## What is DayVow?

DayVow is your daily challenge, with proof at the end. Start free with a 7 day beginner week, or pick one challenge, choose its length (30, 60, 75, 90 or 100 days) and hard mode or soft mode. Then show up every day.

START FREE: THE BEGINNER WEEK
One rule, 7 days, no card needed. Pick the one rule you want to build from your challenge's list, or write your own. Miss a day and it is counted, you keep going. Finish the week and level up to a longer challenge with more rules. The free beginner week is one run per install; you can start it over while it is running.

BEGINNER, SOFT OR HARD
Soft mode: missed days are counted and the challenge goes on to the end. Hard mode: miss a day and you restart at day 1, with your history kept. Switch from hard to soft whenever life happens. The fail screen is never a dead end.

FIVE PRESETS, OR YOUR OWN RULES
Every preset suggests a length, from a 30 day no sugar reset to a 90 day fitness glow up.
- Fitness Glow Up: move every day, drink your water, protect your sleep.
- No Added Sugar: read the label, swap the sweet drinks, keep the whole fruit.
- 90 Day Savings: log every purchase, skip the impulse buys, move money to savings.
- Read Every Day: 20 pages a day, about four books in 60 days.
- Digital Detox: no phone around sleep, phone-free meals, a cap on the apps that eat your time.
One to five rules, every day or a few times a week, required or optional, with suggestions one tap away. Or write your own rules, give your challenge a name, and rename it any time.

LOG TODAY, SEE YOUR DATES
Tick your rules and tap Log today: the day locks in, with a few seconds to undo a mis-tap. Today shows your day and the date your challenge ends. Every check-in gives you a day card: DAY 23 / 90, your streak, your mode, your day 1 photo next to today's.

THE PROOF
A photo a day in a timeline with one cell per day; tap a day to see what you ticked. A before and after collage, day 1 against the last day, ready to save or share. Photos never leave your phone: no account, no upload. Photos are optional when you write your own rules.

FINISH STRONG
Log the last day and the celebration starts at once: your score (84 of 90 complete, or Perfect with no misses), your collage, a result to share. Every finish joins Your record.

KEEP GOING
Keep going for another round of the same challenge, level up after the beginner week, or start a new one: finished challenges stay in History with their photos and collages. In soft mode you can change your rules any time, from the next day; in hard mode the rules are set for the round and change when you keep going.

THE LOOP
A daily reminder at the time you pick, with your challenge's name. A streak-save nudge when the day is still open. A Home Screen widget with day N of your challenge and today's status.

DayVow is a wellness challenge tracker, not medical advice. The fitness and no added sugar presets follow public health guidance listed in the app under Sources. If you have a health condition, talk to your doctor before changing how you eat or exercise.
