It’s a struggle to know what really makes you happy. Our primitive brains are fundamentally ill-equipped to compute all our habits, achievements, aspirations and values. By keeping a log of how you feel while you feel it you can go beyond your inner dialogue to discern patterns of mood and behaviour. This app provides evidence-based and non-judgemental insight into what it is that really makes you happy. Mood tracking for busy people: Write your diary every day and say as much as you feel • Hashtag support to add structure or for quicker entries • Apple Watch support for the quickest entries • Dark and light mode support for maximum comfort • Randomised daily reminders • Scheduled reminders if you want to get into a journaling habit • Machine learning does some basic sentiment analysis to give you a gentle tail-wind when discerning your mood • Timeline and search features make it easy to explore your diary, with starred entries always visible for a "condensed narrative" • Sensitive entries can be marked private and will be blurred out and locked on your timeline so you nobody accidentally sees anything over your shoulder • Location can be automatically recorded with every entry • Useful tools to manage and organise your entries and hashtags Insights: As you add more data, more insights are unlocked • At a glance insights in words and charts help you quickly see your progress • Augmented Reality infographics let you deep-dive into large data sets without any pinching, swiping, tapping or scrolling - just move your phone around to explore • When you discover something interesting, take a picture to save to your Photos or share with others • Word clouds let you see what's been on your mind the most • Location map lets you see where you have been happiest • My Story insight lets you see all of your data at once with lanes of hashtags and a detailed day-by-day calendar. Take Action - make a change! • When you have enough data you can try making a change in your life • See how your story unfolds and whether you made your life better or worse You own your data • iCloud sync • Export JSON or your whole database • We don't do analytics without your permission and we tell you exactly what we collect This is the third evolution of my 'happiness app' concept since 2009 (or fifth, depending on how you count it). When I first started tracking my mood I didn't know what to expect. Now I have a pretty good idea of the biggest strengths of this mechanism and I've collected and bundled all of my insights in to this app, just for you. I hope you'll give it a try.

Upcurve

Upcurve counts the days you showed up, not the streak you broke. Your steps and workouts flow in from Apple Health and turn into charts on their own; water, reading and anything else take one tap. And when a goal gets easy, raise it. Upcurve applies progressive overload — the principle behind strength training — to everyday habits. Start at 2 L of water, 20 minutes of reading, or 3×30s dead hangs. Your chart draws a stepped goal line that climbs with you, and your daily bars tell the honest story of how you rose to meet it. APPLE HEALTH, BUILT IN • Steps flow in automatically as a free habit — you never type a step. • Every workout, by activity type — strength, running, yoga, and more — charted over weeks and the whole year, not just today's numbers. • Water syncs both ways — log in Upcurve, see it in Health; log in another app, see it in Upcurve. Duplicates are filtered out. • Health data is read on your iPhone and never leaves it. NO STREAKS, BY DESIGN A single missed day shouldn't erase months of work. Instead of a streak, Upcurve shows consistency — the percentage of days you met your goal. Miss a day and the number dips slightly; it never resets to zero. TRACK ANYTHING, HONESTLY • Quantity habits with real units: liters, milliliters, minutes, pages, or your own. • Sets × duration habits for training: 3×45s dead hangs, planks, stretches. • Log any amount — above or below goal — and correct any past day. Honest data beats a tidy but false record. • A built-in timer with a Live Activity in the Dynamic Island, which logs the time you actually did. QUICK TO LOG, EVERYWHERE • One-tap quick add, remembered custom amounts, and a complete-goal button. • Home Screen and Lock Screen widgets. • Siri and Shortcuts: "Log water in Upcurve." • Reminders with quick-log buttons that work from your wrist. YOUR DATA STAYS YOURS No account. No servers. No tracking. Everything lives on your device, and you can export it as JSON anytime. FREE AND PRO Free: 4 habits (plus a free steps habit), full logging, 30 days of charts.
