GeCla vs EduCITY
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
GeCla
This app lets you create and identify patterns based on symmetry. It helps users understand geometric transformations and provides feedback on classification accuracy. It also features a competitive mode for two players.
- Generate patterns with chosen symmetry
- Classify patterns, friezes, and rosettes
- Assisted classification with error reporting
- Competition mode for two players
- Multi-language support (PT, EN, IT, GE, SP)
- Symmetry information encoded in image files

GeCla, short for Generator and Classifier, allows the user to generate a pattern, a frieze or a rosette with a previously chosen kind of symmetry starting from an asymmetric motif. It also allows the classification (with or without help from the program) of the patterns, friezes, rosettes obtained in this manner. In the end, the program provides a report of the errors committed. GeCla already has versions in five (PT, EN, IT, GE, SP) languages. The generator writes encoded information about the existing symmetries in the jpg image file generated. Then the classifier reads and interprets this coded information, which allows it (according to the level of aid chosen) to give information about how the classification process is going, preventing wrong choices, or only indicating at the end whether the classification is correct and, if not, indicating the first mistake. GeCla also includes a competition option. In it, each player generates a pre-agreed number of images and then both exchange images and each classifies the other's images. All steps are managed by the program, which in the end provides a report on eventual mistakes.

A app EduCITY (https://educity.web.ua.pt/) permite explorar a cidade através de jogos educativos de localização que integram recursos multimédia em realidade aumentada (RA), com vista à mudança de atitudes dos cidadãos em prol do desenvolvimento sustentável. A ideia é promover cidades sustentáveis, criando um ambiente inteligente de aprendizagem suportado pela app EduCITY. Esta app dá acesso a jogos educativos com desafios interdisciplinares atrativos, pois integram recursos multimédia em RA, como simulações com base em dados de sensores ambientais, animações 3D, spots informativos, entre outros. Os jogos são desenvolvidos com o objetivo de serem explorados por cidadãos, de todas as idades, em passeios pela cidade, sendo cocriados pela comunidade escolar, académica e geral, através de uma plataforma web aberta (https://educity.web.ua.pt/adminjogos/index.php). Esta pedagogia inovadora usa tecnologia familiar (dispositivos móveis) para “aprender fazendo”, na qual os jogos em RA permitem consciencialização ambiental na cidade – laboratório vivo de experimentação – onde os cidadãos são “cientistas ativos” e agentes de mudanças sustentáveis, numa lógica de ciência cidadã. A app EduCITY foi desenvolvida no âmbito do projeto “EduCITY – Cidades inteligentes e sustentáveis com jogos educativos móveis em Realidade Aumentada criados por e para os Cidadãos”, com financiamento da Fundação para a Ciência e Tecnologia (ref.ª PTDC/CED-EDG/0197/2021), de 2022 a 2024. Neste projeto colaboram quatro unidades de investigação: CIDTFF, CESAM, DigiMedia e IEETA da Universidade de Aveiro.

Verdict
The clearest difference is update cadence: EduCITY at every 8 days against GeCla's every 4 months. GeCla's advantage is iOS requirement (11.0 vs 14.0). On price, ads, in-app purchases and device support there is nothing between them.
