This is a timer application that can be repeated settings and interval settings. You can use this timer when you want to concentrate successively like muscle trying and studying etc. Also, the image might motivate you to do anything. ** The following features are distinctive. ・ Timer mute function ・ Repeat function of timer ・ Setting function of interval time ・ Measure timer stop time. ・ Skip function of timer. (It can be used when you want to move to the next timer because the content in one set is finished early.) ** Supplement ・ I use part of the image made in "Irasutoya"(https://www.irasutoya.com/) for this app.

Verdict
The clearest difference is review sentiment: Depreciation Calculator at 100% against IR's 0%. Depreciation Calculator also leads on rating (4.9 vs 3.0) and ratings volume (11 vs 2). IR's advantage is ads (none vs shown) and update cadence (monthly vs every 28 months). On price, in-app purchases, monetization model and device support there is nothing between them.
