Creators of magic: PLEASE consider teaching as a separate skill that you need help with unless you're already an accomplished teacher. We would say to someone who wants to get into magic: please study and get mentoring before performing. Same thing with teaching.

The trailer has subtitles but the instructional video does not. When trying to focus on overcoming cultural differences on how English is pronounced, it's harder to follow the instruction. Please include subtitles.

Also, please tech magicians, slow it WAY down. There are clicks and steps done that are obvious to the teacher but not to the student. Some of this may be facilitated by a generational divide. (Again, trained teachers know all about this and what to do to overcome it effectively.)

Also, if you make a mistake please stop, rewind, and tape again. Mistakes are another distraction. Moreover, welcomed is an outline of what's to come at the start of the video.

If I can rewind enough times, and overcome the significant teaching limitations, this sounds like it will be a wonderful addition to my repertoire.

(Please excuse me if I sound too critical. This is just an ongoing theme that I don't see many discussing within the magic community.)

As a hobbyist who enjoys dabbling in mentalism and sharing fun moments with friends, I’m always on the lookout for effects that are clever, practical, and pack a punch. NUMERIS hits all the right notes.

From the moment I started playing around with it, I was impressed by how smart and elegant the method is. It doesn’t feel like just another app—it feels like a well-thought-out tool designed by someone who really understands. The simplicity on the surface hides an ingenious core that makes the effect feel like real mind reading.

I’ve already had some amazing reactions performing this casually with friends. It’s the kind of effect that sticks with people, and because it’s always on your phone, it’s perfect as an everyday carry (EDC). You don’t need to set up anything elaborate—just pull out your phone and go.

What’s also fantastic is the community Juman has around NUMERIS. His private Facebook group offers creative ideas, and alternate handlings, that really add value beyond the app itself.

If you’re into mentalism—even just casually like me—and want something you can perform anytime, anywhere, NUMERIS is a must-have. Highly recommended.

I purchased this trick after watching a world class magician perform it at the Magic Castle. The usefulness of the effect is the variety of applications. It forces a number of your choice. This could be a card value, dice roll, serial number, anything numeric. Only limitation is imagination.

Drawbacks. IOS only. Works only on Basic Calculator mode. be careful of screen orientation portraits vs landscape. I installed on an iPad mini and it works just fine. Minor issue with scientific notation on larger numbers, but switching to landscape mode usually fixes it.

Originally, I was reluctant to install foreign software, but the gimmick involves just some shortcuts and you can inspect everything before enabling. So, I am ok with that.

I haven’t tried it yet, there are two additional modes beyond the stored force. One is what they call on the fly, you can change the forcing value using a shortcut. I opted just to alter the existing code to the number of my choice. Probably easier than using their feature. Second is a voice activation, I am working that one.

This trick works with the newer versions of the iOS (18 and up) and probably works with legacy as well. The video gives a Facebook Group and the author’s personal email. Seems like he really stands behind his work.


If you have any desire for calculator magic and a unique way to force a number, I highly highly recommend this product. The magician I saw using it had a very creative implementation that kept us wondering and he kept getting us to give him more and bigger random numbers through his 20 minute show. He used this as his finale, it is that good.

I would like to say a huge thank you to the author, I had some problems with my phone and he helped me solve it very quickly.

The trick works and it is very cool!
I recommend it to everyone!

I love the ease and dependability of Numeris. It is a real convincer and the audience has no clue in the hidden intelligence of ‘Numeris’ .The best part is that every member in the audience is following along on their phones and finally all arrive at the forced number. There is no room for thought or doubt. There are various routines that can help you with yhe reveal.

Numeris turned out to be one of the most deceptively clever pieces that I’ve added to my repertoire.

The method is shockingly simple, yet flies completely under the radar, perfect for both stage and close-up scenarios. There are no gimmicks, no preshow, no apps, just smart thinking and structure. It blows people's mind away when delivered with the right pacing and tone.

Some people might need to put in a bit of effort to learn it properly but it's not hard at all. Once you get the knack of it you are going to love it!! It plays strong, resets instantly, and fits in your pocket (EDC). Also the additional stuff provided in the private Facebook group (the date and time force, the visual routine etc) is very creative and well thought out.

If you enjoy elegant methods that let your performance shine, Numeris is quite a killer.

Highly recommended.
