A daily app for self-alignment, wisdom and reflection, for anyone who wants to show up as their best self every day. Read a verse from the Stoics, the Bible, the Quran, the Buddha, the Guru Granth Sahib, Confucius and other great religious leaders, poets and philosophers. Morning and evening, write a few honest lines about how you are and what you're grateful for, and choose one thing to finish today. A 24/7 AI/SI wisdom Guardian (SI: Super and Spiritual Intelligence) answers your questions on any quote and keeps you accountable to your goals and vision. Tuning practices shift your state and bring you back into alignment with your best self. Now on Apple Watch. WHAT SIX EIGHT (6/8 OR 6:8) MEANS: 6 is your outer life: work, health, money, habits and relationships. It asks what you need to do. 8 is your inner life: faith, meaning, reflection and presence. It asks who you are becoming. Six Eight (6/8) keeps both on the same page. WHAT'S INSIDE: DAILY WISDOM Stoic quotes, Bible verses, passages from the Quran, poetry and philosophy. Search by author or theme, listen to any line, or turn it into today's action. 5 MINUTE JOURNAL Morning and evening check-ins, plus a journal you can write in or talk to. Use it as a Stoic journal, a gratitude journal or a prayer journal. Voice entries are transcribed on your device, and Private entries stay locked behind Face ID or your passcode. TEMPLE Prayers from Christian, Jewish, Muslim, Hindu, Buddhist, Sikh and Taoist traditions, guided breathing, gratitude, a vision board, your values and purpose, and a short list of what has to happen today. ALIGNMENT SCORE AND PATHS A quick daily check-in becomes a score with weekly and monthly trends, so you can see whether what you read turns into what you do. Paths offer guided journeys, and a 7-day Journey walks you through your first week. WHAT'S PULLING ME When a craving, a comparison or an old reaction takes hold, name it, read a line that fits and pick one small action. APPLE WATCH Today's wisdom on your wrist. Speak or type your morning and evening entry and it syncs to your iPhone journal. Check your Alignment Score, read prayers offline with Hold to Amen, and take a guided breath. ALSO INCLUDED Home Screen and Lock Screen widgets, share cards for any quote, and light or dark mode. 6/8 PRO New members start with a free trial on the yearly plan. Your membership includes: • The Guardian, an SI guide to talk things through with, including what a line means for your life. It can remember what matters to you, and you can read or delete those notes any time. • Meaning and Action: a deeper read on any quote • Unlimited Keeps, Deck swipes and What's Pulling Me • Every tradition and genre filter, plus rarity and reading length • The Cinema view, premium scenes and app icons • On the yearly plan, your own morning and evening check-in question PRIVATE BY DESIGN No ads. Journal entries are encrypted on your device, and Private entries, photos and voice recordings never leave it. Before your first Guardian conversation, the app shows what will be sent to the SI (AI) and waits for your OK. Six Eight is a reflection practice, not therapy, medical care or a substitute for professional support. SUBSCRIPTION 6/8 Pro is an auto-renewing subscription with weekly, monthly and yearly plans. Your plan renews automatically unless auto-renew is turned off at least 24 hours before the current period ends. Your price and any introductory offer you are eligible for are shown before you confirm, and payment is charged to your Apple Account at confirmation of purchase. Manage or cancel in your Apple Account settings. Privacy Policy: https://sixeightapp.com/privacy Terms of Use: https://sixeightapp.com/terms

Verdict
iCardio Workout Tracker and 6 both sit at 4.8 stars, but that hides the real split: 100% of 6's written reviews are positive against 63% of iCardio Workout Tracker's. 6 also leads on update cadence (every 2 days vs every 11 days). iCardio Workout Tracker's advantage is ads (none vs shown) and ratings volume (3.4K vs 1). On price, rating, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. iCardio Workout Tracker sells 4 in-app purchases, starting at $4.99 per month and 6 sells 6 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.
6 holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: iCardio Workout Tracker has 3.4K ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 63% of iCardio Workout Tracker's written reviews are positive against 100% of 6's.
iCardio Workout Tracker ships an update every 11 days, 6 every 2 days. The most recent releases landed on October 21, 2026 and October 28, 2026 respectively.
