About CC

When Pure Trace went to the App Store, screenshots became the problem: raw captures had the wrong dimensions, and adding text in Photoshop was painfully slow.

So Pure Canvas was born — import every screenshot at once, apply an edit from one image to all of them, and manage multi-language screenshots in one place. Take Simplified Chinese and English: duplicate the Chinese screenshot and its caption to English, swap in the English captures with one click, translate the on-image text with another, then export everything. Work that took tens of minutes or hours now takes minutes — or seconds when the screenshots carry no text at all.

After Pure Canvas came LessonTally, for tracking the class hours and fees of my family's tutoring and hobby lessons. It was already my third app — and I was drowning in app data. Three apps, and each one needed terms of service, a privacy policy, in-app purchase info, bundle IDs.

So Pure Archive appeared: one rule engine to automate all of it. Set up the rules, type an app's English name, tick a few boxes — and the data for a new app generates itself. No digging through old records at submission time, no reassembling information by hand. Adding an in-app purchase? One tap on the copy button sends the localized IAP details and bundle IDs straight to the AI. Later came symbols management and custom symbols — a nice icon gets saved, copied for the AI to use as-is, so nothing drifts out of style. Frequently used prompts and technical specs found an archive too. With Pure Archive managing the details, LessonTally's design and build went off without a hitch.

Its premise was simple from day one: note what my lessons cost, how many sessions, which day — and deduct the right class automatically, so I always know how many lessons and how much money remain.

Then it started solving real problems one by one. Multiple rules, for weekday and weekend schedules. Pause ranges, so holidays do not eat credits. Check-in gifting, for "attend X, get Y free" promotions. Start and end dates on rules, so logged lessons do not count from zero. Multiple rules per lesson, for summer-versus-term schedules. Course conflicts, so after-school classes cannot collide silently. Ad-hoc lessons, for the class added today. Flexible scheduling, for tutors planning students week by week. Lesson duplication, for students sharing a time slot. Lesson linking, so attending together no longer flags a conflict.

The timetable was rebuilt too: calendar and timeline views — compact, stacked, and list styles for the calendar; full week, workdays, weekends, or the last three days for the timeline. Statistics followed, so students, parents, and coaches can verify hours. The smaller refinements are too many to list.

While helping a friend move and set up their network, I realized there was no iPhone app that could properly assess Wi-Fi quality — none that could even draw a heatmap. NetGraph was born right there.

Macs and iPhones have different Wi-Fi abilities, so the two platforms got deliberately different tools: on top of multi-metric heatmaps, roaming tests and report exports followed — making home Wi-Fi surveys and project acceptance far simpler.

Long nights of coding wore my immune system down, and I caught a viral fever. During those days I wanted to look back at past illness records for reference — I searched WeChat and Notes and found nothing.

So Deermory began: every episode of feeling unwell gets a fresh journal, where vitals, text, and photos are recorded as timestamped entries. Log the medicines at home, set medication plans, deduct doses from the cabinet automatically, and get reminders before something expires or runs low. If days pass without improvement, export a PDF for the doctor so they can judge faster. And since health is worth recording outside of illness too, every metric can be shown or hidden as you like; each member keeps their own emergency card, reference ranges adapt to age and gender, and can be tuned per member. The timeline page strings every journal together — filter by member or journal, lay the records side by side, and the connections between them become obvious.

The domain, icancan.cc, reads as "I can, can" — a reminder hanging on the door: a tool can be small, but you need the confidence to finish it well.
