Write it down – Summa does the math. Summa is a notes app for iPhone, iPad and Mac. You jot down your travel budget, below it what’s already booked, and next to the following line you see what’s left per day. Change an amount and the rest falls back into place. No cells, no formula language. Beyond the math, Summa is a fully fledged notes app: headings, paragraphs, a photo in between, lists with boxes to tick off. Notes live in folders, can be searched, pinned, locked with Face ID or Touch ID, and can link to one another. If there’s nothing to calculate, it’s simply a note. The math helps wherever you’d normally run a rough estimate before deciding: a quote where the hourly rate is still open, or the question at which term a lease becomes more expensive than buying, interest included. Play it through first, then decide. The note stays, ready for next time. Values can carry names. Call an amount “rent” and you can use it further down without typing it again. A slider makes a number something you can grab: drag the hourly rate and the quote total moves with it. Longer breakdowns go into tables that calculate column by column; the column total is available to the rest of the note. WHAT SUMMA CALCULATES • Percentages – take off a discount, add sales tax, work out rent as a share of income • Units and currencies – square meters, kilograms, kilometers, kilowatt-hours, hours; dollars, euros, pounds and francs with your own rates, offline too • Dates and deadlines – the days until an appointment, in weeks or months if you prefer; date fields with a calendar • Finance functions – compound interest, savings plan, loan payment, remaining balance, loan interest, savings goal, purchasing power • Break-even points – the year from which two cost curves cross, the point at which a threshold is reached • Case distinctions – a different result depending on a value • Totals – sum, subtotal, average, count • Checkboxes – items count toward the total once you tick them off, not before • Plus input fields, result cards, Markdown and templates to get started CHARTS (PRO) Charts are built from what’s already in the note; you don’t enter anything twice. A table of utility bills becomes a bar chart, a savings plan a curve that shows when you’ll reach your goal. Ten chart types, including several curves from one table. Change a value in the note and the chart moves with it. ON ALL YOUR DEVICES Your notes live in your iCloud and are the same on iPhone, iPad and Mac; what you change on the go is already there at your desk. To pass things on: PDF and HTML, print-ready, with tables and charts (Pro). For other apps there’s Markdown, CSV and JSON, plus a backup of all your notes. ONE PURCHASE, NO SUBSCRIPTION Summa is free for up to three notes of your own, with all calculations, tables, sliders and templates. Summa Pro lifts the limit and unlocks charts and export as PDF and HTML. One purchase for iPhone, iPad and Mac, with Family Sharing. No subscription. PRIVATE Summa needs no account and collects no data about you. There are no ads. The app works offline; your notes live in your iCloud, and the developer has no access to them.

Take back control of your screen time. BlockMyApps helps you spend less time on distracting apps without making your phone frustrating to use. Block apps instantly, create reusable Block Groups, set schedules and daily limits, and choose how difficult it should be to get access again. Whether you want to stop doomscrolling, stay focused while working, spend less time on social media, or simply build better phone habits, BlockMyApps gives you flexible controls that work around your life. QUICK BLOCK Need to focus right now? Choose the apps distracting you and block them instantly. Stop the block whenever you’re ready. BLOCK GROUPS Create groups for different situations — work, study, sleep, family time, social media, or anything else. Choose your apps once and reuse the group whenever you need it. SCHEDULES Automatically block selected apps during specific times of the day or week. Build routines without having to remember to start a block manually. DAILY USAGE LIMITS Set how much time you want to allow yourself in distracting apps each day. Once your limit is reached, BlockMyApps can step in. FLEXIBLE OR STRICT Not every block needs to feel the same. Flexible mode gives you more freedom when plans change. Strict mode adds friction before you can regain access, helping you stay committed when willpower alone isn’t enough. TEMPORARY ACCESS WITH INTENTION Sometimes you genuinely need an app. Instead of making blocking all-or-nothing, BlockMyApps can make temporary access require a deliberate action — giving you a moment to decide whether you really need to open it. DESIGNED TO FEEL SIMPLE BlockMyApps is built around one idea: powerful screen-time controls should still feel easy to understand. See what’s active, what’s coming next, manage your controls, and review your progress — without turning productivity into another complicated system. Built using Apple’s Screen Time technologies. Spend less time scrolling. Spend more time doing what you actually meant to do.
