About

Timelith

Read full description

The app for your most important moments. Some events are more than just entries in a calendar. Your next holiday. The birth of a child. Your own wedding. Your first marathon. Completing a further education course. The start of a new chapter in life. These are the moments we work towards, look forward to and remember for a lifetime. That’s exactly what Timelith is for. Timelith is more than just a traditional countdown app. The app makes time visible: as a countdown, a retrospective, a timeline, a project journey or a personal chapter in your life. Experiencing time Look forward to upcoming events or reflect on how long ago special moments took place. As well as traditional countdowns and count-ups, you can also view the time remaining in different ways – for example, in heartbeats, breaths, steps, hours of sleep or meals. Because sometimes a different perspective can change the way we perceive time. Putting time into context Our lives aren’t made up of individual appointments. With the personal timeline, Timelith weaves past memories, current events and future milestones into a single story. This reveals which moments have shaped you – and which still lie ahead. Seeing time as a journey Some things aren’t a countdown, but a journey. With ‘chapters of life’, you can group related events into a personal timeline: for example, your karate journey, a degree, building a house or a new phase in your life. You choose a tag such as ‘karate’, and Timelith constructs a journey through your life from all the relevant events. You decide for yourself whether an event was a milestone or a highlight – the journey will reflect this accordingly. Shaping time Big goals are achieved step by step. Plan projects with your own milestones and see at any time whether your progress is still on track with the remaining schedule. Whether it’s building a house, further education, a marathon, setting up a business or your next big idea – Timelith supports you all the way to your goal. Preserving time Not every memory is meant for today. With time capsules, you can attach messages and photos to events or milestones and seal them until a date of your choosing. Some messages are at their best when they resurface at exactly the right time. What Timelith offers * Countdowns and count-ups * Personal timeline * Life chapters as a journey through related events * Projects with milestones * Progress analysis tracking time and project progress * Time capsules for messages and photos * Reminders and widgets * Markers, colours, emojis and notes * JSON export and import * Android & iOS Privacy by Design Time is personal. That’s why your data stays personal too. * No adverts * No tracking * No data collection * No user account * No cloud requirement All information stays locally on your device. Timelith Premium The free version is perfect for getting started. With Timelith Premium, a one-off purchase unlocks higher limits – including unlimited active events, projects, widgets, milestones, time capsules and further life chapters. Timelith tracks your time. Not your data.
