You can not beat this app for a one time purchase of $4.99. It’s constantly updated and they are fixing it and adding new features. How I don’t know because it already has almost anything you can think of when it comes to medication dosing, HRT, Peptide reconstitutions with multiple peps and the amount you want. It’s fully adjustable. You can set up schedules for everything with reminders and cycles on and off peptides or HRT. It links to the health app and other health apps to track your progress overtime. Can track your bloodwork results and it will all be graphed out. Same with your weight, mood, hunger, energy, libido, blood pressure, basically everything. This app has made my life so much easier and it’s clearly from someone who uses it themselves for it to be this good at a very reasonable price. Thank you for all your hard work and I’m excited to see what’s to come!!!!
Developer Response
Thank you for taking the time to write this glowing review. It really means a lot and helps since there is so many other options now days. You nailed it though! I use the app myself and rather dislike subscriptions so my goal is just to provide as much value as I can to as many people as possible. I think the abundance mindset will reap rewards. Please let me know if there’s feature or improvements you’d like. Knowing how people use the app is helpful for me. Or improvements in flow and reducing clicks. Next up is a full featured symptom tracking system. And beyond that I’m open to suggestions. Maybe a dashboard and onboarding help tutorial since that is long overdue. And more medication presets. I’m also working to refine the insights tab to surface better correlations when things like weight or lean mass are trending with a specific medication. Thanks again!
Love this app! Makes life much easier.

Glad I chose this app when starting my GLP-1 journey. I used a different app before this one and this one is far superior in my opinion, especially when you consider the amazing pricing. I wanted privacy and didn’t want yet another subscription service I’m endlessly paying for. So far I have seen this app grow leaps and bounds from where it started and each update continues to make the experience better and better. It’s easy to store and track all of my different protocols and I love the insights and tracking that help me achieve my goals.
Excellent Tool

This is a fabulous tool for dosing calculations, protocols, and schedules. The reminder feature is great and very adaptable. Dosing can be edited ‘on the fly’ and the feature showing doses per vial/amount left per vial are great features. It has been very beneficial and the app is very ‘feature rich’ in my opinion. A huge plus - it is updated and improved often!
Incredible value and updated frequently

Easier to use than all the others and no subscriptions! Developer is very responsive to feature request and continually updates the app. I’m loving the new insights and half-life and biometric features. Thanks for making this!
What's new:
- Fixed a crash that could happen when opening or editing schedules with an end date before the start date.
- Added day-based cycling options for short on/off protocols, with more accurate stock and depletion forecasts for cycling and titrated schedules.
- Improved schedule creation and editing, including the add-today prompt, Mac date display, and safer same-time dose history handling.
- Made iCloud and Apple Health sync catch-up more reliable, with clearer results when data is applied or skipped.
- Polished Insights medication-level charts, metric picker behavior, themed tabs, and several layout edge cases.
