Less stressed. More resilient. Healthier. Flowtime app has scientifically validated lessons made by renowned guides on various topics. The free timer mode makes the app compatible with other apps. That helps you record data with just one app while you listen to audio from other apps. Fill your goal rings with whatever audio you listen to. While practice is made easy, it's simple to make meditation your new habit. # SCIENTIFICALLY VALID LESSONS Meditation helps us relax while guided lesson matters. Flowtime lessons were validated scientifically to improve stress resilience in a randomized controlled trial completed in collaboration with Mobio Interactive and the University of Toronto. There are about 120 sessions from professional meditation instructions, including courses engaging in relationships, performance, stress, leadership, focus, anxiety, mindful pregnancy, and so on. # IMMERSIVE GUIDED BREATHING TRAINING Experience mindful immersion with our innovative audio, visual, and vibration guidance. Make it easy even for beginners to cultivate calm awareness in the present moment and prevent the mind from wandering. # GOAL TRACKER RINGS Tracking your goals daily makes meditation feel more real and less like an abstract, unattainable concept. It's a small step that can really make a difference in achieving your goals. Every minute you practice counts automatically towards closing the ring. # FREE TIMER MODE When you are still finding the audio that suits you from different apps and platforms, it's essential to record all the practice in one app. Start timer mode, you are free to listen to any lessons from Insight Timer, Calm, Headspace, or even YouTube. Every minute you practice counts in the goal trackers. # BIOFEEDBACK MEDITATION Know you're getting there as you hear the sound that verifies your desired state, whether it's flow, breath coherence, alpha or theta status, or focused concentration. No more guesswork or relying solely on feelings. There are 11 metrics available to set up. # VISUALIZED RICH BIODATA REPORT The real-time data matters when you are doing meditation, while rich biodata reports after practice are also crucial to measuring your practice every time and insights into your progress. The sensors passively sense your brain and heart activities, and the app translates them into visualized graphs of your body performance. You will be eager to see how well you perform after you practice. # MONTHLY & YEARLY REPORT Trends help us see the big picture when small changes add up. They make it easier to spot important changes. Some metrics like HRV can be less responsive, so it's better to look at them on a monthly or yearly basis. **You can use the Flowtime app alone or with the Flowtime headband, which is available to purchase in the app.** With your permission, Flowtime can write Mindful Minutes on the Apple Health app for health tracking. If you have any questions, please feel free to contact us. You can send feedback on the app or email us.

Verdict

The call

The clearest difference is rating: Opti Train at 5.0 against Flowtime's 4.3. Opti Train also leads on iOS requirement (13.0 vs 15.0). Flowtime's advantage is monetization model (free with in-app purchases vs subscription) and ratings volume (206 vs 3). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Opti Train sells 2 in-app purchases, starting at $9.99 per month and Flowtime sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Opti Train holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Flowtime has 206 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 33% of Opti Train's written reviews are positive against 45% of Flowtime's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Opti Train ships an update every 2 months, Flowtime every 2 weeks. The most recent releases landed on November 2, 2026 and November 11, 2026 respectively.
