Super responsive
Have had an account with these guys for a few years now so its about time I did a review. The features are good and I can do all the things I need to edit documents. If something goes wrong they are super responsive and provide fixes/solutions very quickly. Highly recommended.

Mam rada jednoduché a přehledné aplikace nad kterými nemusím zbytečně přemýšlet, neboť to většinou vede k tomu, ze úplně ztratím hlavu a prvotní myšlenku, ktera mě tam zavedla. . Takže v jednoduchosti je krása.

They answered my query really quickly and politely and refunded my subscription within 24 hours as I found I didn’t need it anymore. Fantastic service not often found!

Easy to use
Easy to use. Has an issue with locating my document on my device when done. Took a few minutes to find it in downloads instead of documents.

Easy to Use
It's been fantastic to use to add whole sections into a document without having to re-do everything.
We haven't required something like this often, so I love that I can access this software for free, on an as-needed basis.
Haven't needed to use the software enough to have any issues arise that I couldn't troubleshoot on my own.
