About ArchiFit
ArchiFit (아키핏) is a free workout log app made by OHSEO's (오서네), a one-person software studio in Seoul, South Korea. The developer trains alone, without a coach, and built ArchiFit to answer the question every set raises: what goes on the bar next. The answer comes from your own log.

Why it exists
Training alone means deciding every weight yourself. A paper log or a notes app keeps the numbers but leaves the decision to you, and a fixed program does not know how your last session went. ArchiFit keeps the log and applies a small set of fixed rules to it, so the next set is always one line away. The rules are published in full on How ArchiFit works.
The AI is a second layer that you can switch off. The 8-week analysis on the weekly report runs only if you agree. Logging, the rest timer, records, plans and reports all work without it.
What ArchiFit holds to
- Every number it shows comes from your log. It does not invent numbers.
- No account. Records stay on your phone.
- Summaries and records show what improved. They never mark a set as wrong.
- Its guidance is general fitness information, not medical advice.
