Do more in less time with 25-minute blocks. Take it one block at a time and surprise yourself with how much you can accomplish. Inspired by tried and trusted time management techniques. Block & Flow is simple, beautiful and will get your productivity flowing. FEATURES: - A 25-minute visual countdown keeps you focussed and avoiding distractions. - Manage your energy levels with regular breaks - Measure your day, week and longer by how many blocks you finish. - Colour code a block for the activities that you do often or care particularly about. - Goals enable you to be intentional with your time. - History gives you an understanding of where your time goes. - A block’s duration can be changed to your ideal time. WHY IT WORKS: - It makes it easy to get the day started. Just do your first block. - Creates an enjoyment and satisfaction as you see all that you get done. See your blocks build up one by one. - It is clear when to stop. Stop when your block has finished, or after you have done x many blocks for the day. - Every block that you finish is a small success. As these small successes build-up, your self- belief grows. - If you keep finishing your blocks. The time will add up to a lot and you will surprise yourself. (We under-estimate what we can do in the long term). WHO IS IT FOR? People tell me that they do x many blocks a day, or over a week which is fantastic. A few people have been completing their blocks for a year and more. I imagine someone completing their blocks over a month, a year and ultimately many years. I believe they will grow as a person, stretch themselves, and be surprised with what they are able to learn, create and accomplish. This is what excites me and motivates me to do my best for someone that chooses Block & Flow. What will you accomplish, one block at a time?

One rule. Every day. Don't break the chain. Most habit apps drown you in features, charts, and reminders you ignore. Lock In does the opposite. It's built around a single, unbreakable rule: pick your "one do," show up every day, and don't break the chain. Miss a day and your streak resets to zero. That's the whole point — the cost of skipping is what makes you actually show up. HOW IT WORKS 1. Take a 60-second quiz. Tell us your goal, what's been holding you back, and what kind of person you're trying to become. We build a personalized plan around your answers — not generic advice. 2. Sign your pact. Press and hold to commit. "One do. Every day. No skips." 3. Pick your one do. Start tiny — read 10 pages, drink water, walk 5k steps, no phone in bed. The smaller the do, the harder it is to skip. 4. Lock in daily. Open the app, check the box, watch the streak climb. Miss a day? It's gone. Start over. WHAT'S INSIDE – A streak engine that actually means something. No "streak freezes," no second chances, no participation trophies. The rule is the rule. – A custom-designed daily home screen built around your streak — clean, focused, no clutter. – Your Dos: track multiple habits without losing the focus on your primary lock-in. – Streak stats and XP. Watch the chain grow. See how far you've come. – Daily reminders. One ping at the time you choose. Adjustable, optional, and never spammy. – Cross-device sync. Sign in with Apple, Google, or email — your streak follows you everywhere. – Sign in with Apple is fully supported with privacy-respecting authentication. – Premium experience with no ads, no tracking pixels, no dark patterns. WHO IT'S FOR – People who've tried every habit tracker and given up. – Builders, lifters, readers, writers, founders, students — anyone with one thing they want to do every single day. – Anyone tired of streaks that don't matter and "gentle nudges" that change nothing. WHY LOCK IN IS DIFFERENT Most apps soften the rules to keep you happy. Lock In keeps the rules sharp to keep you honest. The streak isn't a number — it's a contract with yourself. The only way to win is to show up. The only way to lose is to skip. That's it. SUBSCRIPTION Lock In offers a yearly and monthly subscription. Cancel anytime in your Apple ID settings. Subscriptions auto-renew unless turned off at least 24 hours before the end of the current period. Payment is charged to your Apple ID account at confirmation of purchase.
