SIM — Gym Edition Changelog

v0.7.0 — Sep 28, 2026

New

Automatic crash reporting: the app now reports crashes and errors as they happen, so issues can get diagnosed and fixed faster — without needing to remote into a gym's computer to look around. No member data is ever included; only technical error details.

v0.6.1 — Sep 28, 2026

Fixed

Day passes and single-session packages no longer disappear into old records: buying another 1-day gym pass or 1-session class while a prior purchase of the same package was still "active" silently merged the new sale into the old subscription instead of recording a new visit — so staff would see nothing new after taking payment. Every single-visit sale now always creates its own record.
Packages can no longer be saved with a Duration of 0 and no Session Count — that combination produced subscriptions that never expired and were treated as permanently active, which is what caused the bug above.

v0.6.0 — Sep 15, 2026

New

Personnel attendance report: staff clock-in/out via card swipe now generates an attendance report, no separate timeclock needed.

Fixed

Timezone correctness: pinned the app to GMT+8 with whole-day date boundaries — fixes a class of bugs where reports and check-ins near midnight landed on the wrong day.

v0.5.1 — Aug 1, 2026

Fixed

Fixed the financial dashboard returning zero results when the date range collapses to a single day (Date From equals Date To).

v0.5.0 — Jul 15, 2026

New

Financial dashboard: revenue actuals and forecasts, daily breakdown, average transaction value, and member counts in one view.

v0.4.3 — Jun 3, 2026

Fixed a GROUP BY bug in payment status recalculation
Added a Windows EndPagePrinter fix for receipt printing

v0.4.0 — May 27, 2026
