Amazing Marvin is a to-do list and daily planner you can customize, one feature at a time. WHY IT WORKS THIS WAY Different things work for different people. The method that changed your colleague's life can feel like a straitjacket on you. The setup you loved in March can stop working in June. That is normal. So Marvin does not hand you a fixed system. Turn on the features you need, and disable the ones you don't. What users are saying: "So customizable, that when I feel I start to get bored, I can change my flow or strategy & it feels like a brand new app." If you have ever abandoned a setup because you got bored of it, you will love Marvin. PLANNING YOUR DAY - Day planner, where each day gets its own list rather than one endless pile - Duration estimates and a capacity bar that tells you when you have planned more than the day actually holds - Do dates and due dates kept separate, so "work on it Tuesday" is not the same as "it is due Tuesday" - Two-way calendar sync - Week planning, with tasks dragged between days to even out the load - Nested projects and categories, labels, smart lists, recurring tasks - A backburner for someday, kept out of sight of today STARTING IS THE OTHER HALF Knowing what to do and being able to begin are two different problems, and the second is where most days come apart. A lot of Marvin is built for that exact moment: - Accountability Pledge: put money on a task. If you do not finish it, you pay. - Procrastination Wizard: an interactive walk-through of why you are stuck and what to try next - Task breakdown: split something until the first step is small enough to be boring - Super Focus Mode: everything hidden except the one task - The Task Jar: when choosing is the problem, let it choose for you - Dread levels and Eat the Frog, so the thing you are avoiding stops being invisible - Truncated lists, showing two or three items at a time instead of forty KEEPING TRACK, OR NOT Time tracking, Time goals, Pomodoro targets, Habits, Points and Rewards are all here (optional). BUILT WITH LOVE, BY A SMALL TEAM Marvin has been in development for nearly ten years and is still made by a very small team that reads its own support email. It is funded by the people who use it, which is why it has no ads, no data selling and no investors to grow for. ON YOUR PHONE The Marvin phone app syncs with the web and desktop versions. Capture on the bus, plan at your desk, or do all of it from your pocket. Free 14-day trial, no card required. SUBSCRIPTION After the free trial, Amazing Marvin is $11.99 per month or $96 per year. Payment is charged to your Apple ID at confirmation of purchase. A subscription renews automatically unless auto-renew is turned off at least 24 hours before the end of the current period, and your account is charged for renewal within 24 hours before the period ends. You can manage or cancel your subscription in your device settings. Terms: https://amazingmarvin.com/terms.html Privacy: https://amazingmarvin.com/privacy/

Log it when you do it. Remember it when you need it. Most people don’t forget everything. They forget what they need — when they need it. Not because it wasn’t important. But because the details got separated from the moment they belonged to. LogWhen is your simple, private, context-aware memory app. It’s not a to-do list. It’s not a habit tracker. It’s not another overloaded productivity system. It’s one place to log life as it happens — and retrieve it later with clarity. - Why LogWhen? Because you’ve asked: • When did I last change the furnace filter? • What paint color did we use? • What was that gift idea? • When was our last date night? • When did this start? • What did we decide in that conversation? You always remember you need something. You just don’t remember the context — when it matters. LogWhen keeps the who, what, when, where, and why connected. - Features - Unlimited Logs - Unlimited Custom Categories (with color-coding) - Unlimited Custom Relationships (people, pets, vehicles, properties, work roles, etc.) - Unlimited Custom Measurements (weight, distance, cost, duration, blood pressure) - Notes - Automatic Draft Saving and Resume - Log Search - Filters - Backdating (log past events with the correct date/time) - Stats (insights on your logging activity) - Views (calendar and heat map views that allow for search and filter) - Quick Add (set up quick adds to easily add events to your log with one tap) - Reminders (set reminders + complete reminder to auto-log the event) - Local-First Storage (on device) - Data Export (csv) - Works Offline (no account required) Private. Simple. Yours. Built to Reduce Pressure — Not Add It No streaks. No guilt loops. No “optimize your entire life” pressure. Just clarity when you need it. Log it when you do it. Remember it when you need it. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
