Best meditation apps: For finding calm and quiet
Headspace: Your guide to mindfulness

Free from Apple and Android, ad-free subscriptions available.
Headspace is an excellent choice for beginners with no prior meditation experience. The app walks you through the entire process with the goal of helping you build a consistent meditation practice for your daily life. You’ll be able to work through basic or advanced courses that teach foundational skills. Grounding exercises, breathing techniques, and visualizations are only a few of the techniques Headspace can teach you. Plus, its short "SOS" sessions are perfect for managing seasonal stress too.

Headspace offers a free version, but be prepared for frequent messages encouraging you to upgrade to its $12.99/month premium subscription. If you decide to upgrade, the paid plan includes the full library of themed meditations, sleep guidance, and expert-level exercises.
Unlimited data for your mental well-being
Staying connected to your mental health apps requires a consistent data connection. An unlimited data plan removes the stress of monitoring your usage and running out of data.
Rest assured that you can join a live therapy video call, download a new meditation pack, or check in with your support community at any time with unlimited data. Read up on mobile data usage in our guide to see how much data you really need for your digital habits.

Happier Meditation: Mindfulness for skeptics

Free trial on iPhone and Android, subscribe for $14.99/month to continue.
Happier (previously known as Ten Percent Happier) is designed for anyone curious about mindfulness but skeptical of overly spiritual approaches. The app focuses on practical meditation plans and straightforward courses taught by respected teachers and scientists. Its topics are highly specific, with plans like "Managing Anxiety" and "Dealing with Difficult Relatives.”
Image: Jessica Santero | WhistleOut
The app provides a free trial to get you started, but full access to its entire library of courses and podcasts requires a $14.99/month subscription. You can learn from a diverse group of expert teachers on Happier, not just a single instructor. The app organizes teachings into structured courses that begin with introductory videos. You can easily meditate on the go, too. It's the best choice if you want to understand how and why meditation works.
Best apps for stress and anxiety relief
Happify: Building resilience through activity

Free from Apple and Android. Premium costs $14.99/month.
Happify offers a unique, interactive approach to building mental resilience, or the ability to bounce back from life's challenges. Instead of traditional meditation, it uses science-based games and activities to help you reframe negative thoughts.
The Happify process begins with very detailed questionnaires that create a personalized track based on your current mental state and goals. As you complete different exercises and sessions, the app walks you through each step in your therapy. My personal track was geared to workplace focus and advancement goals.
Image: Jessica Santero | WhistleOut
Get started with Happify’s free activities. While they may be limited, at least you can enjoy a small selection of exercises to begin your healing journey today. However, the $14.99/month paid subscription unlocks the platform's full depth, including unlimited access to all its different pathways and games. If you’re looking for therapy with qualified individuals, Happify might not be the best pick. This app relies on pre-programmed AI responses rather than a live coach. That said, Happify is a refreshing and effective alternative if you want a more active, data-driven way to build mental strength.
Don’t stress over your phone bill. Switch to an MVNO and save.
You can get the same reliable coverage you're used to without the premium price tag. Mobile virtual network operators (MVNOs) use the same major networks as Verizon, T-Mobile, and AT&T, but they offer plans at a fraction of the cost. This means you can get consistent service for calling, texting, and using your favorite mental health apps, all while enjoying predictable billing with no surprise fees or overage charges.
Here are the best MVNO plans on the market:
Clarity: CBT self-help journal with science-backed therapy

Clarity is a smart mental health journal that tracks your moods and thoughts, not just a depression app. Its data-driven method helps you see your mental well-being improve over time. By using Cognitive Behavioral Therapy (CBT) to explain your habits, Clarity gives you insights into why you act and respond the way you do.
The process begins with a detailed introductory questionnaire that the app analyzes to map your starting point. As you progress, it provides clear visuals and graphs of your therapeutic evolution. This guided process walks you through each step, making the journey of self-improvement feel structured and supported.

After testing several therapy apps, Clarity was the only platform that offered analytic graphics of my projected evolution backed by science. It’s the best free therapy app, so you can get help at no cost.
Best online therapy apps for professional support
Talkspace: Full access to a licensed therapist

