Good, but needs a couple of features

I previously gave this repertory app 3 stars after an iOS update that left it glitchy. That rating was perhaps a little generous and at least partly based on the complete dearth of good repertory apps at the time.

That said, those problems have been fixed, and a basic search function has been added. (Thanks!) But I think this 4-star rating is also slightly on the generous side.

I use this app nearly as much as I use RadarOpus. I export my work by email and save it in RadarOpus. I don’t mind the basic interface or email-only export option, and I don’t require fancy analysis options.

However, I would LOVE it if Synthesis would add one simple feature: *the ability to combine rubrics*. Synthesis has been doing great work to clean up the repertory, but there are still myriad incomplete rubrics scattered about, and the ability to merge those would really improve this product.

Feature request #2: The ability to *mark rubrics* in a wider variety of ways. You can already bookmark a rubric, but how about a star mark for favorite rubrics and a blackball, grey-out mark for lousy ones?

Synthesis is hands-down the best modern repertory in homeopathy. This app gets its first 2 stars simply because of the quality of the repertory itself. A little more work could get this app another star.

The only game in town

Been dreaming for years like me about iPhone access to the repertory? Newsflash, the wait is over! There have long been several consumer-level, inexpensive or free homeopathy apps out there of course, but Synthesis Repertory is a contender for the world's top repertory; having it at your fingertips on your iPhone app is historic. As a high-end, professional tool in a niche market, it's priced appropriately. It is easy to use.

If you want truly pocket-sized, on-the-go reportization and don't want to be weighed down by a tablet, run, don't walk to get Synthesis English for your iPhone/smartphone. It's the only game in town.
