### 5/5 — 15lb

*2020-05-16, version 2.8.5*

Update: after a review they updated and added 15lbs. Awesome! Doesn’t have 15lb weights in settings

**Developer response:** Hi veazeynick,
Apple just approved the update ~15 min ago. I don't know how long the refresh in the app store takes. You should find (4) 15lb plates in inventory automatically. If you don't, then I would recommend uninstalling and reinstalling. Since I made a change to the database to include the 15lb it may not have updated correctly. 

Tip: You can tap on the plate icon after any calculation and update your inventory. No need to go to settings. Tapping change plates automatically takes you to change plates, major plates to major plates etc.

### 4/5 — Greatly Improved App

*2019-06-10, version 2.8.2*

After the developer reached out via email the app has been greatly improved and I am currently reaching out about one last issue that only impacts you if your amount of plates is limited.

My previous review of addressed issues and features requests. I leave it to show the developer does care about the users and is responsive.
I couldn’t find an about button or contact information in the app or on the app page. No link to the developer website so that leaves support and feedback through the review process. There is no way to add custom weights this even common plates like 55lbs aren’t available for your calculations. 55lb plate entries is a must. 

Less important but a definite nice addition to these types of apps.
Custom plate entries would be great for those with 100lb plates or those that use fractional weights.  It would also be useful if there was an entry for the currently used collar pair weight.

Cosmetic:
It would also be nice if the weights were color coded
55lb=red 45=blue 35=yellow 25=Green 10=white
Change plates 
5=Blue 2.5=green 1.25=white
And fractional plates would be nice:
1=red .75=blue .5=yellow .25=green

**Developer response:** Hi Minlas,
Thanks for your feedback. Your suggestions were implemented in Gym Cruncher 2.0.0. In addition, I added three plate loading options, single, per side and quad load options. The quad load option is intended for yokes. I also made all tare switches customizable, both label and weight inputs. Plate coloring is off by default but can be turned on in settings. 

As a reminder, to customize either plate inventories or tare switches just tap on the icon or label. Also, there is no save button as the changes are saved automatically as you type. Again, thanks for your feedback and be sure to update your app to receive the changes.
