LifeCoster
Savings that grow every second
Free · In-App Purchases · Designed for iPhone. Not verified for macOS.
Turn "not buying it" and "time at work" into a number that climbs every second. A calm, motivating way to see your own effort add up — no prizes, just your progress.
LifeCoster turns your everyday effort into a number you can watch grow — second by second.
Decide to skip something you’d normally buy, or start a work session, and the value of that choice ticks upward in real time. Seeing the number climb makes saving and sticking with good habits feel rewarding instead of restrictive.
Three simple tabs, switched at the bottom of the screen:
• MISSION — Register something you’ve decided not to buy (a daily coffee, snacks, a subscription you canceled) with an amount and a period. While you keep it up, the money you’re NOT spending grows every second. Reach the goal and you keep the whole amount; give up partway and it resets to zero.
• WORK — Set your pay and an end time, then start working. Until that time, your earnings grow second by second. Hourly, daily, or monthly pay are all converted to a live per-second rate. Run several at once — main job, side gigs, and more.
• RECORDS — Review your totals for completed and given-up items, and track an overall savings or earnings goal.
ALSO INCLUDED
• Apple Watch app and complications keep the number on your wrist.
• Local notifications cheer you on at the halfway point and when you reach a goal.
• Currency follows your device region automatically (¥, $, €, £, and more), or pick a fixed style.
A NOTE ON THE NUMBERS
The amount you see is a visualization of value created by your own effort — what you saved by holding back, or earned by working. It is NOT real money, points, or a prize, and nothing is paid out by us or the app. It’s not a lottery or sweepstakes. If you’d like to actually save, move that amount into your real savings to turn the on-screen number into money in hand.
We deliberately avoid prize-style hype. The goal is simple: let the value of your own effort stack up in a way that feels good to watch.
ONE-TIME PURCHASE (OPTIONAL)
A single optional purchase removes all in-app ads and unlocks the “Game Style” design (a chase-HUD look). It’s a one-time payment — no subscription — and can be restored after switching devices or reinstalling.
