The 100-Envelope Savings Challenge, Without the Printed Sheet
Pick a random envelope, put that amount aside, tick it off. PennyDraw (Savings Challenge) keeps score of the whole challenge on your phone, so there is no sheet to lose.

The problem
The 100-envelope challenge is simple, but the paper version is not: you lose the sheet, forget which numbers you already used, or cannot remember how much you have collected. Most apps ask for an account or a bank link just to cross off numbers. PennyDraw only keeps score: it never holds your money and never asks for a bank, so there is nothing to connect.
How PennyDraw (Savings Challenge) works
- Choose a challenge: 100 envelopes, 52 weeks, 365 days or your own number of envelopes, then a currency and an amount per envelope.
- Tap to draw an envelope. Each draw is random and a number never comes up twice.
- Put that amount aside, in cash or in a savings account of your choice, and mark it done.
- Check what you have collected, what is left and roughly when you will finish, then share a card of your progress if you like.
What you get
- Random, never the same twiceEvery tap fills a random envelope that has not been used yet. The challenge can be 100 envelopes, 52 weeks, 365 days or a number of your own, with the currency and amount per envelope you choose.
- Collected, left and finish dateA summary shows how much you have collected, how much is left and about when you will finish at your pace. It is arithmetic on the numbers you entered, nothing more.
- A progress card to shareMake a grid card of your progress as an image. You can hide the amounts, and the card then shows no figures at all. Free cards carry a small PennyDraw mark.
- Backups and no accountThere is no sign-up. You can save a backup file from the studio menu and restore it on another device. Free runs one challenge at a time; starting a new one asks before it replaces the current one.
- Pro, for $1 oncePro lets several challenges run at once, adds a calendar file with a reminder for your end date and a regular nudge, removes the mark from cards and unlocks seasonal themes (Lunar New Year, Christmas, Lebaran).
Private by design
Your challenges, amounts and settings are kept only in this browser on this device. There is no account and nothing is sent to us or anyone else. Because there is no server, clearing site data or losing the device without a backup file loses everything, so save a backup now and then. PennyDraw does not hold money, connect to a bank or give financial advice; it only counts what you tell it.
Free vs Pro
FAQ
Is PennyDraw free?
Yes. Every challenge type, random draws, the summary, progress cards and backups are free, forever. Pro is $1 once, not a subscription, with a 7-day refund.
Does it hold my money or link to my bank?
No. PennyDraw is a scoreboard. You put the money aside yourself, in cash or in an account you choose. It is not financial advice and does not promise any result.
Where is my data kept?
Only on your device, in this browser. Nothing is uploaded. Save a backup file so a cleared browser or a lost phone does not erase your progress.
What does Pro add?
Several challenges at once, a calendar file with an end-date reminder and a regular nudge, cards with no 1usd.life mark and seasonal themes. One payment of $1, no renewals.
Can I choose my own number of envelopes or amounts?
Yes. Besides 100 envelopes, 52 weeks and 365 days you can set your own number, from 2 to 2000, and any amount per envelope in the currency you pick.
Will it remind me to save?
Free does not send reminders. Pro creates a calendar file that you add to your own calendar app, which then does the reminding. PennyDraw does not run in the background.
