Cant recommend it more!! **Developer response:** Appreciate your support!! It means a lot, we are very grateful for your review and are in the process of pushing even more meaningful updates! Be on the lookout! ### 5/5 — Goodwill bins run secret weapon *2026-03-10* I’ve become pretty good at identifying value stuff just by touch and look but this app has tremendously helped decision making since sometimes you just never know what you’re getting. Now that platforms are removing seller fees tracking my sales on here is instrumental so I can account for shipping, boxes, materials, all costs for my sales. Good stuff!! **Developer response:** We’re glad you found the valuation feature so helpful! Be sure to email us with any suggestions from the app!! ### 5/5 — Easy Margin Tracking *2026-03-10* I’ve been selling on Depop for close to a year now and this allows me to track my margins much easier, I would really like to have it connect to my accounts and automatically track things instead of manual. ### 5/5 — 10/10 *2026-03-10* Loving the new update, 100% recommend! ### 5/5 — Very useful for online reselling *2026-03-09* This app is very good. It really helps me identify products for my online sales. I’m a vintage reseller, and it helps me a lot to identify the garment, learn about its history, and estimate prices. I really liked this app ### 5/5 — Just The Credits are worth it *2026-03-09* the subscription seemed like it was a bit much in my case since I’m just getting started on my reselling journey but I think I’m getting a very generous ai usage out of the credits!! I don’t want to spend much until the business picks up but I can’t deny this honestly provides the value it says it does ### 5/5 — Feels nice and works great! *2026-03-09* I have tried other image based valuation apps and none have been as accurate, it will get stuff wrong but the way I can give it information and go back and forth with it shows it has very good training. Being able to save those valuations in inventory is awesome ### 5/5 — Works Like A Charm!!! *2026-03-09* I had this app before the valuation feature to track my sales on Facebook marketplace and see how I’m doing, but decided to try the trial and had it help me with titles and descriptions and it seems to have really gotten the view count of my items up due to the search engine optimization. Will start to try sourcing with it! **Developer response:** Appreciate your enjoyment! ### 5/5 — Keep these new changes coming!!! *2026-03-09* The app hadn’t gotten an update for a while, but the redesign and new features are why I’m staying. Decided to start a trial on the valuations feature and it is so helpful for listing details it’s crazy just being able to go back and forth with it and seeing my items actually sell faster because of search engine optimization. I’m normally purchasing items online and reselling them as part of raffles or buying on release but I think it’s going to be really useful with sourcing moving forward, kind of want to hide this app from people 😅 **Developer response:** Glad you're enjoying! Do not hesitate to let us know about feature requests from the settings! ### 5/5 — Great App For Resellers *2026-03-07* This app makes it super easy to keep track of all inventory you have and makes tracking your sales even easier. The perfect tool to have if you resell, I would recommend this to everyone. The developers care about this app and have been pushing recent updates which have fully revamped this app making it clean and easy to navigate. They even went as far to listen to an idea/vision I had for the app that I emailed to them and in about a week and a half it was added. **Developer response:** Thanks Weston! Greatly appreciate you and your recommendations! ## Frequently asked questions about TREASR ### What does TREASR: Inventory Calculator do?
