Thanks. ### 3/5 — Can’t try till review *2025-11-11* Would love to give honest review but can’t get past this page to see app ### 1/5 — Doesn’t work without subscription *2025-10-19* Says it’s free but you still have to pay on the app ### 3/5 — Just downloaded *2025-10-08, version 1.1* Just downloaded ### 1/5 — Don’t download *2025-09-27, version 1.1* Free to download but to even use it you have to pay $4.99 it should list the price at $4.99 not free. Total scam ### 1/5 — Bate and switch *2025-09-11* You can’t engage the app without rating (how could that be worthwhile to anyone considering?). Then, you can’t even get so far as to demo the app w/o having to any option but to buy a subscription. Lame. ### 1/5 — Bad *2025-08-08* The app asks you to leave a review BEFORE you open the apps functions. I skipped it and chose “not now”, to find that you can’t run a calculation until you pay $4.99!!!! No wonder they want you to review the app as “free” but it’s actually behind a paywall. Gross look for them. Uninstalling ### 1/5 — Can’t use *2025-07-10, version 1.1* Why would I review your product before I’ve even used it? I can’t use the app without submitting a review. Not a good look! ### 1/5 — Needs to say it charges *2025-06-21, version 1.1* Can’t do anything at all without paying. ### 1/5 — Lame *2025-06-03, version 1.1* Not even a chance to try one calculation without being forced to pay. AKA bait and switch ### 3/5 — Onboarding a pain *2025-02-07, version 1.1* I got this app after seeing it mentioned in App Advice. I was really annoyed by the onboarding process and then having to review the app before I could use it. Not the smartest way to have your customers start off…annoyed. The app is very simply laid out, but a few things are confusing. Some of the contrasts in colors need to be more pronounced so people with vision problems can see. The calculated unit dosing on the syringe should have more contrast from the syringe tick marks. The label under the syringe on the right, “vial contains X doses” is VERY confusing. It implies the calculated results, given the water and peptide strength input, will give you a glass vial sitting on the counter with X (in my case 100) doses. That is totally not correct given my input of .5 mL Bac Water and .5 mL of 10 mg Tirz. So, I think the dev is trying to emphasize the syringe has 100 potential doses based on the number of tick marks on it? But, that is not necessary and is just plain confusing. Plus, the wording in that location is just more visual clutter since it is not useful information pertaining to the calculation just completed. Also, the last input you make, the peptide dose you want, should have the option for mcg OR mg. For example, for Tirzepatide, I will use mg. It is unlikely I will ever go lower than mg strength, even microdosing it. But for Sema or Reta, I will definitely use mcg. So, being able to choose would be nice, instead of having to do the math myself before plugging in the numbers. As far as what I like? I LOVE that you can save your calculations in a history for quick and easy reference. It is nice to have this information available to pull up quickly. It would be great to have an information library on various peptides and what they all do. I am not sure if the dev has that kind of time though. Nice job in general! ## Most critical reviews (10 lowest-rated) ### 1/5 — Scam App *2026-08-29* I purchased a subscription and the app doesn’t recognize it and has kept me in free mode. Restore button doesn’t work and there’s no customer service options. Save your money and stay away! ### 1/5 — Peptide calculator *2026-08-28* I paid for the Peptide Calculator subscription, but the app constantly asks me to subscribe as if I had never paid. It doesn’t recognize my purchase, and I can’t perform any calculations. The app is completely useless to me. It’s extremely frustrating to pay for a service that doesn’t work. Terrible experience and a complete waste of money. ### 1/5 — Useless *2026-03-23, version 1.1.6* You can’t use this app basically at all unless you pay for it. Very misleading ### 1/5 — Won’t Open *2026-02-12, version 1.1.6* Can’t even get passed the splash page. Zero stars. ### 1/5 — $10 to try *2026-02-07* Can’t do anything until you pay the $10 yearly fee. There’s not even a free trial. So I even can’t see what the app looks like in use before they demand non-refundable money? Hard pass. ### 1/5 — Wow why even have a free *2026-02-05* Instant review request, plus you can use the calculator all the way up until you need the calculation then. Buy premium! It’s a calculator why would need a premium ### 1/5 — Horrible *2026-02-03, version 1.1.6* No reason anyone should pay for an app like this. ### 1/5 — Calculation between mcg and mg show different results *2026-01-21* I just downloaded and paid for one month for this app. I plugged in some numbers, 10 mL water, 50 mg in vial and 5 mg desired dose, and got a completely incorrect and nutty answer. I went back and changed the 5 mg desired dose to 5000 mcg and got the correct answer. So, trusting this app to provide the correct answers may not be wise. ### 1/5 — ok *2025-11-05* I really wanted to like this app because I wanted to do some quick calculations but I’m was so put off by the immediate request to review the app and subscribe to premium- at least tell me what it does first! I found the calculator not very intuitive and I was hoping for more information when using the calculator as well, like suggested amounts, etc. If you need some very very basic calculating and you know your stuff then this might work for you- but I just need something a little more robust. ### 1/5 — Not Free *2025-10-19, version 1.1* They make you review before you see the price to get the calculator ## Most praised reviews (10 highest-rated) ### 5/5 — Perfect app for Peptide Enthusiasts *2025-12-15* The new update adds scheduling features and an index of peptides with valuable information on each. You can create your own schedules with existing peptides or any combination or reconstitution you choose. I opened a support ticket on an issue I thought I found and they got back to me in minutes and explained how to resolve my issue, which was my lack of understanding how to use the app. Worth the money! ### 5/5 — Easy to use *2025-11-10* Very easy to use and a life saviour ### 5/5 — Calc *2025-10-21, version 1.1* Great use ### 5/5 — Review *2025-10-19, version 1.1* Great app! ### 5/5 — S *2025-10-03, version 1.1* D ### 5/5 — Awesome *2025-09-23, version 1.1* Great for beginners ### 5/5 — great! *2025-08-20, version 1.1* no none sense! ### 5/5 — F *2025-07-24, version 1.1* Z ### 5/5 — Great App *2025-06-02, version 1.1* Great App ### 5/5 — Accurate peptide calculator *2025-02-06* Review I’ve been using the Peptide Calculator app for a while now, and it has truly exceeded my expectations! The app is user-friendly, accurate, and incredibly helpful for anyone working with peptide solutions. Whether you're a beginner or an expert, this app simplifies the process with precise dosing, reconstitution, and dilution calculations. The clean and responsive design enhances the overall experience, and the app runs smoothly without any glitches. Highly recommended for anyone looking for a reliable and efficient peptide calculation tool. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