Available on iPhone and Android. Pricing varies depending on your sessions.
Talkspace directly connects you with a licensed therapist for help around the clock. Unlike other self-guided AI therapy apps, it actually matches you with a professional from a variety of specialties. Talkspace offers therapy for adults, teens, and even couples.
After a short assessment, you can message your therapist via text, send audio notes, or connect over video at any time. It’s convenient since you can contact a professional to share your feelings in real-time after a stressful event or conflict. Better yet, if your preferred therapist isn’t available, there is always another health professional you can count on.
Image: Jessica Santero | WhistleOut
Talkspace lets you choose your therapy based on your budget. You can choose text-based messaging or opt for live sessions in your plan. Pricing varies depending on the services you choose. The good news is your insurance provider might cover the costs. Make sure to check out your in-network options and included programs. While therapy in itself is a financial investment, Talkspace provides personalized support that free apps don’t offer.
Treat yourself to a bigger screen for live sessions
Upgrading to a phone with a larger, more immersive screen can transform your teletherapy experience. A bigger display makes it easier to focus and feel truly present during your sessions, helping you stay engaged and accountable to your mental health goals. With this clearer, more personal connection to your therapist, you won’t feel like you're missing the benefits of an in-office visit.

BetterHelp: Flexible and accessible counseling

Available on iPhone and Android. Pricing varies by session.
BetterHelp has become one of the most recognizable online therapy platforms on the market. You may have even heard about it (just like I did) from your favorite YouTubers. BetterHelp is the top therapy app due to its therapist-matching system. Whether you're navigating family conflict, struggling with grief, or feeling anxiety, you can count on this app to get you the best help.
Image: Jessica Santero | WhistleOut
BetterHelp provides support through individual video sessions, all-day chat, messaging for crises, and even group webinars. Expect to pay by the session, so pricing varies. That said, you can find therapists who offer services for every budget.
Once you connect with a professional, you also get access to BetterHelp’s unlimited messaging and regular live sessions.
As a dedicated channel to professional care, it offers accessible help during demanding seasons.
7 Cups: Find a listener or join a support community

Free versions from Apple and Android. More features with the $12.99/month subscription.
7 Cups specializes in immediate emotional support through its community. You can join live, anonymous chat rooms for group support or connect one-on-one with a trained listener for a private conversation—all for free. You can also opt for more structured guidance on 7 Cups as well. The premium subscription costs $12.99/month for access to therapy sessions with licensed professionals.
Image: Jessica Santero | WhistleOut
The free tier makes 7 Cups a vital resource for combating loneliness, stress, and seasonal depression. We all have moments when we simply need a compassionate ear during stress. While you can pay for professional therapy sessions, the platform's community-driven support offers real connections when you need them most.
Best apps for sleep (or when you can't turn off your brain)
Calm: For sleep and serene moments

Free trial on iPhone and Android. Subscribe for $16.99/month.
Calm serves as a dedicated sleep and relaxation app that you can access from any device. It’s the only meditation platform that boasts a library of high-quality audio sleep aids and is one of the best brain health apps on the market.
I really appreciated its narrated "Sleep Stories" voiced by celebrities in Calm’s free trial. It was very soothing to hear voices I recognized from the Silver Screen in my earbuds while resting in bed. If you don’t want voices, you can opt for immersive soundscapes or curated music playlists for meditation.

Image: Jessica Santero | WhistleOut
It's important to know that Calm operates almost entirely as a subscription service, with its premium plan costing $16.99/month. It’s one of the more expensive meditation apps on the market, but it’s worth it if your main goal is to effectively combat stress—and get a good night’s sleep.
Downgrade to a dumbphone for better sleep
Switching to a basic phone can be the simplest and most effective way to improve sleep. By removing the endless distractions of social media, emails, and notifications, a dumbphone creates a peaceful environment for your mind to unwind. You'll eliminate the blue light from smartphone screens and the mental stimulation of smartphones, making it much easier to fall asleep and enjoy a truly restful night.

Gamified self-care apps
Finch: Your self-care tamagotchi

Finch combines self-care with a virtual pet. You complete real-world self-care goals—like taking a walk, drinking water, or practicing a breathing exercise—to earn energy for your Finch. As you progress, you help it grow and explore a virtual world. This gamified approach provides a tangible sense of reward and motivation, making the concept of self-care feel fun and instantly gratifying. It’s great for building healthy daily routines during chaotic times.

Care for a little bird by meeting your own well-being needs. Completing tasks like taking three breaths, calling a friend, or doing something that makes you happy feeds your bird and helps it grow. To keep you on track, you can add the fInch widget to your phone’s homescreen. You also earn rainbow stones to trade for accessories and furniture, making the reward system even more engaging. While the free version is incredibly generous, the $9.99/month subscription gives you even more customization and access to more accessories.
MyPossibleSelf: Your wellness app

Instead of following a single program, you build your own routine by mixing tasks. They include daily check-ins with breathing exercises, mood journaling, and feeling questionnaires. You can easily adapt your methods to specific stressors, like overspending and relationship tension.

Image: Google Play Store
