"This isn't just another timer app. This is your favorite timer app's favorite timer app" - Cody Lee, iDownloadBlog. "What I like most about TimeWave, though, is its clean, black-and-white design" - John Voorhees, MacStories. "Liquid Glass really comes to life on its widgets" - Michael Burkhardt, 9to5Mac. "Best iPhone Apps of July, 2021" - Beau Hamilton, Slashdot. WHAT CAN YOU DO WITH TIMEWAVE? TimeWave allows you to combine your breathwork app, your workout app, your focus timer, cooking timer and much more into one single app. You can use TimeWave for: • Breathwork — build custom breathing flows like 4-7-8 Breathing to lower blood pressure, Physiological Sigh to reduce stress and anxiety, Wim Hof Breathing to increase alertness, Box Breathing to relax and much more. • Intermittent Fasting — Create your own intermittent fasting using various splits like 16:8, 12:12, 5:2, etc. You can create timer-splits for each day or for the entire week. • Workout Routines — create your own workouts by chaining excercise and break durations. You can make Tabata/HIIT workouts or even yoga routines. • 20-20-20 Rule — create a timewave to follow the 20-20-20 rule (Every 20 minutes look at something 20 ft away for 20 seconds) while working with screens to prevent eye-strain. • Focus Timers — create pomodoro timers or any kind of work-break timewaves. You are not restricted to 25 minute session, you can create any sequence that suits your preferences. • Cooking — ever had to keep resetting your timers after each whistle? well, now you wont have to. Just create a timewave for each recipe. • Everything — anything else that involves timed sequential tasks. SPECIAL FEATURES: • TimeWave A.I — TimeWave will tell you what has to be done for how long while the Calibre is running. For eg: "Breathe In For 4 Seconds" so you don't have to look at the screen. • iCloud Sync — Available on Mac, iPad, iPhone and Apple Watch and keeps everything up-to to date on all your devices with iCloud Sync. • Black & White UI — B&W is a lot of colours. If you are anything like us, you'll love our ironically modern black and white UI. MORE: • Personal touch — a hand-crafted Indie app. If you have any questions or feedback, you can reach out to us at timewave.team@gmail.com Privacy Policy: https://timewaveapp.com/privacy Terms of Use: https://timewaveapp.com/terms

Presentations that travel with you. Slaide turns a plain-text file into a polished presentation — and this app puts the whole thing in your hand. Open a deck, fix a line, and present it full-screen from your phone or iPad. Everything you need to work on a deck Open any .slaide file or .slaidec bundle and see it exactly as it renders everywhere else — same fonts, same layouts, same theme. Edit the words, swap an image, reorder slides, tighten a headline in the taxi. Present full-screen with speaker notes on your device while the audience sees only the slides. Export to PDF or an editable PowerPoint file and send it from wherever you are. Build a new deck from a sentence (paid account) Describe what you need and Slaide writes it — structure, headlines, supporting points, all laid out in your theme. It checks its own work, renders the result, and fixes what doesn't fit before handing it to you. A pitch on the train. A workshop outline between meetings. A client update you'd otherwise have written at midnight. Your design, applied automatically A Slaide theme is a reusable master: fonts, colors, spacing and layouts defined once. Every slide you write or generate arrives already on-brand, so there's no dragging text boxes on a touchscreen — the one job phones have always been bad at. One source, every format The same file becomes a web deck, a print-ready PDF and a real PowerPoint file with editable text boxes and shapes. Nothing is flattened into pictures, and nothing drifts between formats. It's plain text, so it's yours A deck is a small text file you can read, diff, back up and keep. Slaide's core format is open source under Apache-2.0. If you ever stop using us, your decks still open. Practice your presentation with a coach Want to run through your presentation before you hold it? Slaide has a built in coach that times you and gives you feedback on how well you are hitting the points from the slide. Let it help you find your perfect pitch. Works with decks made in the Slaide desktop app or CLI, so what you build at your desk is on your phone when you need it.
