About

Yajak

Features
Read full description

“Yajak” is short for “nighttime work,” a term used in Korean art schools. If you draw or paint, you probably know the feeling of losing track of time with a piece, day or night. Record each session, keep it with the artwork, and see all those hours come together in a finished piece. Choose an artwork and start the timer. Add a process photo and a work note after a session, then revisit the dated entries and see time accumulated for that piece. Add material costs when useful. Make one card for a work in progress and another for a completed piece. Choose which details to show before saving or sharing. Rotate or crop a photo, compare two photos from the same artwork, and save a stored personal card back to this device. In a shared workroom, choose the artwork and attachments to connect. You can open the connected copy again from your personal library. When iCloud is unavailable, records are kept on this device. iCloud sync depends on a usable Apple Account and connection. Keep a separate .yajak backup of important records. Restoring a backup replaces the current records on this device with the selected file. Yajak Early is a one-time, non-consumable in-app purchase through the App Store. It raises the limit for active workrooms you own from one to three total; rooms you join are not counted. A verified purchase can be restored to the current Yajak account. Purchase restore does not restore artwork or work records.

Verdict

The call

The clearest difference is in-app purchases: Yajak at none against Reminder's 6. Yajak also leads on update cadence (weekly vs every 5 weeks) and device support (3 vs 1). Reminder's advantage is ads (none vs shown). On price and iOS requirement there is nothing between them.
