An app where your streak isn't a checkmark. It's the photo you took that day and the time you studied. When you finish studying, take one photo of your book. Pick the time, and the day's record is done. No timer to start and stop. No sign-up. Your calendar fills with your own photos, and the days you've kept going add up. ■ One photo is one day's record · Shoot in the app or pick from your album · Set the time with quick buttons, then adjust in 5-minute or 1-minute steps · A one-line "How far did you get?" note is there only when you want it · If a photo from your album has a capture date, the record is set to that date · You can add records to past days, too ■ The streak comes first · Your streak is the biggest thing on screen when you open the app · Save a record and watch yesterday's 7 days become today's 8, right there · Skim the last 7 days in a single row · Falling short of your daily goal doesn't break the streak ■ A calendar filled with your photos · Each day shows the last photo you took that day · You won't look back at a calendar filled with color, but you will at one filled with your photos · The Album tab lays out a month of photos as tiles ■ One day or one month, as a single image · Turn today's record into a card you can save or send anywhere · For today's card, pick one of five layouts, and leave your profile off it if you'd rather · The month you are looking at in Calendar becomes one image, grid and all · The days you recorded, the time you studied, and that month's recap go on it · Fill a month with no gaps and the seal turns gold. One day missed is silver, two is bronze ■ Set just one daily goal · Monthly and yearly goals are calculated for you · Before you change a goal, see how the results would change · A history of changes shows which goal applied from when ■ See your records from several angles · Monthly: a filled-in grid, total time, and a chart by weekday · Yearly: a chart by month, one photo per month, and the year's total · When a month ends, leave a short recap of it ■ Tag a record, find it later · Add up to five tags to a record, when you save it or when you edit it later · Type in the search field at the top of Album and only the records whose memo or tags match are left ■ Fill in past days · Yesterday's photo or last week's photo becomes that day's record · Album photos are pre-set to their capture date · Import up to 50 photos you already have from Settings. Each one lands on the day it was taken · Studied past midnight? Change the date to the day before, then save ■ Up to three people on one iPhone · Everyone keeps their own records · Tap the profile at the top to switch ■ No account, no server · No sign-up. We never ask for your name or email · Your records and photos stay on this device. The app sends nothing anywhere · If iCloud Backup is on for your iPhone, your records are included and follow you to a new device · No ads. Not even the developer can see what or how much you studied Made for people who study with books every day and want to keep a trace of it: exam candidates, people preparing for certifications, and steady readers.

Verdict

The call

The clearest difference is in-app purchases: StudyStamp at none against 매일공시's 1. StudyStamp also leads on ads (none vs shown). 매일공시's advantage is update cadence (daily vs every 3 days) and device support (3 vs 1). On price there is nothing between them.
