The Email Apps Worth Downloading on iPhone and Android
Outlook leads with 951K ratings, while Gmail, Aqua Mail and Edison Mail cover different inbox habits without needless clutter.
Quick Picks
Best overall: Microsoft Outlook.
Best for Gmail users: Gmail.
Best Android alternative: Aqua Mail.
Best for inbox cleanup: Edison Mail.
The email-app hunt produced one obvious winner and several useful specialists. Outlook has the strongest evidence behind it with 4.7 stars from 951K App Store ratings, while Gmail follows at 4.6 from 118K. The smaller third-party apps need more caution: some have only three ratings, so a perfect score is not proof of quality.
The dependable daily inboxes
Email apps have settled into two camps: full productivity hubs and focused inbox tools. Outlook and Gmail belong to the first group, while Apple Mail remains the quiet default for people already using several account types. The surprising part of this hunt is how much stronger the established apps look in the ratings data; the newer alternatives often have too little feedback to justify switching on reputation alone.
Microsoft Outlook
Outlook is the clear editorial pick because its 4.7-star score comes from 951K Australian App Store ratings, not a tiny sample. The listing positions it as email, calendar and file management in one app, which gives it more practical range than Gmail alone. It is free to download with in-app purchases, and it sits at No. 15 in the App Store Productivity chart. That combination makes Outlook the safest recommendation for people managing work and personal accounts across Microsoft services. The downside is focus: if you only need a clean Gmail inbox, its broader calendar-and-files approach can feel heavier than necessary. Best for office workers, Microsoft 365 users and anyone who wants email and scheduling in one place.
Gmail
Gmail gives Outlook its closest serious competition, particularly for people already living inside Google services. It carries 4.6 stars from 118K App Store ratings and is listed as free with in-app purchases, with the store description focusing on secure, fast and organised email. Outlook has the larger rating base and a stronger all-in-one productivity pitch, but Gmail is the simpler pick if your accounts, contacts and work habits already sit with Google. The catch is that the provided listing does not show a price for paid features, so value depends on which Google services you already pay for. Best for Gmail-first users who want a familiar inbox on iPhone without moving their workflow.
Apple Mail is the understated option in this group, but its account coverage is broad: the listing names iCloud, Gmail, Exchange, Yahoo and Outlook, among other providers. It also lists scheduling, snoozing, unsending, Priority Messages and summaries powered by Apple Intelligence. That feature mix makes it more capable than the basic default-app label suggests. Compared with Outlook and Gmail, though, the supplied data does not include an App Store rating or price, so there is less public evidence to support a quality verdict. Best for iPhone owners who want one native inbox across several providers and prefer built-in tools over another standalone account.
Edison Mail
Edison Mail is the specialist pick for people whose inbox feels like a rubbish tip. Its App Store listing centres on spam reduction and inbox zero, and the app has 4.5 stars from 2.6K ratings. That is a respectable result, though the sample is far smaller than Outlook's or Gmail's. The trade-off is scope: the listing does not present the same calendar-and-files breadth as Outlook, so it makes more sense as a focused inbox tool than a complete productivity suite. Best for users who receive too much promotional mail and want cleanup features to sit at the centre of the experience.
Aqua Mail
Aqua Mail is the strongest Android-specific find here because its listing names support for Gmail, Outlook, Hotmail, Yahoo Mail, iCloud Mail, Exchange, Office 365, IMAP and POP3. It has passed 5 million downloads, and the provider describes it as free, customisable and backed by human support. That breadth beats the iPhone-only alternatives below, especially for anyone with less common mail-server requirements. The missing piece is a visible rating in the supplied data, so the download count proves reach rather than satisfaction. Best for Android users with several providers, Exchange accounts or advanced IMAP and POP3 needs.
Outlook wins the evidence battle, but Aqua Mail shows why platform matters. iPhone users have polished mainstream choices; Android users gain a more configurable multi-provider client. The next group is less convincing, because small rating samples and vague positioning make switching harder to justify.
Third-party inboxes: useful idea, thin proof
Several apps in the hunt promise one login for multiple accounts. That sounds convenient, but an email client handles sensitive messages, so a low rating count is not a minor detail. Three ratings can tell you almost nothing.
All Email Access
All Email Access is the weakest find in the group, and the numbers are blunt: just three App Store ratings produce a 1.0-star score. Its subtitle promises an email app for Gmail and Outlook, but that is not enough differentiation against the established apps, particularly Outlook and Gmail themselves. The 18+ age rating also deserves a pause because the supplied listing gives no explanation for it. I would not hand this app access to a primary inbox without much more evidence about its developer, permissions and handling of account data. Best for testers with a spare account, not anyone managing important personal or work email.
Hotmail
Email for Hotmail, Outlook lands in the middle: 3.4 stars from 116 ratings, free with in-app purchases and designed for iPad, though not verified for macOS. Its narrow Hotmail and Outlook focus could appeal to someone who wants a dedicated client, but Outlook itself already covers those accounts with a much larger 4.7-star evidence base. The rating gap matters more than the app's generic promise of support. Best for an iPad user who has tried Outlook and prefers a simpler dedicated interface, but it is difficult to recommend as a first download.
The smaller clients are not automatically bad; they are simply under-proven. A perfect score from three people should not beat a 4.7 from 951K, and a 1.0 from three ratings should not be treated as a complete technical review. The final pick is a newcomer with almost no track record, which makes its position useful mainly as a watchlist entry.
New arrivals and the evidence problem
Fresh apps can bring cleaner design or a better account workflow, but email is a poor category for blind experimentation. You are handing over access to private correspondence, attachments and contacts. A polished store subtitle is not enough.
Mailbird
Mailbird is the intriguing newcomer, but the evidence is extremely thin: one App Store rating at 5.0. Its subtitle promises one inbox, yet the supplied listing does not provide enough detail about account support, privacy controls, pricing or platform reach to put it ahead of the established choices. That single rating may reflect a happy early user, but it cannot establish reliability. I would keep Mailbird on a watchlist rather than make it the main inbox for a busy work account. Best for early adopters willing to test a new iPhone email client with a secondary account.
Final verdict: start with the proven clients
Outlook is the best all-round download in this set. Its 4.7 stars from 951K ratings, calendar and file positioning, and strong chart placement give it the most credible combination of quality and range. Gmail is the better call for people already anchored to Google, while Apple Mail keeps things simple for iPhone owners with accounts spread across several providers.
Aqua Mail earns the Android recommendation for its unusually broad provider support and 5 million-plus downloads, although the missing rating data means it deserves a measured trial rather than blind loyalty. Edison Mail is the focused inbox pick. The tiny third-party clients are the ones to approach carefully: their ratings are either too low or too small to carry much weight.
My shortlist is simple: choose Outlook for work, Gmail for a Google-centred setup, Apple Mail for native iPhone simplicity, Aqua Mail for Android flexibility and Edison Mail for inbox cleanup. Once your email is under control, the next productivity question is money management; The Budgeting Apps That Actually Help With Tax Time covers the apps that turn financial admin into a less painful routine.
