Nest is a savings challenge tracker. It includes ready-made challenges — 52-week, 365-day penny, no-spend, 100-envelope, 26 paydays and 30-day — plus a custom challenge builder, savings goals with target dates and an emergency fund tracker. Progress is shown as something that grows, from a seed to a young tree.
Saving is hard to stick with because progress is invisible — money in a savings account just sits there. Nest makes each deposit visible and gives you a plan, a pace and a finish date, so it is easier to keep going.
52-week, 365-day penny, no-spend days, 100 envelopes with a random draw, 26 paydays and 30-day challenges, each with a one-tap tick board.
Any target, any timeline, with a live preview before you start.
Goals with target dates, with the maths done for you per day, per week and per paycheck. Use them as sinking funds for big expenses.
See how many months of expenses you have covered, with a "fund this first" mode.
Streaks grow from seed to sprout to sapling to young tree, and each challenge fills outward like tree rings.
A finish date based on your real progress, and what-ifs like "what if I save $20 more a week?"
Fell behind? Add a little extra or stretch the timeline — no guilt.
Log a save on your phone and see it on your laptop. Encrypted, up to 4 devices.

Nest is built on the idea that people keep doing what they can watch grow. Every challenge has a board, every tick makes something bloom, and streaks grow through stages — seed, sprout, sapling, young tree. Each challenge fills outward like the rings of a tree. The home screen tells the story of your savings from top to bottom.

Every challenge has a one-tap tick board. Not sure which to choose? Our 52-week savings challenge guide compares the main variations, including versions for people paid every two weeks.
For each goal, Nest works out how much you need per day, per week and per paycheck to hit your target date. As you save, the "at this pace" projection updates with a realistic finish date based on what you've actually done. If you fall behind, Nest offers specific ways to catch up — add a little extra or stretch the timeline — instead of a red warning.
What-if scenarios answer questions like "what if I save $20 more a week?" with how much sooner you'd get there.
Savings goals with target dates keep every financial goal in one calm place. Many people use them as sinking funds: saving a little each month for the big expenses — insurance, holidays, car repairs — before they arrive. Our article on safe to spend shows how sinking funds keep a monthly budget steady.
The emergency fund tracker measures your savings in months of expenses covered, which is a far clearer milestone than a round number. "Fund this first" mode puts it ahead of other goals until it's done.
Nest is a tracker: it doesn't move or hold your money. You keep your savings in your own bank account and record each save in Nest.
Saving is unusual among money habits: when it's going well, nothing happens. The money just sits there, and it's easy to feel you've achieved nothing. Nest makes the invisible visible.
None of this changes the maths of saving. It changes how likely you are to keep going long enough for the maths to work.
Nest has no account and no bank login. Your data stays on your own devices. Link your phone and laptop once with a 6-digit code or QR, and a save logged on your phone appears on your laptop a moment later — encrypted on the device before it travels. A device that was offline catches up when it reconnects.
Nest installs from your private link on iPhone, iPad, Android, Mac, Windows and Chromebook and works offline once installed. It has four calm themes (Meadow, Pine, Light and Dark), 30 currencies, keyboard shortcuts, printable reports and challenge boards, and JSON backup and restore.
Flow shows what's safe to spend each week, so you know how much can go to savings. Vault combines goals and challenges with a full budget and net-worth tracker.
Nest is a tracker — it doesn't move or hold your money — and it is a motivation tool, not financial advice.
