Money saved
Your actual weekly spend, multiplied by your actual time quit, ticking live.
You tell Nixd what you spend in a typical week. The app calculates a per-second savings rate and ticks the total up every second alongside your streak. There's a section that translates the dollar amount into things — flights, a MacBook, gumballs — because abstract dollar figures stop registering after a while.
How it works
Onboarding asks for your weekly spend. (Not daily — weekly is easier to estimate honestly, and people are more accurate when they think in weeks.) The app divides into a per-second rate and uses your quit timestamp to compute the total saved.
The math:
- $50 / week = ~$0.0083 / second
- 1 day quit = ~$7.14 saved
- 1 month quit = ~$215 saved
- 1 year quit = ~$2,600 saved
For a heavy vape user spending $80/week ($4,160/year), the one-year saved figure is north of $4,000. For a Zyn user buying 3 cans a week at ~$5/can, it's $780/year. The math is unforgiving in both directions.
Why a live counter (instead of just total)
Same logic as the streak — discrete totals stop moving. A live counter keeps the number active. You open the app, the dollar figure has gone up since last time. You can watch $1.50 accumulate during a 3-minute craving wave. That tiny observation reframes the craving as money you'd be lighting on fire.
The conversion math
On the homepage there's a section that converts the saved total into things. The current ones:
- $1,825 = a MacBook (one Elf Bar a day for a year)
- $1,825 = 3 flights to Tokyo (off-peak economy)
- $1,825 = 9,125 gumballs (because why not)
- $1,825 = $1,825 (which is better than 0)
The conversions exist because dollar amounts normalize. A year saving $4,000 starts as exciting and ends as a number on a screen. "Three flights to Tokyo" stays vivid. The conversions live on the home tab and are configurable; we add new ones occasionally.
Updating your spend mid-quit
You can edit your weekly spend any time in Settings. Most people do this once or twice in the first month — initial estimates tend to undercount, and the more accurate number shows up after a few weeks of mental tallying. The total recalculates from the current rate forward; past savings don't retroactively adjust (because they were earned at the old rate).
Net vs. gross
The number on the home screen is gross savings — what you didn't spend on nicotine. It doesn't subtract the Nixd subscription cost. If you want net savings, that's a separate readout in Settings. We default to gross because most users compare against "what I would've spent on vapes," not against "savings minus app subscription."
FAQ
How is the money saved figure calculated? +
It uses your reported weekly spend (asked during onboarding), divides into a per-second rate, and multiplies by the time elapsed since your quit. It updates every second alongside the streak counter. The math: weekly_spend / 604,800 seconds × seconds_quit. The total is your real spend, not a generic average.
What if I lied about my spend during onboarding? +
You can update it any time in Settings. Most people refine the number after a week or two when they have a clearer sense of what a real week's spend looked like — early estimates tend to undercount. Some people purposely set it lower to keep the number conservative. It's your data; we don't validate against your bank.
Why do you convert savings into 'flights to Tokyo' and 'a MacBook'? +
Dollar figures normalize fast. $300 saved feels like a lot for a week; by month 6, $7,800 is a number that doesn't trigger anything emotionally. Concrete equivalents fight that normalization — '$1,825 = 3 flights to Tokyo' is harder to forget than '$1,825 sitting in your savings.' It's a small psychological lever, deliberately.
Does it factor in the Nixd subscription cost? +
No. The savings number is gross savings on what you would've spent on nicotine. The the Nixd subscription is a separate line in Settings if you want to see net savings. Factoring it in by default would understate the amount most users would compare against ("$X I would've spent on Zyn this year"). The optionality is in your Settings.
What if I share a vape with a partner — is the money math still mine? +
Yes. The number you put in onboarding is your share of the spend. Most users dial it down for shared products. The accuracy isn't critical; the role of the number is psychological reinforcement, not precise accounting.
