly to your phone or Kindle. All you need is a library card. Most major cities have extensive digital collections — thousands of ebooks and audiobooks available to borrow instantly or with a short wait. For regular readers, this is genuinely extraordinary: access to a massive library of free books in your pocket. If you pay for Audible or buy Kindle books regularly, Libby can save you hundreds of dollars a year.
6. Flighty (iOS)
For anyone who travels by air even occasionally, Flighty is indispensable. It tracks your flights in real time, showing gate changes before the airport announcements, accurate delay predictions based on where your aircraft currently is and its history, and push notifications for anything relevant to your journey. The free tier covers the basics. What makes Flighty remarkable is its accuracy — it consistently has information faster than airline apps and airport displays. The difference between knowing your gate has changed 30 minutes before boarding and finding out at the last minute is the difference between a calm travel day and a stressful sprint.
7. Duolingo (iOS, Android)
If you've ever wanted to learn a language but never found a method that stuck, Duolingo is worth trying. Its gamified approach — streaks, XP, leagues — is surprisingly effective at building the habit of daily practice. The free version is fully functional; the premium tier just removes ads and adds some extra features. 15 minutes a day is enough to make meaningful progress over months. It's not a complete language learning solution on its own, but as a daily habit that builds vocabulary and grammar intuition, it's hard to beat for free accessibility.
8. Canva (iOS, Android, Web)
Canva makes visual design accessible to people with no design training. Create social media posts, presentations, flyers, posters, video thumbnails, resumes, and more using a drag-and-drop interface with thousands of templates. The free tier is extensive and includes access to most templates, basic AI features (Background Remover, Magic Write), and hundreds of thousands of stock photos. If you've ever paid for a designer to create something simple, or struggled with PowerPoint to make something look decent, Canva is worth spending an afternoon exploring.
9. Google Photos (iOS, Android)
Google Photos automatically backs up every photo and video you take, creates albums, and uses AI to make everything searchable. Search "beach 2022" and it finds your beach photos from 2022. Search "Maya" and it finds photos of your friend Maya across years of photos. The free 15GB is shared across your Google account — once it's full, you pay for Google One storage. But even at the free tier, the automatic backup and search functionality alone make it the best photo app available. The "Memories" feature resurfaces old photos on their anniversary, which many people find genuinely delightful.
10. Perplexity AI (iOS, Android, Web)
Perplexity AI is the future of search. Instead of a list of links, it reads current web pages and gives you a synthesised answer with inline citations. Ask it "What's the best way to treat a pulled muscle?" and it gives you a clear, sourced answer rather than 10 links you'd have to read yourself. Ask it anything research-related and it behaves like having a research assistant who reads everything and reports back. The free tier is generous and handles most everyday queries well. For anyone who spends a lot of time searching and reading web pages to find answers, Perplexity dramatically compresses that time.
