Unacceptable. ### 3/5 — Need to add auto save feature *2026-02-22, version 3.0.5* Works on a project for hours and when I come back to it it’s all gone. Ridiculous really all it needs is a autosave feature. ### 2/5 — โกรธมากนะ *2026-01-07, version 3.0.5* คือจะเปลี่ยนชื่อแล้วเด้งออก 😡😡 หมายความว่าไง ### 4/5 — Not working properly after update *2025-12-22, version 3.0.5* I can’t tag anything without the menu popping up. Every time I press values the me pops up or it just doeesnt allow me to tag anything. This is only on the iPad, it works fine on the iPhone. However the screen is just too small ### 3/5 — เปลี่ยนชื่ออุปกรณ์ไม่ได้ *2025-12-15, version 3.0.5* ตอนนี้มีปัญหาเปลี่ยนชื่ออุปกรณ์ไม่ได้ กดเปลี่ยนแล้วเด้งออก ### 2/5 — Ficou ruim *2025-11-24, version 3.0.5* Prefiro a versão anterior do app ### 2/5 — แอปเด้ง *2025-11-14, version 3.0.5* แอปเด้งตลอดจนใช้งานไม่ได้ เขียนอะไรไม่ได้เลย ตั้งแต่อัพเวอร์ชั่นใหม่รวนจนใช้งานไม่ได้เลย แก้ไขด่วนๆเลยครับ ### 4/5 — Dúvida! *2025-11-10, version 3.0.5* Essa versão gratuita não simula o funcionamento do comando? ### 1/5 — Simulator not working *2025-10-17, version 3.0.5* My app doesn’t simulate anything, even after paying for the whole package ### 1/5 — redundant *2025-09-29, version 3.0.5* The apps have similar features between simurelay and simurelay full access, causing confusion in repeat orders, and both apps when updated to the full version cannot export files to pdf. แอปมีที่ที่ลักษณะเหมือนกัน ระหว่าง simurelay และ simurelay full access ทำให้เกิดความเข้าใจผิดในสั่งซื้อซ้ำ และแอปทั้งคู่เมื่ออัพเดทเป็น full version แล้วไม่สามารถส่งออกไฟล์เป็น pdf ## Frequently asked questions about Simurelay ### What is Simurelay used for?
