A mobile-friendly digital saving challenge is a PDF file designed specifically for use on your phone or tablet. Unlike a printable, you don't need to print anything — simply download the file, open it in Adobe PDF Reader, and track your savings progress directly on screen. It's the easiest way to run a savings challenge completely digitally.

Both are digital PDF files, but they serve slightly different purposes. The mobile-friendly digital challenges are simple, clean, and designed for quick everyday use on your phone — ideal if you want a straightforward savings tracker with minimal complexity. The digital workbooks are more comprehensive, with hyperlinked pages and a fuller interactive experience, and are best suited for use on a tablet with a stylus in apps like GoodNotes or Notability.

Our mobile-friendly digital challenges are compatible with Adobe PDF Reader, which is free and available on both iPhone and Android. No paid apps are required — just download Adobe PDF Reader, open your challenge file, and start saving.?

We currently offer three mobile-friendly digital saving challenges — the 100 Envelope Savings Challenge, the 52 Weeks Savings Challenge, and the Denomination Savings Challenge. All three are available for instant download at $60 TTD each.

The printable version is a PDF you print on paper and use as a physical tracker. The digital version is designed to be used entirely on your phone or tablet — no printing required. If you prefer tracking on paper, choose the printable. If you prefer keeping everything on your device, choose the digital version. Both are available in our Digital Products section.

Once your purchase is complete you'll receive an email with a download link. Your file is available instantly — download it to your device, open it in Adobe PDF Reader, and get started straight away.
