Tiptop Project Pro
Plan your projects with a PERT network. You describe the tasks and what depends on what; the software calculates the dates, the slack and the critical path. Simple and fast, on Mac, PC, iPhone and tablet.
Online beta only: it runs in your web browser, free, with no sign-up and no account, and already works on Mac, PC, iPhone and tablet. The Mac, iPad and iPhone app will come to the App Store later.

Everything you need to keep a schedule
One project, several ways to look at it. Change a date, a duration or a link in one window: all the others update.
Three themes, to your taste
Theme menu: change the look of the software in one click. Each theme has its own windows, buttons, icons and fonts, light or dark. Your projects stay the same.




The permit, the photos, the quote: on the task
Attach files to any step: the building permit as a PDF on “Permit granted”, site photos, a Word quote, an Excel sheet. A small paperclip marks the tasks that have some.
- Right-click the task (long press on phone and tablet), or simply drag the file onto it on a computer.
- View images and PDFs right in the software.
- Take them along: attachments are included in the project’s saved file.
One tap, and it’s on your home screen
Tiptop Project Pro opens in your browser and installs like an app, without the App Store. It already works on Mac, PC, iPhone and tablet. On phone and tablet the interface adapts: one window at a time, tabs at the bottom, every menu in the “Menus” button at the top left, touch gestures to link tasks.
- Open the beta in your browser: Safari on iPhone and iPad, Chrome or Edge on PC and Android tablets, any browser on a Mac.
- Install it: on iPhone and iPad, tap Share then “Add to Home Screen”; on a PC or Android tablet, choose “Install” in the browser menu.
- Launch it from its icon: it opens full screen and works even offline.



A question? Just ask it
In the Help menu, “Ask a question” opens a small chat window. Write in your own words: the assistant searches the user guide and shows the passage that answers, with a button to read the whole topic.
- Ask: “how do I link two tasks?”, “why are my tasks red?”.
- Read the answer, or open the full topic of the user guide in one click.
- Nothing leaves your device: it works even offline.
No account. Your projects are yours.
Nothing is sent over the Internet. Projects can be kept in two places, and the software always tells you where you stand.
In the browser
Every change is saved automatically, on the device you are using. Handy, but fragile: if you clear the browser’s data or change device, those projects are gone.
In a file
“Save to a file” creates a file you keep wherever you like: a folder on your computer, iCloud Drive, Dropbox, a USB stick. Kept in iCloud Drive, it is on your Mac, iPad and iPhone.
A “full backup” also gathers all your projects into a single file.
User guide
Twenty-two topics to get started: first steps in five minutes, themes, the outline, the network, dependencies, date constraints, resources and costs, attachments, saving, PDF export, shortcuts. Currently in French; the software itself is in English and French.
One-page PDF export
The schedule or the PERT network fits on a single A4 or A3 page, readable and ready to print or send, with the critical path in red.

Ready to plan?
The online beta is open to everyone, free. The App Store app will come later. A sample project (building a house) is included so you can explore in a few minutes.
Beta: more features are on the way (resource levelling, cost charts, cash flow). Remember to save important projects to a file.
